General Technical Notes

About Max ‘Projects’

They require a full installation of Max (free, see They allow one to modify parameters and are editable, so one can actually change the programming, but this is not recommended, except if one really needs it and knows what they are doing. Please refrain to do so, and if you it, let us know the reasons you had to do it, so that we possibly take your needs into account in newer versions.

These Projects, made on Macintosh, are most of the time compatible with Windows, but some libraries are sometimes causing authorization issues under Windows. This is in particular the case of the Ircam Spat (see, check here the procedure to authorize the necessary Spat objects under Windows.

Suggestion for audio interfaces


Suggestion for computer specifications in general

- Macintosh: Macbook Pro Intel Core i7 with 8 GB RAM, Mac OS X 10.4.x or newer
- PC: Intel Core i7, 8 GB, RAM; Quicktime for Windows, Windows XP or newer.

Suggestion for external reverberation

- for infinite reverberation, Lexicon PCM91
- for general reverberation, Lexicon or TC Electronic
Nota Bene: reverberations can be achieved with Max patches.

Suggestion for external harmonizers

- Yamaha SPX90 (discontinued) or SPX2000, Eventide Ultra Harmonizers series, or any high quality dual pitch shifting device.
Nota Bene: harmonizers can be achieved with Max patches.

Suggestion for MIDI

- MIDI interface: simple MIDI interfaces (e.g. Motu Fastlane or other brands) can be used.
- MIDI triggering: sustain pedal (for Max triggering) should be connected to the computer through a MIDI keyboard or a voltage-to-MIDI converting device (e.g. MIDI Solutions’ Footswitch controller, see

Suggestion for microphones

As much as possible, use headset microphones (e.g. for voice, flute, violin, viola, etc., and close miking, using directional, cardioid microphones for other instruments, in order to avoid feedback during performance.

Suggestion for audio mixers

- we recommend digital mixers (e.g. Yamaha), allowing 4 or more outputs. When analogue mixers are used, they should be used together with compressors and equalizers.

Suggestion for speakers

- any high quality diffusion system (e.g. Meyer Sound, Genelec, Amadeus, B&A, EAW, etc.)
