One more observation for me and the other person with a P800II: apparently it is possible via MIDI to push the sequencer parms. (they're global, remember) out of legal range... whenever you load patchbanks from someone else, go right to para. mode and look up parms. 85 and 86 , clock and repeat. If there is a letter or high number, or it can be heiroglyphics, hold the DOWN button until the display scrolls to a 1 or 2; if you don't the results are highly unpredictable up to and including crashing the machine.mn
