Charli XCX and GLP goes crazy thanks to Elliot Mountford

At the age of 16, Elliott Mountford launched Ti22 lighting design company with a view to providing lighting and video integration on live shows. Little more than a few months later he was handling his first arena show at Wembley.

Now still only 19, and from a background in programming, Elliott has work fully as a lighting designer. Most recently he has been creating a lighting show with Charli XCX—with an armoury of GLP fixtures for company, supplied by Liteup.

“We had 34 X4 Bars and 34 JDC1 [hybrid strobes] on the European and USA tour, and then the show at Brixton Academy was a total upscale, with a total of 96 JDC1s and 36 X4 Bars,” he reveals. The rig comprised both the touring and Brixton package. “It needed to be bright, and be able to create a thousand different looks out of a single unit …and the JDC1 always smashes that.”

Elliott already has some experience in the field, having worked as an LD with Skepta, Ghetts, Chipmunk and a number of EDM acts (Including Ultra Music Festival, Lost Fre-quencies, Carl Cox and Solomun).
Earlier this year he programmed and tour LD’d rapper Santan Dave for LD Tim Routledge, an award-winning lighting show that helped him gain further recognition.

When Charli XCX was searching for a new LD she realised that Elliott, after operating several of her shows, would be a great match. He stepped up to take the lead role, and proposed a completely different conceptual approach, working alongside creative director, Jed Skrzypczak.

“Charli and Jed loved my work, and kept me on board for the festivals, and the US and European tour,” he continued. The lighting design came together organically, without a brief. “I’ve worked with Jed a few times now, and totally get his vibe. Charli’s future pop music needed to stand out. It was apparent that the Cubes, designed by Jed, were our central focus and so I needed a fixture that could produce a flat soft field of light, but was also easy to complement the rest of the rig.”

@Luke Dyson

The GLP fixtures were the key to ensure all objectives fulfilled. “I’ve used X4 Bars for a while, but JDC1 was a new strobe to me at the start of the year. After using a bunch with [San-tan] Dave, I knew it was a fixture for the future and I was interested to see how far we could push it this time.”

Utilising two JDC1’s per cube, and six X4 Bar 20s on the back (with all other JDC1s audi-ence facing), he quickly got his answer. Elliott ran all fixtures in full mode in order to have as much control as possible. “Every pixel is mapped, and I spent a lot of time putting them into layouts and grouping them in a cor-rect way to allow me to separate the backgrounds, pixels and strobe channels.

@Luke Dyson

“The channel modes are super helpful when cloning from JDC1’s to other in-house fixtures. The strobe plate easily clones to an in-house xenon strobe, and the background module clones perfectly to any LED strobe or fixture, with the correct strobe duration/rate etc.

“I also love the way the JDC allows me to separate the plate priority with the pixels, al-lowing effects to be overlaid on top of each other. There’s a really cool part of the show where we go from every strobe at full, to a very very low UV flicker. We strobed the plate module at a low intensity but fast rate, and kept the pixels on high intensity to give it the push.

“It really messes with your eyes because of the refresh rate effect that was applied. The previous song was very very bright and harsh LED xenon white, and this song was a very dark low light UV. Because of the way a human retina deals with light exposure you could still see the previous ‘white’ song while now witnessing a UV look onstage … super weird. It totally matched the song intro and was the perfect look myself, Jed and Charli were af-ter.”

As for Liteup, this is Elliott Mountford’s regular vendor. “I have always worked with Gordon [Torrington] and their techs are amazing. We had Cy Doitmant as the crew chief and Ben Beverley as system tech. Everyone worked super hard and I will keep using Liteup in the future.”
In summary, the LD says there are many elements that make the GLP fixtures so special. “Wherever I go I see the Bars—everyone has them even in the weirdest part of the world, and they always match. Their dimmer curve and colours are unmatched, and I feel like it’s a fixture I can use on every design.

@Luke Dyson

“The JDC1 is simply by far my favourite fixture of the last two years. I can make so many different looks out of one unit, and you really don’t need many to create something spe-cial. The tilt also makes it a genuinely hybrid strobe; I use it for back light a lot and then back into the audience. I also love the thin strobe look, where the source is just a thin line.

“In fact I don’t think there is another strobe on the market that does LED colour and strob-ing all in one, and that is so widely stocked around the world.”

Both Gordon Torrington and tour manager Wilkie Wilkinson had initially thought it was cra-zy having nearly 100 strobes facing straight towards the audience. “But once Wilkie saw it in rehearsals he realised it was not just a strobe, as we were using it as a pixel device, for a bunch of wipes and hits. And he was super impressed,” Elliott concludes.

Prolight + Sound 2020: event has been cancelled

Prolight + Sound will not be held in 2020. On 12 March, the Hessian Ministry for Social Affairs and Integration issued general decrees prohibiting large-scale events expected to attract more than 1,000 visitors. At the present time, it cannot be assumed that the current situation will have changed by the time the postponed event was to have been held. Therefore, Messe Frankfurt has decided to cancel the event.

It was not possible to hold Prolight + Sound 2020 on the dates originally planned in view of therestrictions introduced against the background of the rapid spread of SARS CoV-2 infections.
“We did everything we could to hold Prolight + Sound 2020 as soon as possible after the original dates and would like to extend our thanks to the response and support from numerous companies and organisations that said they wanted to join forces with us to do so.
We are very sorry to have to cancel the fair. However, we firmly believe that, under the current circumstances, this is unavoidable”, said Detlef Braun, Member of the Executive Board of Messe Frankfurt GmbH.

The next Prolight + Sound will be held from 13 to 16 April 2021

Shanghai Celebrates China’s First Meyer Constellation

Nine Trees Shanghai Future Art Centre, is the new crown jewel for arts and culture in China. The structure houses three theatre spaces equipped with Meyer Sound audio systems. The largest auditorium claims the first Constellation active acoustic system in China.

The Nine Trees Shanghai Future Art Centre in China.

The Centre was conceived from the outset as a focal point for a wide spectrum of arts and entertainment performances, hosting both Chinese and international artists representing the global diversity of music, drama and dance. The task of designing and constructing venues suited to this brief was undertaken by Shanghai’s EPC (Engineering, Procurement and Construction) agency, led by General Counsel Le Shengli and with lead technical assistance from Zhu Shijie, theatre director for the EPC.

