Hello everyone,

I'm facing an unusual issue with my MPC1000. Certain buttons on the device are not responding as they should. For instance, when I press F1 on the main screen, instead of functioning as the expected button, it triggers the OPEN WINDOW function. Similarly, when I press F2, it acts as the overdub button, and so on.

Has anyone encountered a similar problem? I attempted to resolve it by replacing the official operating system with the free version of JJOS, but the error persists. Could this indicate a defect on the circuit board?

Any help is greatly appreciated.

My 2500 started doing that a few months ago. Maybe the PCB board is corrupted? Now I'm using the 1k. Both have JJOS 2xl.

Anybody got some suggestions?
