Module is available as a DIY project only.
This Module is a prototype or in a concept phase.
3-input VCA
Based on David Haillant's "Simple VCA", I built this on a protoboard and used a nibbler to cut the aluminum front panel out by hand, because I am terribly impatient. The potentiometer is a slider for the same reason. The whole VCA and mixer circuit is a single LM13700.
He has boards available, and his module is only 4HP compared to this one's 6HP.
