Hi Lee,
for psr styles you don't need to record the midifiles. Just change the style's extension to .mid. Instant midifile with
MARKERS that can easily be altered to suit the Korg. Plus the psr style variations/fills are normally recorded in maj7th chords, perfect for the Korg iseries ntt setting. This way you can get away with recording only the 1 cv for each of the variations & fills.
The intro's & endings, some are done in Maj & Min versions, some are done based on maj7th chord.

When you basically play back a psr style as a midifile, when you get to the intro's & endings, on certain sections you'll hear a jumbled mess. Reason is the maj & min intro/endings are stacked on top of each other, so you hear both playing at the same time. If this happens, mute tracks 1 to 8 & you'll most likely hear the major I/E.
Mute tracks 9, 12,13,14,15, 16. You'll hear the minor version. When I convert one of these midifiles to a korg style, I basically tack any minor I/E on to the end of the midifile & delete bits accordingly.

The mp3 recordings that Diki suggested are a great idea. Really helps to know what the style is supposed to sound like.

best wishes
