In his splendid review of the MatrixBrute for SOS (February 2017), Gordon Reid claims to have "created complex modulation signals that weren't routed to the sound I was playing on the MatrixBrute itself, but rather directed to the CV outputs and then on to other synths." How does one accomplish this? Every modulation routing I have created in the Matrix always seems to modulate the MatrixBrute itself, as well as anything connected to its respective CV outputs. How do I route such modulation signals through the Matrix to the CV outputs alone?
