Trio + Stopped recording loops
I have had my Trio + for a few years now and have been happy with it. I recently added it to my Line 6 Pod HD500x setup with the Line 6 DT 25 amp. I was able to teach the Trio+ new parts and record loops, so everything was working fine. The other day I tried to record a new song and the loop appeared to record, but wouldn't play back. The bass and drum parts played back fine. I tried returning to some older songs and the old loops and bass/drum parts played fine, so the problem doesn't seem to be with playback, just recording new loops.
The Trio+ is in the effects loop of the HD500x. The guitar is plugged directly into the Trio+, the Effects Send from the Trio+ is plugged into the guitar input of the HD500x. The signal is passed through the HD500x pedal and preamp model and then passed back out via the effects send. This is tied to the Trio+ Effects Return. The Trio+ amp output is tied to the HD500x effects return and then passed out to the DT25 from there.
guitar -> Trio+ Guitar in -> Trio+ effects send -> HD500x guitar in -> HD500x Effects Send -> Trio+ Effects Return -> Trio+ Amp Out -> HD500x Effects Return -> HD500x L6 output -> DT25.
I have tried a factory reset of the Trio+, which didn't help.
I'm not sure what I'm looking for here. I guess I'm hoping that someone has seen this before and knows of some "Magic" that will return the Trio+ to full operation.
