The electronics involved consist of 43 samples (some of which are recordings made bySamuel Stoll, others taken from the internet), and pitch-shifts in the range +12/-12 (i.e.one octave up and one octave down). This all requires a close microphone andfootpedal e.g. Roland FC300 connected to computer. The left control pedal regulatesdownward pitch-shifts, the right control pedal regulates upward pitch-shifts. Samples andMaxMSP-patch are available on request.
