Just a heads up, the Kaoss Pad Quad does not have midi -you’ll want midi to synch with your other gear. Get a KP3 or KP3+. User Accent was really really helpful and patient with me getting my KP3+ setup with midi so I could control it from my MnM which is really fun. Check YouTube for KP3/MnM examples (sounds like you may have seen them already). Maybe he’ll chime in here. Either way, if you PM me I can try to help you out. I intend to write up some rough instructions to share with the community but just haven’t gotten to it yet.

In terms of audio routing, I’m not sure what options you have, but yes, you could run it inline to your interface/monitors, etc. if you wanted or back into your OT, etc. It’s pretty transparent in my opinion so you shouldn’t have sound quality issues. Then again, I’m not very picky so others might find it unacceptable to run on the main mix.
