Vortex Sound Research

My Rev2 is a bit glitchy...among other things like having a single key play a totally different patch is a stuck sequence when I switch to Basic Program. If I go into the sequencing menu, it doesn't report that there is anything there, but it will auto-play a short sequence every time I initialize the patch as soon as it receives MIDI clock start. Any ideas how to clear this permanently? I don't want anything playing unless I set it up myself. Oh, and doing a factory reset doesn't seem to work either (pressing "Write" doesn't do anything). Thanks.
