Live and entertainingly noisy synthesiser, responding to multitouch and accelerometer control. You can control up to three independent voices at once. The sound synthesis method is GENeral DYNamic stochastic synthesis, as pioneered by Iannis Xenakis.
Imagine a set of control points (CPs) which together define the shape of a time domain waveform; with each new cycle through this waveform, their relative positions are updated using probabilistic distributions.
