It will probably be our luck in that Yamaha will probably sell some extra piece of gear to purchase in order to modify, or make all the old styles compatible with the newest arranger. Or, make us purchase some kind of computer program to do the same.
That all depends on the new technollogy... And since Yamaha makes more money from their online store then from you reissuing old styles... it could just as well not happen at all.. Keep in mind that Yamaha is syill creating Tyros with homeplayers in mind, and in general they care less for backward compatibillity then gigging players..
Just saying, but there indeed have been a few rumors of the Genos not being compatible with the Tyros range styles at all...
Offcourse, if YAmaha was willing to invest... there could be 2 style players (just like there is an audio and a midi player) being totally independent of eachother... and the system using the player rquired by the file type..
It can go both ways, how important is backward compatibillity for you when buying a new arranger?
