Mescaline with Cocoquantus

They play together quite well.  In this patch I injected a coco oscillator into Mental, controlled a coco oscillator with a Trigger Sequencer gate, sent Pitch CV to Channel from coco castle, and triggered a Channel key from coco.  Audio from Mental and Channel is mixed in Befaco A*B+C, acting as two 2-input mixers, and sent to coco audio inputs.  We listen to coco outputs.
