How do you record digital to tracks 5/6 again? On my phone and can't open the PDF of the manual.
A dude is trying to get a patch so I need 7/8 open if he wants a mix of the 4 channels I'm recording right?
Should be I/O -> Input Sel: Digital.
From memory, the digital out will be exactly what you're hearing through the headphone output, regardless of what is going to 7/8. So 1) if you want something from the digital in as part of a mix, yes, you'll need to go to 5/6, and 2) don't switch the monitor between mix and DIN while recording, otherwise the digital output will change.
