whoa that was strange. I finally found the midi port under settings , there is a choice of A and C. It was set to C, so I change it to A. I didn't work, but suddenly after 5 minutes it started to work! I did not see this setting in the manual. Also, you can change registrations one after the other, but to change a tone, it seems like you must wait 15 seconds from whatever previous event you sent. Anyway Thank you!!!!!
