Brett plays far better than me 😮😄😁

Wersi has built in software to convert and play Yamaha styles, and by listen to the different demos, they play very well.
Wondering how much tweaking necessary to get such result as this?🤔

As far as I am aware there is no editing of the styles, it is purely just a straight conversion. (Wersi created a number of voices (Including the equivalent of the Mega voices) to give better compatibility during conversion)
The converter itself works with styles up to Genos 1, and while it should work on Genos 2 Styles, as far as I am aware new voices for the new styles were added by Yamaha, so conversion may not be as good. (Probably as usual though new voice equivalents will most likely be added in a future update)
