Thanks for your advice. The PX-3 would be fine if not for the fact that it doesn't do user-set microtones, 'scale tuning.' It has the usual bundle of tunings and temperaments found in the other newer Privias but they're pre-set and lack some of the better keyboard temperaments, particularly the Young temperament which sounds just lovely on the piano. If the WK-7500's piano voices are the same as the Privia PX-330 it might be just the ticket for bringing the beauty of well temperaments into the otherwise bland equal-tempered keyboard scene as that keyboard happens to have scale tuning capability. The reason I jumped on the PX-330 when it first came out is because it was not only affordable and got good reviews but offered different tunings and temperaments, even though the only two historical Western unequal temperaments in the bundle are too rough and extreme to be as useful as other, smoother, unequal temperaments out there--even so, they're so interesting and colorful to play around with once in a while, to remind the ears what pure intervals, tone color and harmony in keyboard music can really be like. It's like going on a vacation and coming back to the same-old same-old with a fresh perspective. I call the PX-330 on its wooden stand and three pedals my "Piano Piano" since it emulates an acoustic piano experience so well. I play mostly in equal temperament to preserve the piano illusion. It would be good to have another decent keyboard that doesn't so much pretend to be a piano, just a contemporary sonic engine with its own sound and touch, capable of being just as expressive as a piano. Now to keep justifying all that and jump on the WK-7500 when I have some of that mythical disposable income... Bill
