When recording direct over USB to my DAW with a backing track, I notice that I get some audio from the backing track bleeding onto the guitar track, if I'm using a high-gain patch. These artifacts are definitely noticeable at normal listening volumes if the guitar is silent during that passage and the backing track is near full scale. The strange thing is that it happens even when my studio monitors are powered off during the recording (so there is no sound being produced). Been trying to figure this out for a while now... Anyone have any ideas what might be causing this?
Some more details:
- MFC disconnected
- Axe FX main outs -> mixer -> studio monitors (tested with monitors powered off)
- DAW: Reaper
- No fancy settings or unusual preferences in Reaper. Just created empty project, imported media file for backing track, and added one track for recording guitar. Set to "IN 1". No buses or other routing.
- Mostly been testing with preset 024 (Friedman HBE), with noise gate turned off. The audio bleed is most apparent with high-gain patches with noise gate off.
Some things I've tried:
- Turned off "Send realtime sysex"
- Looked through this page: Help and answers - Axe-Fx II Wiki
- Contacted FAS support. Initially got suggestions that there could be crosstalk between the monitors and guitar pickups, but haven't heard anything else back from them after pointing out that I can reproduce the problem with monitors powered off (no sound being produced whatsoever during recording).
- Also tried unplugging cable from the guitar (so pickups are not in the equation), and I still get the bleed. It does go away though if I unplug the cable from the Axe FX instrument input.
- Can also recreate when plugging into the rear input, but the bleed is not as loud in this case.
