I recently found a beautiful Yamaha piano with the Disklavier MX100A here in Saigon, Vietnam of all places. While everything is functioning well at the moment, I know enough that it it's just a matter of time before the disk drive goes out. I currently use the wireless MIDI interface with an app (PianoStream). I would be interested in learning more about the SSD solution/workaround. Any information you can provide would be greatly appreciated.
