If the Roland is something like the EP-760 (or many other pianos they made 30 years ago) it can probably also be a controller, FWIW.
I have one still (well my daughter has it currently), a very serviceable keyboard.
Just a thought.
What model Roland is it?
If it has a working keyboard and MIDI out, it's a controller at the very least. <grin>
