Hi,
the addition of some sort of a universal style & sound format that would allow any keyboard to load the same basic set of bread n' butter styles Factory & User. Still have it's own fancier mega sound styles or audio loop styles in it's native format.
Just means that when changing keyboards these styles will play back perfectly whether it be on yamaha, ketron, whatever.

Bit like what GM did for the song file.

best wishes
Rikki
