Notes Voltage controlled, 24dB/octave steep, 4-pole lowpass filter based on the original US patent of the SSM2040 filter chip from Sequential Circuits' Prophet 5 Rev2.
FM is the cutoff modulation parameter with a voltage controllable modulation depth (VC-FM)

The gain is adjustable and until the 1h position (marked with "0dB") the filter is pretty smooth but above that the sound gets more and more overdriven. A VCA pre-filter makes the gain voltage controllable; alternatively you can route the VCA post-filter with a jumper.
