You could probably get close enough with a Tyros 4/S-950, KORG, Audya, Etc units.. to many of the sounds heard in this video...just sayin' whats all the fuss?
But you could never get the real time comtroll over the sounds, thats what you get with all thos knobs on the fromt side.
For me more brands should make that format of stage piano.... They are perfect underground for your arranger, A setup like this makes 3 keyboard setups possible again... And 2 keyboard setups verry accesible, espescially to all those former organ players enjoying more keybeds/manuals
