You're not going to play J. Lewis style on a keyboard are you??? If so you better use weighted keys. His style of playing will destroy a synth action keybed. A Yamah PSR-3000 woudn't last 48 hours under his fingers The Roland G-70, and Tyros 2 keybed might have a fighting chance, but even that's pushing it!
