I have this lying around for some time and now decided to upload it.
Based on the inFiltrator, this thing processes audio and at the same time acts as a synth triggered and controlled by audio in. Both pitch and envelope are controlled by audio, e.g. voice or guitar or drum loop or whatever.
You can mix the oscillator sound with the processed audio. You should adjust the "Gain" knob to fit your input source (for obvious reasons, this knob is not saved with the snapshot).
