I received the PianoDisc diskette by mail. Indeed, it does play on my PR902 in 'direct Play' mode. I ordered a jazz disk, which has a number of good tune on it. I use these disks to jam along with on my Yamaha WX-5 Wind Controller. The disks are rather expensive and they sound as if they have been poorly quantitized - perhaps they were sequenced with a resolution of 1/32 note or less - some of the passages sound kludgy.
