Hello
I have a Casio Tone Bank CT-650 from I think 1989. I got it passed down from a relative back a while ago and everything worked fine on it then, but now pretty much everything does not work. The only thing that works is the default piano sound when you turn it on. The Tone Bank control doesn't work, the rhythm stuff doesn't work, none of it. I would greatly appreciate some help as it has some very unique sounds that I just love. Thanks!
Edit: Now when I switch the Chord/MIDI switch, it will change the sound from the default piano to different ones. Very strange.
