I came across a webpage that tells you how to add MIDI to a Fender Rhodes piano. I think this would be really cool. I’ve heard that Chick Corea used his Rhodes Mark V with MIDI (one of 3 prototypes built at the factory) on some recordings.
But I wonder if the MIDI installation would work the same with a Rhodes Mark V as it would with an earlier Rhodes which has a wooden case. Something worth investigating.
