I remember trying to do some 'midi' stuff with the PSR6300. What a job...it wasn't helped by the fact that my computer, a Commodore 64 was in one room and the 6300 in another, with a long midi cable between them. The program we used which I don't remember now required several keypresses. The PSR needed you to press the Brass and Chimes key if I remember. My husband did the computer part in the living room and I did the 6300 button, but it only worked about one in 5 times, we never could figure out why, or what the secret was. Do you remember those little Ram cards that went with the PSR they cost a small fortune and held mostly nothing. Ah memories.
