General music's Genesys is a joy for navigation and with 1024 user presets make them a real joy. It has sliders for instant adjustments for volume Etc. The Pro weighs a lot less so is much more portable. These instruments are worth taking a very hard look at.
I cant' say how Genesys compares with the Rolands that Fran speaks of but I would bet he would be pleasantly surpised. I've had the Yamaha Psr 2000 and the Technics KN 7000 and I feel the Genesys blows them away in General ease of use. The sounds and styles are subjective and this post was about use in a live performance.
