I'll check and advise. It gives you a "monitor mix" knob, so you can dial between input, and usb. The problem I had in the past when playing along with a track: If you monitor input, you hear it in real time, but not matched perfectly to the track you're playing with. If you monitor output it matches the track but is delayed from what you're actually playing (latency). So you have to dial it somewhere in this weird middle ground where what you hear sounds like a slapback echo, and what you hear both a "live" and a "track" that are just slightly delayed from each other.
It absolutely drives me crazy. I believe it has to do with the computer settings or whatever. Buffer size, all that stuff, I guess.
