The record button does not stay engaged so I've taped the record button down for my sessions. The plastic clip that holds it down snapped at some point (not by me) and can be fixed, but the parts would need to be found. Otherwise, it works!
The 3 and 4 output ports do not export (3 does, but very badly), so you have two usable channels. You could write your 4 input tracks onto 1 and/or 2 as a compromise or just use 1 and 2. You could also rig the full 4 channels out by the headphone channel, though we're getting into some weird territory with that.
