I don't know how to play piano, but have a DGX-500 and YPG-635 keyboards. I would like to try and learn "A WHITER SHADE OF PALE" by Procol Harem. I was wondering if anyone can tell me how to make one of these keyboards sound like the organ sound in that song. Also wondering where I might get style files and stuff without going through the Yamaha website. I really want to learn, but am 70 and on fixed income. Any ideas would be GREATLY appreciated.
