audio in: live input from voice and contact mic (attached to a steel brush)

math1: pitch detection of the steelbrush & voice; the voice gets the amplitude of the brush; amplitude effect (amplitude of brush sent to cutoff of filter with noise oscillator as input) + main mixer

math2: all kinds of different mathematical operations and algorithms (for the pitch and gate signals of the steel brush) + matrix (to make different connections possible between these algorithms)

Accent Gate: effect for the oscillator (with the pitch of the voice); this effect is a mixture of a gate, ring modulation and a filter

Agogo, Bass Drum, PerCuss C1 and PerCuss C2: different synthizers, mostly based on FM-synthesis, producing percussion sounds
