sour notes - RESOLVED

[Jim]

Most of my VIs default to a PB value of 2 semi-tones. So, a value of 2048 would be pretty noticeable. Even though this issue has been solved using science, we still can't rule out I'm losing my mind.

I second the potatoes.

I highly recommend downloading MIDI Monitor for this kind of troubleshooting in the future, you would have seen the erratic pitch right away and where it is coming from etc.

Thanks for this link. I've installed it and am able to see my controller misbehaving in real time.

Until I can fix or replace the keyboard, I've opted to disable Pitch Bend in the Setup > Input Filter, and can enable it when I plan on using PB.

I did a web search, and apparently, this is a fairly common issue with many brands of MIDI keyboard controllers.

Removing the pot & cleaning it can be pretty painless (depending on the keyboard). Won't always fix it, but sometimes it does. You could also try just exercising it a bunch to see if it clears the dust or whatever.
