Hi Bachus,
Just checked the video.

Just out of interest how did you go with the major and minor, intro/endings?

I do mine in a similar fashion, but I do mine on an the old xg works sequencer.

Change all the markers, the bass and percussion channels, fix up the intro / endings, then import it into korg as a single midi file 0.
Then I edit volumes , sounds etc in the korg.

I thought you meant he was using the song to style conversion tool, but must admit I found video a bit hard to follow.
