Adam Holzman (Miles Davis, Mahavishnu Project) gives a quick demonstration of using the Moog Minimoog Voyager‘s Touch Surface CV outputs to simultaneously control two Moogerfoogers.
He does this using the Touch Surface CV outputs on the VX-351 Output Expander.
The X-axis CV is sent to a Mult, where it outputs two identical copies of the CV. One copy is sent through an inverting attenuator on a CP-251 Control Processor. Both CV are sent to the Mix inputs of the Moogerfoogers.
Since one of the CV’s is inverted, positive Touch Surface “X” values increase the mix of one. Negative “X” values increase the mix on the other.
