State Variable Filter
The Q107 Filter changes the harmonic content of signals to create new, interesting sounds. This removal of harmonics is the basis of subtractive synthesis. Frequency cutoff and the (Q) can be controlled manually and via voltage control by envelope generators, oscillators, the keyboard, etc. Control signals can be attenuated and inverted. Low Pass, Band Pass, Notch (Band Reject), and High Pass responses are provided simultaneously.

These merchants probably sell this module. Huh?
