Hi,if the problem persists you can still delete the system exclusive message, if available. Start looking at the start of track 1 event list for the sysex message. If you don't find it try track 2 and so on. Remember, if there's such a message you'll have to delete it because if you don't, any patch change you try to insert won't work: the sysex message, if it includes a patch change midi message, will prevail.
