Doepfer A-101-2V Vactrol Lowpass Gate (Vintage Edition)

A-101-2 is a vactrol based combination of Low Pass filter (LP) and VCA and was inspired by the Buchla module 292. The term "Low Pass Gate" was created by Don Buchla and stands for a module that can be switched between low pass and VCA. The control (manually and via external CV) is responsible for frequency in the low pass mode and for loudness in the VCA mode. Additionally a combined mode LP+VCA is available. In this mode the sound becomes more dull as the loudness decreases.
