Hello, I have an mpk25 that was cruising along great, then I recently plugged it in and the thing wont play certain chords.

Basically it won't play specific key combinations. Most chords are fine but it seems to be the c notes that wont play if I play another note at the same time.

Any advice where to start troubleshooting is much appreciated. I have tried 3 different usb cables so I don't think that's the issue. I suppose there could be damage to the usb port on the mpk or water spill on the key bed that I didn't notice, but I'm wondering if it could be a midi setting that I changed and forgot about.

I'm pretty new to midi and I was poking around with settings and stuff quite a bit, Sysex included. However, I don't know what I might have changed that would cause this behavior/ lack of note registration.

I reset the settings on the mpk to default to no avail.
