RIPSNORTER is a analog synth, featuring Chris Kerry’s excellent Unison Oscillator, which include PWM on all waveforms except Sine.
The Oscillator feeds into a multi-mode filter that provides both Low-Pass and Band-Reject [Notch] outputs at the same time. X-Pan allows for a stereo signal path, with the Low- Pass output sent to one channel and Band-Reject to the other. There are plenty of modulation options which should allow you to create a broad range of useful timbres. The UI is slightly different from others in this range, in order to fit in a more comprehensive distortion set-up.
