I have the same issue on my BT voice. It only happens when I turn it on after it’s been sitting for a while. This sounds crazy but from what I can see it’s temperature related. My studio is pretty cold this time of year and I’ve noticed it happening more so now vs. in the summer. After about 10 minutes or so, it seems to go away.
I’ve also had strange issues with some voices when hitting the upper notes in chromatic mode. It’s almost like I get a super high resonance/decay sound even though all I have is a sample playing. Scared the crap out of me once or twice. Need to remember to check and see if that issue is also BT related.
