Rhumba and Graham,
I had a board once with sliders, and thought it was great. When I upgraded to the PSR8000, which doesn't have them I was dissapointed at first. The only problem with sliders, is you can't save them to a registration (at least not on any board I've seen). With the tools I have on the 8000, I've been able to do everything I want. It did take some time to figure it all out, but I can get the job done. I wouldn't mind if Tyros had sliders, but I wouldnt trade them for the ability to memorize a style with all my tweaks.
Later,
Midnite
