Electronics
Real time effects on the cello, triggered by the cello player with a MIDI pedal or automatically by following notes. The triggers are annotated in the score.
Audio Setup

You will have to add a reverb on the cello. Originally, it was an analogic Lexicon 300, but now you may consider using a numeric one in the console.
Diffusion Setup
Two options :
- 6 speakers for the electronic outputs, and cello outputs as well on speakers 1/2.
- 8 speakers : 6 for the electronics and two front speakers for the cello.
