A channel can be used as a low pass filter, as VCA or as a combiantion of both functions. Latter corresponds to the behaviour of acoustic instruments, where increase in volume changes the harmonic spectrum.
The CV input controld the gain in a range of -120dB to +3dB
In addition to the channels' direct outputs the module contains mix outputs. ALL provides you with the mix of all four channels, ODD with the mix of channels 1+3, EVEN mixes channels 2+4.
Per VCF/VCA channel: signal input, CV input, individual output
Mix outputs for all channels, odd channels and even channels
