I think I know the answer to this (ie yes) but can I play say 6 tracks from a computer over USB and output them to various mixes whilst playing other instruments/mics through other channels of the QU, also outputted to various mixes as long as of course I don’t go over the total channel count?
So yes you can indeed do this, just go to the I/O patching screen and change the channel source of the channels you want to stream to to “USB B”
