Just found this site. This is my first post.
I am trying to recall my Roland XP50 back to life. Actually is works okay....except for the selector knob/wheel. This makes my experience most frustrating when trying to use the keyboard. I had it looked at by Sweetwater Sound and they said the price to repair would be more than it was worth.
I was thinking for trying to sell to Guitar Center (they don't want it) or on Ebay and just trade out for something lesser, but with functioning buttons/wheels. But in a recent conversation I had the idea of using a synth module or rack synth, whatever you call them plugged into the ?midi out on the keyboard.
Would this work? Using just the RolandXP50 for the keys itself, and the module to do the selecting/controlling the voice?
