The Patch out on the LH is self-contained.
Believe it or not there is method in my madness, My hope was that someone may show me their examples of their stages to output so I can learn a bit from others.
RH side would have the ability to split signals, route stereo, Pan mono, mute, effect and then double back on ts self for an feedback loop arund the effects.
LH side, relatively minimal patching ability but CV control, yet Mix and output with monitoring all in one module.
I could leave out the level meters so it doesn't look like a Christmas tree ;-)
Enjoy your spare HP, don't rush to fill every last space, this is not like filling sticker books. Resist the urge to 'complete' your rack, its never complete so just relax.
