Thanks for all the feedback. I'd always see small output modules on the edges of most cases ad found them a bit lacking. I like the idea of using a mixer to properly EQ and blend signals together, it's why I liked the cross fader from the Rosie. Now, I'd like something a bit more involved with the rest of the case that instead allows me to push a few signals out while also letting me to route effects, filters, and modulation.
Thanks for all the suggestions; definitely have something to think over now.
