Aikido

A quad dynamic VCA mixer, made with Casper Electronics: four channels with a LEVEL fader, a CV input and a MUTE button, chained from A to D into the MIX output. A side-chain envelope follower (FAST, MID or SLOW) ducks or pumps the channels, and a spectral follower (TREB, MID or BASS) gives a second envelope from the mix.
