Be sure to add me to your favorites list New, Unused Condition Yamaha Survival Kit Software CD-ROM for both PC MAC, OLDER 2001 VERSION. This is an original Yamaha CD-ROM from a "Survival Kit" that comes with or is available for many of Yamaha's portable keyboards and digital drum pads. These include the PSR, DGX, DJX, DD and other models with a MIDI interface. It is both Windows and Mac compatible. THIS IS THE OLDER VERSION OF THIS DISK, FROM 2001. It is in new, never-used condition, in it's paper sleeve. You'll need a computer to keyboard cable to get the most out of it. If you don't have one of those, I sometimes have them in my store. Thanks for looking, and please check out my store!