The project principals surveyed a number of newer theatres in China and overseas, and soon determined that an active acoustic solution would best accommodate the desired diversity of performances. After evaluating available systems, they narrowed their focus to Constellation and initiated consultations with Meyer Sound’s Chinese distributor, Shanghai Broad Future Electro-Technology, Ltd.
“Constellation offers greater flexibility and convenience for future operations,” says Zhu Shijie, “and accommodates a broader spectrum of show programs. Also, when comparing to the alternatives, we thought that Constellation could bring over a purer and more involving listening experience than what the others could offer.”

1 200 places, variable acoustic thanks to Constellation by Meyersound

The 1,200-seat main theatre, also made for hosting operas.

To confirm their decision, Mr. Le and Mr. Zhu traveled to the Meyer Sound headquarters in Berkeley, California to experience Constellation’s acoustical capabilities firsthand in the Pearson Theater and also to see how Constellation’s software, hardware and human design elements are seamlessly integrated. “This experience redefined my understanding of what an active acoustic system really is,” comments Mr. Zhu, “and explained the critical importance of precise installation to the success of the project.”

Constellation is installed in the main theatre, which accommodates 1,200 patrons on two levels. The balanced physical room acoustic, with a reverberation time of about 1.2 seconds, can be enhanced with times up to about seven seconds.
In addition, the subtle characteristics of the reverberation envelope can be altered by adjusting the warmth, strength and brightness. During commissioning and tuning, 11 presets were created for different performance requirements, with additional presets open for future needs.

The Nine Trees Main theatre as seen from the balcony.

The Main theatre whith a short RT made on purpose to fully allow Constellation to create the desired ambience. The hanged mics are visible.

The desired acoustical characteristics are created via a total of 160 self-powered, full-range loudspeakers (Ashby™-5C, Ashby-8C, UPM-1XP, and UPJunior-XP) mounted laterally and overhead, with the lowest octaves reproduced by 16 compact subwoofers (12 UMS-1XPSM and four MM-10XP).

To capture the acoustic ambience, 56 miniature condenser microphones are distributed throughout the space. In between the microphones and loudspeaker output, a D-Mitri® digital audio platform comprising 21 modules provides the sophisticated DSP and matrixing, with five modules — one for each reverberation zone — dedicated to hosting the patented VRAS acoustical algorithm. The theatre’s 30 meter-deep stage is served by a dedicated Constellation zone functioning as a virtual acoustic shell.

For direct sound reinforcement, the main theatre provides a system anchored by dual arrays of 13-each LEOPARD™ line array loudspeakers, with deep bass from four 1100-LFC low frequency control elements. Also deployed as subsystems for fills, delays and foldback are a total of four UPQ-1P, two UPQ-2P, two UPM-1P and 14 MM-4XP loudspeakers along with six MJF-210 stage monitors.
Mounted over the proscenium — concealed behind a scrim — is a left-center-right system configured with 12 JM-1P and four UPQ-1P loudspeakers for, respectively, far- and near-field coverage. Three Galileo® GALAXY™ 816 processors enable system drive and optimization.
Since opening, the Constellation system has been used for a variety of performance genres, including symphony orchestra, drama and musical theatre. The results, according to Operating Technical Manager Li Yiting, have been uniformly excellent.

“In addition to the available acoustic presets, we can fine-tune the parameters to suit the needs of the performers,” she reports. “We conclude that the operation of the system is stable, responsive, naturally reverberating and comfortable sounding. More importantly, you can’t perceive that the reverberation comes from electroacoustics. The best way to put it is that the applause from the audiences and the response from the performers demonstrate their satisfaction with the system.”

The Nine Trees 500-seat multi-functional theatre seen from the rear of the venue.

Regarding the LEOPARD-based reinforcement system, Ms. Li comments that “though it is relatively compact and lightweight, it has tremendous power. It not only sounds clean, but it also enhances the intelligibility and clarity of the sound.”

The two smaller venues in the complex also are furnished with Meyer Sound reinforcement systems.
The 500-seat multi-functional theatre relies on a system based on 12 LINA line array loudspeakers and six 750-LFC low-frequency control elements that can be flown or ground stacked as needed for the event at hand. Completing the system here are two UPA-1P loudspeakers, six MJF-210 stage monitors and a GALAXY 816 processor.

300 seats and a very nice lights mood for the nine trees smallest theatre.

The smallest yet able to welcome 300 patrons theatre.

The 300-seat theatre is covered by two CAL™ 64 loudspeakers with advanced beam steering for the main system, augmented by two 750-LFC elements, two UPJ-1P loudspeakers, six MJF-208 stage monitors and a GALAXY 816 processor.

Summing up the supporting role of the new technologies, EPC General Counsel Le Shengli says, “The goal is to make the theatres more international, more iconic and more artistic. We aim to make Nine Trees Shanghai Future Art Centre a place that belongs not only to the Fengxian District but to all of Shanghai and, more importantly, a home for artists from throughout the world.”

Overall design of the entire Centre was by the French firm Frederic Rolland International, with theatre design by Thomas Yee of San Francisco-based STUDIOS Architecture. Physical acoustics for the theatres — optimized for Constellation in the main auditorium — were designed by Joseph Myers, president of the renowned Kirkegaard acoustical consulting firm.

Martin Audio unveils five new ADORN-Winning ceiling loudspeakers

Martin Audio’s busy start to the year sees no sign of slowing down having unveils a further five new products targeting commercial installation sector with in-ceiling and pendant loudspeakers joining the ADORN series at ISE 2020.
The ADORN commercial series of on-wall loudspeakers was first introduced in 2019. This has now been expanded by three in-ceiling loudspeakers and the company’s first ever pendant speaker, available in white or black as standard.

Martin Audio ADORN on-wall and ceiling loudspeakers bring class-leading performance, reliability and value to a wide range of commercial sound installations, from retail outlets, bars and restaurants to corporate offices. With Martin Audio’s signature sound characteristics, the ADORN series is the perfect choice for background and foreground systems which require superior sound quality from visually discreet, ultra-compact enclosures.
They also provide a seamless sonic transition within a multi-zone complex using larger Martin Audio systems such as CDD or BlacklineX. This ability helped the new ADORN family members win a Best of Show Award at ISE 2020.

