MMM VCF (2024)

MMM VCF (M**g Multi Mode Voltage Controlled Filter) is a dual VCF having common controls for both parts.

Dual multi-mode transistor ladder filter

A classic transistor ladder filter with added High Pass and Band Pass modes (12 dB/oct) in addition to the usual 24 dB/oct Low Pass mode. It is dual filter tuned for stereo operation like the FUN VCF so the FM input and FM Input attenuverter affect both halves of the filter equally.

This 2024 “v2” update includes LEDs for the modulation CV levels, a slimmer 6HP form factor, and cool knobs.
