Use insert type Y cables for stereo track outs. Same as for the CV outs. You can use plain TS cables for outs also but you won’t have any panning. You can use those for plugging to your sub phatty.
Yeah that’s a good idea. Just get 4 insert cables to the patchbay + the stereo outs. You could normal those to the inputs of your interface and still be able to insert a cable in the patchbay to send to the moog etc.
