Magpie Modular repanel for Non Linear Circuits - Clump
Clump is a 4x4 CV controlled matrix mixer (MM). This means there are 16 VCAs on-board along with 4 mixers. It can be used as a regular mixer if you prefer. The gain pots can boost a signal to approx. 2x.
Each VCA gets a 1k trimpot to remove any offset voltages, each input gets a switch to turn off or invert the incoming signal and the pots act as gain pots with no CV patched in and as attenuators when CV is patched.
Purchase the PCBs from Nonlinear Circuits direct or from your nearest DIY supply hut.
