Hi Eddie & Machetero,
the KN styles on the Korg site, not sure if they'd be KN7's, I think they're from the earlier models.

KN styles just got more & more sophisticated thru the models.

The earlier KN2,3, & 5 may convert more easily than the KN7.

Unfortunately the fact that you tweaked the styles, I don't think would come thru in a conversion.

One reason I do mine from midifiles rather than thru EMC ( whenever possible) EMC removes multiple tempo changes in intro's & endings. It doesn't always get the drums quite right, few other quirky things here & there.
Mind you , I wouldn't be without EMC, I've been upgrading it for the last 20 years or so.

It's just that the korg Import/Export of styles as midifiles is good on the korg, I prefer to do mine that way.
