1. Audio setup

2. Loudspeaker setup

The global system consists in:

  • PA System: 1 stereo system type L-Acoustics or equivalent. It must installed by a professional PA company so the design is adjusted to the venue for the best coverage in the public area.
  • Surround: a set of speakers placed around the audience and technically able to cover the audience area (the blue loudspeakers in the following plan). 6 loudspeakers minimum are needed. According to the venue, some extra loudspeakers could be needed in order to cover the audience area. Ideally it would be a 12 inches point source speakers (L-acoustics X12 or D&B E12).

Beware that amplification, EQ and Delay must be independent for each speaker.

  • Subwoofers: a subwoofer system, to cover the low frequencies of the PA system.

In addition to this setup, a speaker complement could be needed in case of particular acoustics conditions (f.ex front fill, extra-speakers on balconies). These choices have to be discussed with IRCAM Sound Engineer

3. Midi setup

1 Asparion midi controller. Preset file provided LiveRobin.aPres. Any midi controller with at least 11 controls will fit but you will have to reconfigure the midi mapping.

4. Software installation

We used Max 8.5.4 and Live (Ableton) 11.2.6 on Mac OS Ventura 13.2 with Apple M1 Pro 16 inch 2021.
Copy the folder Iridescence Janulyte onto your hard drive and add it to your search path in Max.
In Ableton preferences, make sure to use the external version of Max and not the Ableton bundle one.
