Fantastic sounds. I built a feedback-heavy synth based on Reaktor Spark. I was disappointed to discover how difficult it is to anticipate the pitch of the signal, which limits its harmonic usefulness. For a sufficiently narrow band around each preset, including the frequency of the source waveforms, the map from those source waveforms' frequency to the output frequency can in general be discovered. But as you wander around the relationship can change wildly -- indeed, some output signals don't even have anything that sounds like a fundamental frequency. I wanted to program something that would manipulate the source waveforms' frequencies to automatically produce an output signal of the pitch a keyboardist had asked for. I think I could with sufficient time but it's a nontrivial problem.
