The megavoices are intended to give this keyboard instrument an "acoustic" edge, that is to add the sparkle of a life performance by emulating the fundamental acoustic and rhythm instruments, the guitar and bass. The Sweet! voices give solo's the edge in realism, the Live! voices add presence and dynamics (e.g. the Live! Drum kits and strings, pianos and Brass) whilst the Cool! voices add warmth and character, e.g. the Jazz guitars and electric piano.
Certainly performing live with the megavoices is probably out of the question, and I dont think that was Yamaha's intention. They are added for creating authentic backing tracks, styles and accompaniment and with the right programming and playing techniques, they give the user more creativity and potential. No matter how good a player you are, its frustrating to be held back by cheesy sounds. On the contrary, if you cant play very well, dont expect to get the best out of these new sounds.
I agree that 10 megavoices doesnt sound much, but then a guitarist doesnt own 10 guitars and a bass player doesnt usually have several basses to play. No doubt in the future we will see more of these "megavoices" appearing in new models, I expect yamaha will begin to introduce them into their psr range with time for enhancing the styles. remember the tyros has a whopping 96MB of voice wave memory, thats more than any other keyboard I know of. Most of that is consumed by these voices, so they do require considerable resources.
As always, the demos are slick and will show off what can be done with the right skills.. as to achieving the same yourself, only time will tell! But it will be fun trying!!!!
