it depends, what is the source : Genos, Tyros 5 or earlier ?
Korg can´t handle neither "RevoDrums" nor "AudioDrums", and, as already mentioned, no MEGA and SA Voices.
Of yourse you can change the sty extension to .mid, but then you should first remove all MEGA-Voices ( mega-voice remover from jorgen sorensen ) and split the midi-part from the part that includes the control-parameters ( use "CASM-Edit" for it. )
It would be very easy if Yamaha could export it´s styles as MIDI, like Korg can do it.
I´m quite sure that it takes less time to programm the desired style completely new ( or changing an already existing Korg-style ) than trying to convert it.
BTW: Its ( at least in germany, but I think in the whole world ) NOT ALLOWED to use Yamaha styles in keboards of other brands ( Copyright )
