musicmanht.., cost isn't really the issue in terms of putting the touch screen into an arranger. Proof that cost isn't as serious of a factor is the new Korg M50. This synth/workstation has a touch screen and the unit is selling for less than the PSR-S900.., and about $100 more than the PSR-S700.

I know the M50 isn't an arranger, but if Korg can put something like this in a synth/workstation and keep the price just barely over $1,000 then the issue of cost really isn't a factor.

I don't think Yamaha has any intention of adding a touch screen to any of their arrangers.., and if they did you'd bet (based on Yamaha pricing) they'd majorly jack the price to the consumer.

Also it wasn't until the release of the Motif XS that yamaha finally got into check and added that nice color screen. Korg's been using the touch screen since the Trinity.., and carried it over to their arrangers. Roland's using it on the G-70 and the new V-Synth GT has a killer touch disply.. Roland was also using a color screen on the Fantom X when Yamaha's Motif ES still used the old mean green.

I don't see Yamaha adding touch screens to arrangers anytime soon.., and IF they did you'd find it on a Tyros replacement (which will probably translate to an additional $200-$400) to the consumer.
