All this goes back to a rumor on psr tutorial forums...

I dont see why yamaha cant have 2 different style engines in the instrument... depending on what style you choose it chooses the engine... the only problems i see for the old styles are :

The controll surface of the new styles is incompatible with the old interface... this could be solved by moving part of the "old" style comtrolls to the touchscreen, and using the new interface for the new styles where aplicable..

Yamaha might want to remove some of the very old (like 15 years) for. The instrument, as they are low quallity and not wanted in a new instrument anymore... Yamaha could solve this by adding a mapping that maps old sounds in the style engine to new sounds of the genos... will not be optimal, but with some edditing styles could be high quallity again..


So... while i am hoping for a new and revolutionairy artificial intellignet style engine... i hope they dont throw away the old engine nad compatibillity... there is just to much good(y)ness in the current style database..

However, i also realise that if the jump forward is big enough people will accept this... but if the jump is less then stellar... people will revolt...
