I have a Casio PX-800 digital piano attached to an audio interface with midi ins and outs.

Quite often, when I use the PX-800 as a midi input in Sonar and I try to record a performance using the PX-800, I get an error message in Sonar that it has to shut down. I would think that it is the audio interface (a Focusrite Saffire LE), but I had the same problem with a cheap midi usb cable.

What midi message or other message could my digital piano be sending Sonar that would be causing it to shut down? I don't know what to do to be able to record my piano performance.
