Hi Jos,
I do realize a style recorded as a midifile can be converted ( I've been fiddling round, doing it for years,) the problem is, it needs someone with a access to a kn7 in the first,and someone with the knowledge & patience to do it. It takes ages and that's one of the reasond why you haven't seen kn7 styles converted.
Even then, just say, you recorded the midifile based on the chord of cmaj, the 5 accompaniment style parts ( kn7)can may contain notes other other than what you'd expect to find in a c chord ie a's d's b's. The kn7 can handle these notes.
On a BIAB midifile if you record the midifile based on the cmaj chord , I'm fairly certain you only find c's e's g's ( correct me if I'm wrong).

Psr styles are based on CMaj7 chords. Therefor the notes you find in the 2 chord & the pad part are ususually cegb. It also has the 2 phrase parts which I think can handle notes other than ( cegb) That being the case I don't think a psr could probably handle a kn7 style (because of those additional notes )I doubt it would play the styles back correctly. I doubt my Va7 could either.

best wishes
Rikki

About not being able to convert the KN7 to PSR, you're definetely wrong. Any style that can be recorded in a MIDI file can be converted. I used this method with BIAB styles and the styles from a Roland E-66. It
