I heard a new rumor all older Yamaha styles will NOT be compatible with the new alleged so called Genos because of newer technology used..?
The other way is understandable and reasonable, new styleformat will not load into models before "Genos",
but I doubt Yamaha will put the new flagship on the market without make compability for load i.e Tyros and PSR styles.
If what you heard is correct, I think they aim for other usergroup than "TYROSERS".
How many Tyros / PSR users do you think will go for a swap if so?
Yamaha want to sell big numbers, so my guess is that there will be software to convert.
Onboard or as PC addon.
