I had been working on soldering the wires to the Schober 61 note keyboards, but was not happy with the wire management. I had been keeping my eye out for controllers and found an Edirol PC-50 keyboard controller for $10 on Craigslist. Only $10? It had a bad key which I fixed with a pencil eraser. Planning to work more on the software, foot pedals and expression pedals and save the bulk of the soldering work for later.
