Hi,
An expensive way to go to convert a few styles. Can’t beleive there is no other way of doing it, most keyboards load earlier versions of a style. Have you checked with AJ if maybe there is some sort of software.
Unfortunately don’t really know anything about the newer ketrons, my last one was the
Sd1.

I do have EMC, some styles it does an ok job on, others almost not playable.
Used to do something weird to my sd1 styles, messed up expression control changes. I’d get jumps in volume on intros. May have fixed it in the meantime, this was quite a few years ago. I thought I could use EMC as a style editor, but quickly gave up on that idea.
