So just wanted to share this in case it happens to you too:
Tried to run Overbridge for the first time in a while. Got some weird error how the OS isn’t correct. Ignored it, pressed play on my RYTM which then froze my DAW and RYTM machine (nothing was responding). I then rebooted. Immediately after, RYTM would make a continuous buzzing sound. Like a stuck analog note. I trouble shooted and by process of elimination realized its only from the CH/OH engine (if either pad was un-muted the buzzing sound would come back and not stop unless I rebooted and muted those pads before pressing play again).
However, I did a re-calibration from the System menu and it seemed to have solved it (for now). Hoping my RYTM is ok and it was some weird Overbridge fluke. Anybody else have something similar happen?
