@OrlandoDoom: Right now it uses one footswitch to record a sample from the microphone into a buffer. Then another footswitch (soon to be three discrete footswitches in a single enclosure) changes the parameters which the two theremin antennas control:
MODE____LEFT HAND____RIGHT HAND
Two______Grain Position__Grain Length
Three_____Filter Reson____Filter Frequency
The granulator reads from a buffer, the volume and playback speed (pitch) of each grain are controlled by one of the antenna modes.
The position of the grains in the buffer and the length of the grains are controlled by the second mode.
The granulator is followed by a resonant low pass filter, so the third mode controls the frequency and resonance of that.
The main challenge was to find something that was highly playable instead of relying on LFOs or random generators for animation of the sound. Currently, the last input value from the theremin antennas is held by each mode when switching to another one. However I may add another pedal function which samples a hand gesture as sensed by the antennas, to be looped in one mode when switching to another.
The purpose of the instrument is for spoken word performance, a kind of vocal glitch/stutter machine. Documentation eventually, once the client makes a proper piece with it.
