Display MoreI don't think, there is such a software issue in OS 8.710. Check your version.
If it's really OS 8.7.10, check:
- Is there still an input signal indicated by the INPUT LED?
- Does the issue affect all outputs or just one e.g. the SPEAKER OUT of a powered PROFILER?
- At which level is Volume Pedal (check on page Pedal Links)?
- Is there any error message?
The issue discussed here happens in OS 8.7.11 and the INPUT LED is completely dead. No error message. It happens in Performance Mode. It's triggered by the load of another Slot within the same Performance potentially returning to Slot 1.
It's absolutely 8.7.10, when the sound is gone INPUT LED shows no signal, also, there is no error message. I didn't try other outputs than Speaker out and didn't check the level of volume pedal, because I don't use one. I'll check it later if this problem reappears.
