Rikki:

There is no track off sysex that I am aware of, but you can trick the PSR into playing the track without sounding. Just change the MSB Bank Select for the tracks (you will need to look in the CASM to see which midi tracks go to the Bass , etc) to a value that the PSR does not use, say 100. Your other midi devices probably don't use the XG specification and will ignore the MSB, but the PSR will consider it illegal and not play anything.The program CasmEdit is an easy way to look up the Casm and edit the MSB events.

Regards,

Michael