All the new ceiling models have a nominal impedance of 16 ohms, enabling four or more speakers to be driven in parallel by one amplifier channel, thereby maximising efficiency and minimising cost. The new ceiling additions are also fitted with an internal high-quality 70V/100V multi-tap line transformer with a switch to select the output level. For full-bandwidth protection, the low and high frequency sections are individually protected against overload in all models.

Comprising a 4” (100mm) LF driver and a 0.75” (19mm) silk-dome tweeter, the ACS-40TS in-ceiling speaker produces 108 dB peak output at 1 m and its ported design delivers strong bass that extends down to 73 Hz. The very wide 180° conical coverage of the ACS-40TS makes it particularly suitable for low ceilings and reduces the number of speakers required for even coverage, leading to a reduction in installation cost. It features a shallow backcan for installation in ceilings with a minimum cavity depth.

Featuring a 5.25” (100mm) LF driver and a 0.75” (19mm) silk-dome tweeter, the ACS-55TS in-ceiling speaker produces 113 dB peak output at 1 m and its ported design delivers strong bass that extends down to 79 Hz. The wide 150° conical coverage of the ACS-55TS makes it particularly suitable for low ceilings with a shallow backcan for installation in ceilings with a minimum cavity depth.

The in-ceiling ACS-55T with a generous internal volume maximises low frequency output and delivers strong bass that extends down to 62 Hz. It also features a wide 150° conical coverage.
Finally, the ACP-55T pendant speaker features a 5.25” (100mm) LF driver and a 0.75” (19mm) silk-dome tweeter, produces 109 dB peak output at 1 m and delivers superb sound quality for both music and speech reproduction. Its stylish pendant enclosure is equipped with a single-point mounting system plus provision for attaching a safety cable. Available in black or white, it also features a wide 150° conical coverage.

You can hear the award-winning ADORN ceiling and pendant loudspeakers alongside the rest of the Martin Audio catalogue at the first of this year’s UK Open Days, taking place March 17-19 at our headquarters in High Wycombe.

Howard Heckers & DiGiGrid for Kings of Floyd tribute

Kings of Floyd are a leading Pink Floyd tribute band based in Germany. FOH engineer, Howard Heckers is the band’s audio lynchpin in helping to produce the authentic Floyd sound. Central to his setup for Kings of Floyd is a DiGiGrid IOS unit.

Led by Brit, Mark Gillespie, this assembly of international musicians regularly undertake national tours, playing popular theatre venues to sold out audiences. In order to replicate and do justice to the magic and majesty of Pink Floyd, Kings of Floyd and their experienced crew place audio quality high on their list of priorities.

The sound guru Howard Heckers with his double screen LV1 virtual desk.

Highly respected FOH engineer, Howard Heckers, notable for his work with Supertramp co-founder Roger Hodgson amongst many others, is the band’s audio lynchpin and his work in helping to produce the authentic Floyd sound is essential.
Central to his setup for Kings of Floyd is a DiGiGrid IOS unit, as he explains: “I’ve been a DiGiGrid user for a while now, having started touring with the Waves LV1 around three years ago. In two hundred-plus shows during that time, DiGiGrid products have never let me down.
I use the DiGiGrid IOS for front-of-house it’s the best option available with eight inputs, eight outputs, two headphone outputs and AES. It’s ideal for PA feeds and some local inputs like talkback and playback from a video stream for the show. I love the preamps very transparent and clear.”

Heckers, whose career credits also include Liza Minnelli, Melanie and Randy Newman, owns several DiGiGrid products: “I actually have three Waves LV1 setups for different tours. The Kings of Floyd gear stays in the truck but I use a similar setup for other tours.
I’ll be upgrading my IOS’s to IOS-XL as soon as I have a break in the current Kings of Floyd tour. I also use a DiGiGrid MGB (coaxial MADI interface) on another tour – this is my newest setup that deploys a DiGiCo rack on MADI to MGB on FOH and has an IOC at FOH.”

On the bottom screen the « desk » and on the top the desk « screen » showing one of the 8 possible plugs per channel.

With a strong reputation and more than twenty-five years of experience that has encompassed ten major world tours, Howard Heckers has heard and used almost every available console on the market but considers that using DiGiGrid with Waves LV1 is the option that best suits his requirements. He’s also an admirer of the units’ durability, describing them as “rock solid”.

DiGiGrid’s european product specialist Michael Maurer.

Kings of Floyd’s connection with DiGiGrid extends even beyond its use by their renowned FOH engineer.
When the demands on Howard Heckers’ time recently resulted in the need for a deputy to cover some dates on the band’s current tour, they called on the services of none other than DiGiGrid Product Specialist, Michael Mäurer, to take the hotseat.
An accomplished sound man in his own right, Mäurer enjoyed the experience adapting to the setup was certainly not a problem!

dlive loves the ice in Switzerland

An Allen & Heath dLive mixing system is used for one of the most successful ice-skating gala events in the world, Art on Ice, which celebrated its 25th anniversary this month with a series of shows taking place across Zurich, Lausanne, Basel and Davos.

Combining live performances from internationally acclaimed artists, world-class dancers and figure-skaters, including the 2018 Gold Olympic medallist Alina Zagitova, Art on Ice offers a unique and immersive storytelling experience.
Produced by Swiss AV production company, Habegger AG with Session Pro helping to supply gear, the full setup featured a dLive S7000 paired with a DM64 MixRack, fitted with a superMADI card for multi-track recording and a Waves V3 card for external plugins.

Operated by long-time A&H user and FOH engineer, Sascha Kohl, dLive was used to handle all sources including the musicians, vocalists, presenter and playback.
The nature of the venues presented some challenges, as Kohl explains, “As the main part of the hall is a very large, highly reflective sheet of ice, I was never able to get into a really good listening position, which made getting the mix perfect a little tricky at times.
As the PA was set up for the crowd, having the possibility to do the VSC on my laptop, via dLive Director, and walk around the venue was absolutely essential.”

