Available as an assembled Module and as a DIY project.
This Module is currently available.
6 channel VCA/Mixer
This module is based around the SSI2190 6 stage VCA/Mixer. The unusual part is both the inverting and non-inverting inputs of the VCA stages are used, I wanted to muck around with sending the same signal to – and + inputs of different stages. Anyway, you have 6 VCAs all mixed into a single output.
These merchants probably sell this module. Huh?
