Terry,
I don't think the PSR-1000 has a modulation wheel.. It's set up somewhat in the way the PSR-640 differed from the PSR-740. As far as custom order on specs.. With the money you pay some things should be standard on a keyboard..... I feel modulation wheels should be included on models like the PSR-1000. I can understand having it differ with harmonizer, and other features, but something as basic as a modulation wheel. Look at budget synths. They all either have both modulation and pitchbend wheels, or a joystick that does both.