Kohl is also quick to praise dLive’s easy scene management, including the simple to use ‘relative’ and ‘absolute’ update functions, and the MCA control introduced in firmware V1.8, which allowed Kohl to easily run the entire show via one surface.

“The music, video playback, band, singers and presenter work seamlessly together and it’s great to have one system that can handle anything thrown at it,” Kohl adds.
“I’ve been using dLive since the very beginning and before that I was a long-time user of iLive, so I’m totally into A&H consoles. dLive’s workflow is just quick and easy to use, and I love the additional DEEP processing available, such as the OptTronik, 16VU and 16T.”

The Big Blue dives into hyper realism: Part2

Seb & Max in front of the SD7, and on the right Fred Bailly of L-Acoustics. Just a few minutes before BlackOut and Go Cue 1!

May 11th. Everything’s in place. Long months of thorough work are leading to The Big Blue in Live version. One of the essential shadow men, Jean-Phi Schevingt, shares with us his passion for this project. Add the L-Isa full configuration and our listening impressions and you’re ready for a No Limit dive! Let’s go.

Jean-Philippe Schevingt, the goldsmith of sound

SLU : How did you come to join this team?

J-Phi Schevingt in front of his MainStage deployment. The beard has turned white, the glasses have appeared but the experience is only growing…

Jean-Philippe Schevingt : Most simply, I was called by Romain who quickly understood that it would take two to find and rework this amount of sound data.
I started working on the first patches in January when I was able to get my hands on all the machines, and I saw how long it was taking.
I myself quickly understood that until the last moment I was going to be occupied by this task and that I would never have found the time to work on my scores.

SLU : Tu devais aussi jouer ?

Jean-Philippe Schevingt : Of course, we should also have been the two keyboard players of the orchestra with Romain but I preferred to call Eric to tell him that it was better that I remain at the disposal of the musicians in order to put them in the best conditions to play.
As in addition, as I was the one who programmed everything, even in terms of assignments of sounds to the different MIDI controllers, it was better that I stick to do that. And then, to play this soundtrack you have to know how to stick perfectly to the score and the click track, by placing the note on the fourth sixteenth note of a time, and I’m not good enough reader to do that (laughs)

SLU : It seems that Eric Serra (the composer, Ed.) keeps everything!

The TX816. The brute force of the time, brute… and cumbersome; 0)

Jean-Philippe Schevingt : Lucky enough! He preciously kept all the Sysex files and the backups of his synths, I was able to have elements, but to read them it was necessary to refurbish old Macs with old OS to manage to use the old software of 1988 and the Sysex of TX816 (Racks containing eight FM synthesis cards, Ed.).

Thanks to that, I was able to program virtual FM8s from Native Instruments. You should know that 80 to 90% of the Big Blue synth sounds come from the Yamaha DX7 with a lot of layering. Hats off anyway to MOTU for their backward compatibility.
I have never seen this. I don’t know any software that knows how to open a session that is 30 years old. Neither ProTools, nor Cubase… Look at the date of the last modification of the opening credits. February 9, 1988. You double click and after being told that the software does not find Eric’s MIDI environment …

More than a long speech, for our readers who are less than 30 years old, this is what a Mac SE screen looks like, barely larger than a CD and monochrome case. It’s from Performer 1, and it’s the opening track session at the start of the movie, the Big Blue opening. Track two is the tambourine making the “fffrr” sound. We also see the locators on the time codes where the names appear in the credits for the first audio meetings with the image. Only the reverb “rolling” tracks are missing and it feels like it!

SLU : Et en dehors de Yamaha ?

Jean-Philippe Schevingt : We had to take sounds from the Emulator 2, the Akai S 950, the Kurzweil 1000 PX or the Roland MT32. Once sampled, all of these samples and virtual synths are managed by Apple’s MainStage host software. Two double redundant configurations. A first one contains all the sounds that will be played by the two keyboard players, by Eric and by the sax which also has a keyboard.
The second one contains all the drum and percussion sounds but also all the samples that will be played by the two drummers. The whole set up fits on 4 Mac Mini, big quad-core models with a lot of RAM. Add to that some MADI cards and I’m able to deliver to FOH the 64 outputs they asked me for: 32 for keyboard sounds and 32 for drum sounds.

SLU : You were mentioning redundancy…

Emergency requires, the MadiBridge is placed under the eyes of J-Phi who also has 3 mice. A man who doesn’t get confused with so many mice is called a “polyrodent”, LOL.

Jean-Philippe Schevingt : Everything is mirrored and ends up in a RME MadiBridge that I have right in front of me. If the main one ever creates a problem for me or generates a noise, I switch to the spare one.

SLU : Are you sync to the Time Code too?

Jean-Philippe Schevingt : No it’s all done manually, I don’t have the need to be hooked to it. There was a point when I might have needed a MIDI clock to follow the tempo of toms with a delay played by Eric, but not for the rest.

SLU : MIDI stands up firmly despite its 35 years of age…

Jean-Philippe Schevingt : On long cable lengths like we have here, it is still the most reliable. 15 meters without amplifier, converter nor expander, nothing that could interrupt the signal. I am installed right where it is needed for that.
I had too many problems with USB, especially when you have a lot of machines and where an IP conflict causes you to lose a keyboard or a pad. I have my 14 MIDI cables coming from the different controllers on stage to two MIO Connectivity interface racks which send the orders to my two MainStage.

An idea of the configuration thought, programmed and exploited by J-Phi Schevingt.

SLU : So tonight it’s gonna be Next, Next, Next (smiles)

Jean-Philippe Schevingt : Exactly, but I also monitor the progress of things because the boys are so busy with their two hands and feet that sometimes it’s me who brings them layers or remotely puts their pedal down so that the sound really comes from far (laughs). They are real professionals, but they have so much to do …
I’ve been on it all day and 6 days a week since February 23rd, I’ve only done that, I know what I’m talking about! I also made a technical rider with the time cues. Whether to reboot or move something, I know when to do it.

The two MIDI interface racks on the left and the 4 mini macs and their RME cards on the right, all within easy reach.

SLU : This might sound like a silly question here, your configuration works perfectly at the moment we are talking (the morning of the concert day, Ed.). You won’t touch anything anymore from now on, or will you restart the whole before the show tonight?

