Hi, I have a Yamaha MU15 Tone Generator with an in-built keyboard (absolutely tiny!). It also has MIDI In + Out and says "General MIDI" and something about "XG". I really want to use it to control the keyboard on Synthedit. I just cannot for the life of me figure out how to do it, or more importantly, if it can be done at all. I tried using MIDI IN controller but that did not work. Any help you may have will be greatly appreciated.
