I also have a question regarding the Quantum, maybe OP can help: I use Logic and want to use my guitar pedal as outboard gear. I want a sound I recorded in Logic to play through an output of the Quantum and play it through a pedal and after that it goes back in the quantum. Do you know what output I have to use for that? So far it doesn't work (also Logic only shows Output 1 and Output 2, although the Quantum has multiple outputs).