Jean-Philippe Schevingt : I’m going to turn everything off, let it cool down and, one hour before the show, I’m going to restart everything and take a tour of all my keyboards. And I will test my spare set up too.


SLU : It could be tempting, though…

Jean-Philippe Schevingt : Some guys never touch anything and it can work that way, but IT can reserve some weird surprises. A computer will stock material into its RAM modules, and when you switch it back on again, if it doesn’t empty its buffers correctly, it will block part of its RAM and might work in an awkward way.

SLU : MainStage and you…

Jean-Philippe Schevingt : It’s an old story. I set out on the road the first tour for Calogero (French singer) with in 2007. I went to Ireland to get the first Logic Studio box ever delivered there. Two years later, with Ivan Cassar (French composer, arranger, producer and piano player), we set up the first full virtual show in the world in stadiums for Mylène Farmer (French singer). As everything was virtual, we had equipped 6 Mac Pros with 8-core, 4 internal disks, we had consolidated everything (We are at the level of aviation industry redundancy, Ed.).

Julien Carton’s keyboards with the Native Instruments / Nord pair, above which we find the tablet for the score and in between with the Gaumont logo, the video monitor in which the beat is displayed.

To make you understand the power of MainStage, for The Big Blue and to be relaxed, we should have found around 20 DX7s and at least 6 fully fledged samplers.
The choice is quickly made. We compared, in Eric’s studio, the sound output from the rack TX816 and FM8 plugs and it is the latter that win, thanks also to more modern converters.
Their ease of use allowed us to very easily reconstruct the layering with the slight tone shift used on the 1988 version.

SLU : How drum sounds are made?

Jean-Philippe Schevingt : With Native Instruments Battery 4. I also use on stage master keyboards, Complete Control from Native.

Loïc Pontieux’s drum kit with a lot of sticks, looking brand new indeed ;0)

SLU : I see red gear everywhere, though…

Jean-Philippe Schevingt : (smiles) These are Nord Stage, because the 88 notes model from Native (also with heavy response keys), has no pitch bend, and our musicians use this all the time, for example for Pan flutes.
It’s a shame because the next model that will be released soon has knobs. It’s no good luck. They had made the choice at Native to replace them with ribbons like the “Touch Bar” of the Mac, but that did not work with the musicians because it is pretty, it is modern, it is fun but …

SLU : Can you get these melodies out of your head…

Jean-Philippe Schevingt : No I can’t (smiles). I have been living with them day and night for several months. I will happily dive into Eddy Mitchell’s tour next week (French singer). That said, I love this soundtrack, and as I said to Eric, after seeing the movie in cinemas when it came out and discovering sync to music on screen, a sync such as even uninitiated people notice it, that contributed a lot to my desire to do music computing.

The Grande Seine as seen from the stage, a magnificent hall which adds to the Parisian offer. 4000 seated or 6000 with the pit, there is plenty to do!

In the months after the screening, I bought my first sequencer, my first computer, my first machines, and started programming. So it’s funny to find myself 30 years later in this position and to have the chance to introduce him to current toys.

SLU : This soundtrack doesn‘t seem easy to play…

Jean-Philippe Schevingt : For us and the musicians it is complicated because in a song, Eric is able to repeatedly change the tempo and the number of beats in the measures to catch up with the image. Musically this is not that obvious, but to play on stage is really not easy.

The screen with its L-Isa Focus deployment. Well hidden behind and from left to right we see Ben Rico facing his SD7 taking a pic of Jean-Marc Barr on the screen, then Romain Berguin in front of his ProTools, Jean-Philippe Schevingt and his MainStage and all right the flight-case of Lucien Viendras, in charge of acoustic instruments.

SLU : Too bad you’re hidden behind a curtain with Romain…

Jean-Philippe Schevingt : But we should have been in front, Eric wanted it and until two or three days ago, we should have accompanied the musicians with our gizmo kit.
But you have to be able to act calmly when the need arises, without attracting people’s attention because we go around the desk and tinker with something.
I am frequently on stage as a keyboard player with the responsibility sometimes of a ProTools, and my obsession is to stay clean in front of people, to react without being noticed.

May 11th

For the first time, we enter the Grande Seine and as always behind the scenes. The huge micro-perforated screen makes it possible to follow the film which now takes place at the same time as the musicians rehearse, but upside down. Seeing Rosanna Arquette with a head 3 meters high let see the magnificent green of her eyes… but let’s move on.

The movie as seen from backstage, with the 5 base arrays of the L-Isa deployment.

The Focus deployment by L-Isa is also a pleasure to see and mainly to listen to. There are diaphragms and drivers indeed, and with K2 we are in 3-way on the three central points, the 3-4-5, with 9 enclosures per array. When there is space, this Focus configuration seems to be the perfect solution to build muscle in the center where naturally there are sources rich in bass and dynamics. Another advantage, these three lines of K2 being very close to the subwoofers column, the connection works well.

The strength of L-Isa in a plot. The percentage of the audience covered by a coherent and consistent signal is maximum, especially since this hall opens exactly like an horn speaker. Only the first rows suffer a little.

Lines 2 and 6, always behind the screen and of 12 boxes each, remain in Kara just like the 1 and 7, of 9 elements each, visible this time by the public because hung on the widest part of the room and twisted inside.

The surrounds, made up of two lines of 9 Kiva II, are placed at the top of the stands in the distance. At the end of the stage, 6 Kiva II pull the image down and give a little sound to the front rows.


When you listen, you immediately notice that the stage volume and the screen trap the infra bass frequencies and that the K2’s treble drivers are playing with the screen. It bounces in a dry way. At the bottom of the screen, hidden by a black hanger that surrounds it, we find Ben Rico and his console, Romain Berguin and his ProTools, Jean-Philippe Schevingt and his half computer and half synth machines, accompanied by the backliner in charge of the acoustic instruments and of the technician in charge of the video server. Add to this a big pack of LA12X controllers (and only 12X), even for Kara or Kiva. Hats off to Dushow, the rental company.

The engine room with in particular two L-Isa processors and their two ADI-6432 converters from RME and 21 LA12X controllers. Above, the three Focus lines in K2 and the two less stressed lines in Kara. The KS28s column in cardioid mounting is very well positioned behind the K2s.

