I'm an owner of an older disklavier with a DKC5R control unit. The floppy drive was finally starting to fail on my piano so I decided to see what I could do to keep my piano workable since the latest control units from Yamaha aren't fully compatible with my piano. I bought a raspberry pi (Raspberry Pi - Wikipedia, the free encyclopedia) a USB midi controller and created a web-browser interface to allow me to upload and play midi files on my disklavier from a tablet or PC. I've moved my whole library onto the raspberry pi and now using my disklavier is more convenient than before. I'm sort of proud of what I was able to do and I'm wondering if anyone else needs a similar solution. If there's enough interest I can put together a small batch of the properly programmed mini computers. I'm not looking to do this to make money, but I'm not going to do this for free either. ; Let me know if you have the same problem. If there's enough interest I'll post some more details and put something together for distribution. If no one else needs this, I'll just continue enjoying controlling my disklavier from my tablet.
Regards,
J
