MMM VCF (M**g Multi Mode Voltage Controlled Filter) is a dual VCF having common controls for both parts. Thus, it can be used as a stereo filter, or patched with different combinations of the available inputs / outputs. And all this functionality is packed in the compact 8 hp wide module.

MMM VCF has the famous transistor ladder core introduced by Bob Moog, but also features the added Band Pass and High Pass modes, not available in the original design. Those extra modes greatly widen the possible spectral modification of the input sound.

The module was carefully designed to have vanishingly small noise and bleed.