With the hall still empty, the sound is naturally a little dull on the last octave, while the bass and infrabass, although present and precise, are a bit long. Other details would also call for a comment, but as with a full room and thanks to Max and Seb, they will disappear almost entirely, no need to waste bits.

The response of K2 is averaged over the black line. 6 dB of treble compensation was required to make it thru the screen.

On the good news side, the bass gives chills because it makes you rediscover the soundtrack. The kick drum, Eric’s bass, the synth layers, and some notes that get infra-infra in 40 Hz, bring a natural and a base that the poor serious freeze-dried and dripping usual bass response from a standard cinema cannot reach… The rehearsal runs smoothly at 90 dB(A), a perfect level which will only very rarely be exceeded the same evening.

Eric Serra in full performance, with more light than in reality in this photo, and still as good on his bass.

Seb had to rework his spatialization as planned, especially the extends which are not behind the screen and cannot be easily transposed into the room.
The low end of the spectrum, which cannot sound the same way between a small studio and a large room, is also set rightly with a level of reverberation adjusted to that of the Grande Seine.
The end result is as beautiful as a glossy Marcoussis (Home town of L-Acoustics, Ed.) brochure.

The musicians step on stage and grab their instrument, Eric Serra arrives to the applause of an audience obviously already under the spell.
The discreet lights, but how could it have been otherwise not to pollute the screen, bring their own atmosphere.
It was the ultimate difficult lighting project here, but LD Dimitri Vassiliu came out of it with his usual sheer elegance and experience.


The student bulletin of Menelec Maxime for this L-Isa operation ;0). Everything is almost at a standstill.

The 7 musicians come to life at once, guided by an invisible half-ProTools half-Berguin conductor and the magic works instantly. Implacable.
The credits scroll and we are all taken by the same pinch. The Big Blue comes back to life before our eyes and especially in our ears but better, so much better than in a standard cinema.

The sound image overflows widely from the screen and saturates our poor stereophonic spirit, soon stereophobic, with happiness.
The magnitude, the precision, the breadth of the spectrum, the dynamics, the beauty and the localization of the sounds, everything contribute to dress up the image, and this soundtrack which has already done so much for the movie, steels the show for the first time for itself.

The musicians’ play with their own timing, the new quality of the sounds, the mix reworked for Seb’s room, the far from obvious settings of Max, Ben’s “catering service”, the power at the top of K2 which has finished to perforate the screen, L-Isa who with the Focus deployment is finally ready to tackle the variety and the shadow work so important of Romain and Jean-Philippe, all these make this movie-concert a real concert-movie and above all, a rare moment when my eyes sometimes had a strange lacrimal reaction. I must be allergic to good sound and talent ;-).


Renan Richard, Eric Serra and François Delfin playing live the ambient music taking place during the spaghetti party in Enzo’s room in the movie. And they’re having fun indeed.

A few months before the entry into force of the “102 dB(A) limit” French Decree, we enjoyed 90 dB(A) and 101 to 104 dB(C) remarkably well achieved, without ever wincing or putting ear-plugs, but with the breadth and impact essential to any show. Wondering what the extra 15 dB is for.

This was a real concert, and one of the most difficult for the musicians. Hats off to you, guys!

From left to right Marcin Zimny, Tommex Commercial Director, Marzena Wójtowicz, Tommex Sales support manager and Luca Ombrati, RCF International Sales Manager.

Tommex’s Commercial Director, Marcin Zimny, stated that the move resulted from changes in the ownership structure and distribution strategy of their existing long-term loudspeaker partner. “This meant we were looking for a new partner with a high-quality installation range, that could complement our portfolio; RCF provided a great opportunity and was an exact match.”
“The combination of 70 years of RCF history with 30 years of Tommex provided a compelling partnership”, he said. Over the years Tommex has equipped many sports venues from stadiums and sports halls, to entertainment arenas, swimming pools and ice rinks. They had also worked extensively in theatres, operas and culture houses, concert halls, schools and transportation hubs. As such, RCF was seen as a perfect fit, and would create synergies with other brands in their distribution portfolio.

Confirming the decision, RCF International Sales Manager, Luca Ombrati, stated, “We were one of the few brands able to fill all the missing product lines in Tommex’s product portfolio.
After negotiation I accepted their proposal because until then RCF had only been successful in the ‘entertainment’ market segment (Pro Audio and MI), thanks to our partner Arcade Audio, and they will continue as our exclusive distributor for TT+, Pro, Live, Mixing, Recording and Transducer product lines.

“But for RCF this provided an excellent opportunity to develop the ‘Installation’ market-segment in Poland, represented by a well establish distribution company in the specific field.” One range that looked particularly attractive to Tommex, he continued, was the new Business Line of products. “We also see great potential in the Compact and Compact-M series, the P series, the entire commercial sound catalogue and the DXT3000,” continued Marcin Zimny.
The company has wasted no time in marketing the brand. “We have already announced this to our customer base on social media, the trade press and other portals. We will introduce it further during trade exhibitions, seminars and demos.” Leading the sales mission will be Tommex Commercial Director Marcin Zimny, who will be personally responsible for the development of the RCF brand in Poland.

In closing, Mr Zimny said, “Our customers have been positively surprised and extremely excited by the news [of the RCF brand acquisition]. They are delighted that we can offer such great quality systems and are able to expand our product portfolio to offer such a wide range of systems and possibilities … quickly, and with excellent product availability and support.”
Luca Ombrati concluded, “We are confident that Tommex can develop this specific part of business for us and look forward to a healthy trading partnership.”

Modulo Pi unveils KineMotion at ISE 2020

At ISE 2020, Modulo Pi, French manufacturer of media server for audiovisual applications, unveiled its latest innovations, with interactivity and immersive experiences in mind.

On their stand, ModuloPi introduced KineMotion, its new optical tracking module for interactive installations. Basically, the system makes it possible to follow objects or artists on stage, to bring interaction between image, light, sound with moving objects or performers.

KineMotion

Available as an option for the Modulo Kinetic media server, the solution includes a software to install on the media server, beacons that will be installed on the object or the artist to track, as well as a calibration kit including a rod and a square. The user will be offered to use Optitrack optical cameras, compliant with the KineMotion solution and with other tracking solutions.

