Oy ve. So last show I had a MIDI reverse polarity event with the new cable, and then I had this situation where in the middle of my performance, I wound up at the first registration in the file folder and with the style associated with registration button #1 playing. I had registration freeze on. What the hell is going on? I'm thinking that this must be the keyboard. I wasn't even sure that I pressed the footpedal.
What MIDI or Sysex event could do this?
I had bought another MIDI Solutions device, but it's defective.

As I have two SX900 keyboards, I think I'm going to switch.
