Low Pass Filter based on the late MS-20 VCF

This design is a classic, and many variations can be found across the internet as well as in numerous synthesizers and modules.
It is based on the late Korg MS-20 VCF schematics, which are a variation of the Sallen-Key 2nd-order filter.

The filter can be switched between Low Pass and High Pass mode.