La démonstration comprenait un suivi temps réel du véhicule, avec mappage vidéo et générateur de contenu, ainsi que des vidéos lues en arrière-plan. Au premier plan, l’interface de démonstration créée via Modulo Kinetic.

The receiver allows you to connect up to 8 beacons, which allows to follow sceneries with complex shapes, or to offer high-precision tracking with a performer.

On peut voir ici deux caméras OptiTrack pour le suivi de la voiture, et l’un des vidéoprojecteurs utilisés pour le mappage vidéo. La caméra NDI servait à renvoyer le flux vidéo dans un autre serveur Modulo Kinetic de démonstration.

To demonstrate the power and responsiveness of the solution, Modulo Pi team created a show on their stand, consisting of a clever mix of real-time interactivity with KineMotion and display of pre-rendered contents via Modulo Kinetic.

L-ISA

At the same time, Modulo Pi introduced its new connection plug-in for the L-ISA immersive audio system from L-Acoustics. L-ISA is a solution offering 3D spatialization of sound effects, or other audio track, used during a concert or in an immersive audio installation.

The Modulo Kinetic media server can now connect with L-Acoutics software, the two solutions can interact bi-directionally, thereby creating accurate immersive audio-visual experiences.

KineMotion is L-ISA certified as well, and can therefore be fully integrated to freely use the objects tracking in the 3D soundscape. When mixed with Modulo Kinetic’s real-time generative content engine, and the L-ISA immersive audio solution, KineMotion offers a new range of tools for creative people in love with interaction and movement.

One of the main goals of this all-in-one solution is to reduce the latency by avoiding the positioning signals to pass through several processors or interfaces, thus bringing precision and increased responsiveness to the movement tracking. By limiting the number of required devices, Modulo Pi offers a simplified implementation, thereby reducing the overall cost of the system.

A demonstration of the tracking responsiveness and accuracy can be seen here

Yamaha and NEXO Cancel Participation In PL+S 2020

Following the postponement of this year’s Prolight + Sound exhibition, due to the spread of Covid-19, Yamaha and NEXO have taken the decision not to exhibit during the show’s revised dates.

Jean Mullor

Nils-Peter Keller

In a joint statement Nils-Peter Keller, Senior Director Pro Audio & AV Group, Yamaha Music Europe GmbH and NEXO CEO Jean Mullor have said, “Both Yamaha and NEXO fully understand the decision by Messe Frankfurt to postpone this year’s Prolight + Sound show. The spread of Covid-19 is a complex, challenging and evolving situation and our primary consideration is for the welfare of both show visitors and event staff.
“As two of the leading brands in the professional audio industry, many staff and customers of both companies will be gearing up for the busy outdoor festival season during the show’s revised dates at the end of May. Therefore, it is with regret that we have now decided not to exhibit at Prolight + Sound 2020.

“Both Yamaha and NEXO are naturally very disappointed that we will not be present at the show this year and we look forward to an opportunity to return in 2021.”

DiGiCo Consoles For 2020 Hot Halftime Show

A pair of DiGiCo SD5 consoles handled front-of-house mixing for the Latina-American Super Bowl performances by Jennifer Lopez and Shakira, while two Quantum 7 desks in monitor world were plenty for the 150-plus outputs for the singers, musicians and dancers on stage.

Super Bowl LIV was a truly Latina-American event: Bronx-born Jennifer Lopez headlined the halftime show and Columbia native but Miami Beach resident Shakira shared the main stage, while New Mexico native Demi Lovato sang the National Anthem. The 12-minute extravaganza, watched by over 100 million people, garnered rave reviews for its showmanship but also drew plenty of kudos for its sound.

A pair of DiGiCo SD5 consoles at front of house and a pair of DiGiCo Quantum 7 desks at monitors were the crown jewels atop a custom JBL sound system, comprising 18 1,500-pound carts on the field and 14 flown line arrays. All of the gear was designed and brought in by ATK Audiotek, which has been the halftime event’s sound-reinforcement provider for nearly two-dozen Super Bowls now.

“For me, the SD5 is still the fastest-workflow console ever,” says ATK Audiotek Project Manager Alex Guessard, who also mixed the live sound for the show—alongside the Rolling Stones’ longtime FOH engineer, Dave Natale and designed the entire sound system, which was used for the pre- and post-game entertainment, as well as the halftime show.
“I set the two SD5s up so that we had mirror images of both the worksurface and one console as the A engine, so in the unlikely event that we had a failure on one console, the other was ready to run seamlessly.” Needless to say, there was no need to take advantage of that redundancy.

What the show did leverage, however, was the SD5’s superb input capacity, which Guessard says managed the complex show’s 60-plus input channels, including vocals, instruments and Pro Tools outputs, with ease: “It was flawless, and the SD5 is so easy to configure.
For instance, I used the assignment buttons on the left of the screen to toggle between the head amp, filters and auxiliary, and the moves were quick and easy under pressure.”

The event’s massive Dante network was “fed from the MADI on the consoles, and signals were eventually routed via AES to the amplifiers,” Guessard explains. Each console also had two DiGiCo SD-Racks of its own, allowing them to operate independently.

The monitor world

Over in monitor world, Tom Pesa and the monitor crew had to manage upwards of 150 wireless beltpacks for vocalists, musicians and dancers. He also used two consoles, both of which were Quantum 7 desks. They began working on the show at two rehearsal locations one offsite and one onsite which necessitated the need for two consoles to be available as the complex production came together. Once the show was ready, Pesa, like Guessard, kept the second desk online as a backup.

“Instead of having the B engine as the backup on one console, we’d have an entire second console as our mirrored B engine,” explains Pesa, who was working his 24th Super Bowl halftime show. “It’s overkill, but it’s also the Super Bowl.”
The output of the console went to a combination of in-ear monitors 120 of them for dancers alone, who rely on them for click tracks and cues and to a dozen ATK Audiotek LM3 wedges around the stage. Pesa says the Quantum 7 managed all of that easily, using only onboard processing.

