This is a 3x3 matrix mixer: 3 CV inputs, 3 CV outputs. Each output has a dc offset control using push/pull pots so the dc offset can be turned on and off easily. Each output also has a 3 position switch that turns the output on and non-inverting, off, or on and inverting.
Typical setup: inputs set to an LFO, sample & hold, and the 8 step sequencer; outputs set to VCOs and VCFs.
Most of the modules have CV mixers built-in so this module is not needed for basic patches but can be handy for quickly switching
