Performance Notes
The Macintosh audio outputs are sent to a good quality reverberation (with a reverberation time of about 3 sec), the ouput of this reverberation unit send to all the speakers.
To play the piece
Open the RHIZOMES-TR04.pat patch with MaxMsp version 4.
(or RHIZOMES-TR05.pat with MaxMsp 5)
Switch the DSP on.
Select the section 1 : you are ready, the musicians can start playing !
During the performance of Rhizomes, you should carefully follow the musical score and monitor the event sequencing. It can be necessary to resynchronize the score following system (in case of too many consecutive wrong notes from the musicians, for instance)