“I lean heavily on DiGiCo’s onboard processing; I almost never need external processing, especially since Quantum came along,” he says. “That gives me so many onboard options for limiters, compressors and EQ, and I can easily customize each snapshot for each artist as each pass goes by. There’s so much available to let you make each artist sound exactly the way you want them to. It’s all just there at your fingertips.”

The Quantum 7’s assignability was also called upon for this show, as Pesa was able to set up an entire separate section of the console customized for Ramon Morales, Shakira’s longtime monitor mixer. “I could literally create an entire section for him with Shakira’s inputs for vocal channels and effects returns, and any other control group needed to lay down as a VCA to control her Pro Tools level, all in one bank,” he explains.
“So I could do what I needed to on my side of the console and Ramon could have everything he needed laid out right there in front of him. The Quantum is a big leap forward and I’m really impressed with how many new features there are with the new firmware, like Mustard. The console just keeps getting better.”

Tom Pesa, the ultra skilled monitor engineer with 24 shows in his pocket

Super Bowl’s halftime shows are a marvel of tightly packed bombast on a precision schedule that a field marshal would admire. “It’s all over so quickly,” recalls Guessard, who was working on his third Super Bowl halftime event.
“We had six minutes to get ready as the football players were leaving the field and the stage was coming together, then a 12-minute show, then six minutes to get ready before the teams came back.
It’s a huge adrenaline rush no matter how many times you’ve done it, and it takes an insane amount of coordination. You need the tools you’re using to be perfect, and that’s what the DiGiCo consoles are perfect.”

Netgear M4500 Switch series: The broadband backbone for IP video networks

In this latest edition of the ISE show hosted in Amsterdam, Netgear, a well-known brand of Wi-Fi access points or other powerline adapters, was on the show floor represented by its professional division.

The Netgear team shared a stand with other manufacturers, members of the Software Defined Video over Ethernet (SDVoE) alliance, the organization behind the solution. If you’ve never heard about it, SDVoE is a suite of protocols implemented and available in compliant devices, allowing users to transmit uncompressed video streams over IP networks in an easy way. The hardware offers connection, transmission and reception points, but the routing of the video stream is software only, which offers greater flexibility to the users.
The SDVoE alliance announces zero latency for the transmission of the video streams within the IP network, and promises unrivaled performances when it comes to many video streams, thereby simplifying the wiring and the number of devices in the video chain. Furthermore, a fully IP based video system reduces the number of conversions required for long distances and site interconnections.
The SDVoE protocol allows the transport of an uncompressed video stream using a 10Gbps link. It is quite easy to understand that if you wish to transport several dozen of video streams on the same network, the size of the backbone (the network infrastructure) becomes a key element.


The Netgear M4300 switch series, already available on the market, offers a wide range of models, with 10Gbps ports on RJ45 connectors or 40Gbps ports on QSFP+ connectors. But when the number of video streams requires a more powerful backbone, very high capacity core switches become the only choice. This is why Netgear, one of the founding members of the SDVoE alliance, introduced at ISE their new M4500 switches series, in complement of the existing M4300 series.

These switches provide the necessary processing power when several hundred Gigabit of bandwidth are required for the latency free transport of video streams. Directly inspired by Netgear’s data center switch design, these switches are preconfigured for an easy interconnection with other SDVoE compliant equipment, but the devices can be used for other audiovisual applications as well.

Netgear M4500-32C Switch

The M4500-32C model offers 32 100Gbps ports.

Netgear M4500-48XF8C Switch

The M4500-48XF8C model offers 48 x 10/25Gbps ports, and 8 x 100Gbps ports.

The two models introduced at the show, respectively M4500-48XF8C and M4500 32C, will be used to interconnect the M4300 switch series as access switches, where SDVoE video encoder/decoder will be connected via network cables. 40Gbps links will be used between the M4300 and M4500 switches to create high speed links.

The M4500-48XF8C can also be used to directly connect video converters via a 10Gbps or 25Gbps fiber optic link. In this specific case, the device will be used as an access switch, and the M4500 32C model will be used as a core switch, creating 100 Gbps links between the two devices, thus making it possible to connect up to 640 devices on the same network

On the SDVoE stand, Laurant Masia, director of product line management, explained during a 30-minute session this type of applications. The presentation revolved around three main application axes:

– A stack-based solution: The switches are combined with each other and become, from a user point of view, a single switch, with high-speed links between the switches, to simplify management.
– An aggregated link-based solution: several links between two switches are combined together to create a single very high capacity link. For those used to 1Gbps networks, this technology offers bandwidth between switches that can make your head spinning!
– A VLAN based solution (virtual networks within the physical network). Some of the links between transmitters and receivers are placed in virtual networks, to provide interference free communication between the devices which are included in the same virtual network (see illustration below).

When looking at the announced bandwidth, it is obvious that these switches will be able to cope with large-scale video over IP applications.


switches-netgear-m4500

The VLAN technology used to transport SDVoE video streams (extract from Laurent Masia’s presentation). The example above represents isolated links of 4x100Gbps between the access switches and the core switch!

The SDVoE protocol will also be able to rely on such network architectures to offer unlimited video matrix possibilities. As an example, some of video streams might be sent to several destinations. If you are not familiar with network technology, this communication method is called Multicast, a one to many communication scheme, where the destination specifically request the video stream it wants to receive.

Multicast is based on a mechanism which did not take such bandwidth into account when it was first proposed (1986). Named IGMP snooping, this solution allows multicast streams to be sent to those who have requested it. Unfortunately, and in some specific cases, certain equipment or certain links may be completely flooded by streams they would not have requested.
To overcome this problem, subnets can be created, and routed to each other via PIM (Protocol Independent Multicast) technology. However, the use of this technology requires in-depth knowledge in network architectures and does not always offer the expected result. But wait, Netgear offers now a new version of IGMP, simply called IGMP +.

This proprietary solution allows these constraints to be freed, and hundreds of AV equipment to be interconnected, by exempting users from using PIM technology, while using already known IGMP techniques throughout the AV over IP network. For those who have already faced this kind of problem, IGMP + is a real step forward for the simplification of audiovisual networks.

With this new range of switches, Netgear demonstrates its desire to position itself as a key player in the AV over IP networks. According to Laurent Masia, Netgear will present new models of switches at the Infocomm 2020 show, so stay tuned!
