Quick jam/demo of a prototype module I'm working on. It is a quad VCA module in 8HP based on Coolaudio V2164 with full analog signal path. VCAs are digitally controlled and the firmware (a work in progress) generates independent envelopes per VCA channel - supports trigger sequencing, direct CV control per channel, crossfading or triggering across all channels with a single CV, mixer solo/mute control by CV (with attack/decay on mixer mutes for smooth fades), MIDI control and more to come... Easy to use as a 4 to 1 mixer as all output jacks are normalled to a single output and each channel has a level pot (with 3x gain available). Input jacks are also normalled to allow signals to be split between multiple channels (e.g. to control multiple fx chains for same signal) This is a first prototype but is a lot of fun already :) Hopefully will be ready for sale in next few months..
