Hi Lee,
some of the Yammie users create their styles from standard song midifiles,, but they don't quite end up with what you're suggesting.
For starters, you'd have to compomise on the number of tracks, you've only got the 8, so would depend on how heavily it was orchestrated, you'd possibly have to leave some out.
Secondly with the software used ( OMB , EMC (song to style), or Jorgens Midi2Style, the chord progressions for Variatons & Fills are automatically transposed to a single maj7th chord to suit Yamaha styles. Might mess up a melody based phrase, can't remember if there's a way around it, haven't done it for a while.
To create a normal type of style (with a song specific intro /ending), the song based midifile would have to be treated the same way as a midifile for a yammie ie any chord progressions in variations & fill parts, the notes would have to be transposed to a single chord. (any of the above software could probably be used, I'm most familiar with OMB).
Another thought & this may be whacky, (I've also never tried it, )
could be to maybe to just chop the midifile into suitable sections, Intro, verse , chorus, fills, set them to No Transpose & just trigger them as required. You couldn't actually change chords, you'd just play melody. Probably not all that different to playing over the top of a midifile, except that the the tune could be extended in realtime. As I said, I've never tried it, so purely hypothetical if it will work.
best wishes

My description of a song specific style is ...let's say I want to play Andrew LLoyde 'Webbers's 'All I Ask Of You'. I would like a style to be able to do into...variations etc and ending that fit the song exactly...especially with all the counter melody and instrument accomapyments.
I would be very happy if that could be done without having to actually come up with all the music...in other words from a standard MIDI file of the song. I am a better technician than musician.

Sounds hard??
