Cinnamon

A voltage-controlled state variable filter with low-pass and high-pass (12 dB/oct) and band-pass (6 dB/oct) outputs. Cutoff takes a V/Oct input and an attenuated FM input, the audio input has its own gain, a DRIVE switch overdrives the filter's input, and two CHARACTER switches change the resonance response. At full resonance it self-oscillates, with phased sine waves at the three outputs.
