First gig at Folk'n'Fusion festival

Tablet
Our first gig with the ilive system was at the two-day folk'n'fusion festival in hildesheim, last week of October. The festival has a small bar-stage and a larger ballroom-stage, with many bands playing. We play here every year, and this year we started on the ballroom-stage on Friday, then played a concert for kids in the bar-stage on Saturday and finally played Saturday night again in the ballroom.



Normally, we spend much time on our sound check, and then some more time on writing down all mixing desk and outboard settings. This year was different, we brought the mixrack as part of our backline and just placed it on the stage. We also brought our own cabling and microphones and everything was pre-programmed. From the mixrack, an 8 channel snake carrying left, right and aux 1-4, connected our system to the house system. Initially, there was some ground-loop problem which is irritating. A 2-channel transform-box was inserted on left and right, and we found some channels on the house snake that has significantly less hum for the monitors. Gijs and Edwin performed some tests on Saturday to figure out whether just a cable without the ground connected, or a DI with ground lift could fix the problem. It turned out that both solutions were not really working. Perhaps this wasn't a ground problem, perhaps it something else. The house system had problems with phantom power not working on channels 17-32, so perhaps something else was really wrong.

Our gigs were great. I just asked the band to play and used the tablet to set a room-mix (I always start with a rough room mix before doing monitors). All gain, channel-EQ, compression and gates were already programmed, so getting a main mix was easy. Then, I went on stage and fixed the monitors. This system is awesom :)

Next to doing our own sound, I help the festival by running sound in the bar. This year, there was an GL2400 mixing desk which I've used for the friday bands. On Saturday, our mixrack was already downstars for the kid-concert of the Gonnagles, and I decided to just use this for the other bands this evening. Doing sound for bands you don't know on a tablet is a bit scary, but since there was enough time for soundcheck, everything was great. I had a chance to actually use test the system in a new situation with various bands I didn't knew. One band, Evelyn Kryger wrote about their experience:

 "Während der nette holländische Tontechniker (selbst Musiker bei den Gonnagles) mit uns Sound checkt, räkeln sich eine Handvoll Festivalbesucher auf alten Sofas. Alles wirkt ruhig und entspannt, nichts deutet auf das hin, was eine Viertelstunde später auf einmal losgeht: Der Raum füllt sich schlagartig, die Luftfeuchtigkeit steigt unaufhaltsam und der Lärmpegel ebenso. Dann geht es los und was in den nächsten 60 Minuten folgt ist der Wahnsinn!!!"

Translated to English: "While the friendly Dutch sound technician did our sound check, a handful of festival-goers lounged at the old sofas. Everything is relaxed and nothings indicates what happens next: suddenly, the room fills up, the humidity and noise level rise. Then 'es geht los' and 60 minutes of madness follow!".

There must have been a lot of people in the bar, and I had a hard time walking around with the tablet. But, I was able to get trough and do sound from many different locations with my tablet. It was a wonderful experience, doing sound for (i guess) 200 people using nothing more than a tablet and pen. One thing was a bit scary: at one point the wireless connection dropped (I tested the 5ghz network, which is not ideal for going through a lot of human bodies) and I had to wait almost 2 minutes to reconnect to the ilive. Those seconds were very scary, but nobody noticed a thing. At any time, my normal laptop was connected to the mixrack using a cable, so I could have made my way to the stage and change things from there during those 2 minutes.

Dell Latitude XT tablet

This weekend, we bought a second hand Dell Latitude XT tablet! We will be using this as primary device for running the ilive editor. The tablet has a intel core2duo 1.33ghz processor and 3 gigs of ram. The screen is 12.1" with a resolution of 1280x800. The idea is to run linux with the editor on this.

So the first thing I did was install Ubuntu 10.4 (Lucid) on this, by using UNetbootin. I created a LVM partition of 40 gig with 32 gig for root and 6 gig swap (the complete hard disk is 120 gig). A minimal installation was chosen, so I could add only the packages we really need, keeping it nice and clean.

To install the X server, I install the following packages: xserver-xorg-input-wacom xinit lxde chromium-browser cellwriter. However, there are some additional things we need, for example some support for wireless lan. For this I installed the network-manager, bcmwl-modaliases and bcmwl-kernel-source packages. Then, there is a bug in the wpa_supplicant (version 0.6.9), so I installed the debian packages for 0.6.10 using gdebi and the AMD64 .deb files from http://packages.debian.org/sid/wpasupplicant http://packages.debian.org/sid/libpcsclite1 and http://packages.debian.org/sid/libssl0.9.8.
wireless-tools.

To install the ilive editor, I first installed libc-i386 and default-jre. Next, the editor is downloaded from the ilive-digital site and installed. Now we have a working ilive editor on a minimal linux configuration. But, it turns out that the linux version only supports online with surfaces!

So in the end, I installed windows 7 on the remaining disk space and it works like a charm. Hopefully, linux support for only mix racks will be added, so I can switch back to the linux version.

ilive IDR32, tablet, ipad, T112 demo

On Wednesday, Gijs and me traveled to Utrecht to meet Martijn from TMAudio. He responded to my e-mails inquiring about the possibilities of using a mixrack and tablet by inviting us over to play with the system. In three hours time, we learned a lot about the system and the possibilities.




Martijn is showing Gijs the ipad app
I must say, the ilive system sounds incredible and has real good potential. Martijn started of by showing us the T112 surface in combination with the IDR32 mixrack. All processing is handled by the mixrack and the surface is just one very big remote with many nice and shiny buttons and faders. Another way to control the mixrack is using a laptop or tablet using the ilive editor software. Also, there is an app for the iphone (iTweak) that has the ability to change basic channel levels and EQ. Finally, there will be a nice ipad application that has the ability to perform many of the editor functions. You want to use the ipad over the tablet because it has multi-input, which allows you to change the levels of multiple channels simultaneously. Martijn is working closely with Allen & Heath of the development of this app and therefor has a beta version of this app, allowing us to actually try it out. When the app is released (in 2 month time), it will be a really nice way of controlling the mixrack!


T112
The control of the mixrack is performed using a computer network connection. This means that you can also use a wireless router that connects to the mixrack and use your ipad and tablet from anywhere in the room or stage. The ilive surfaces are also connected using a cat5 network cable to the mixrack, but use a different protocol (ACE) which combines the control with some channels of audio. These audio channels allow the surface to receive the PFL and allows some local input/output (at the back of the surface). These audio channels are not possible when using the ipad or tablet.

In three hours time, Martijn showed us a lot about the system and we were able to make a basic mix on the T112, the tablet and the ipad using the multitrack we brought with us. It is a bit slower to build a mix from scratch then using a normal surface with faders and such. However, when the basic mix is made, the control is more then adequate to mix the rest of the show. In our case, we will need to perform a sound-check once (and spend much time on that to make it right), save it, and recall it whenever we need it.

We ordered the IDR32 with the PL10, which is a small controller you can connect directly to the mixrack. This controller gives us direct access to all channel levels and aux sends, in case something goes wrong.

I'll write much more information when we receive the IDR32!
