The LOPAG is the lowpass gate module for AE.

It is based on a Vactrol (like all good lowpass gates) and has two inputs: IN (audio signal) and TRIG. A pulse on the TRIG input opens the signal path shortly and via the characteristics of the vactrol the audio signal is filtered and attenuated in a plucked, percussive way. Additional GATE and CV inputs allow more control over the way the module works.
