Gray Market Upgrade
2012-04-30 by lpressley3
I have a circa 1991 gray market Disklavier. The only way to play music on it is through DD floppy disk. It also has a MIDI in and out. I've heard that, despite what everyone believes, this are upgradable. Does anyone know this to be true (or false). Any information would be greatly appreciated.
Thank you,
Crawford
