Graham,
I am unable to duplicate your problem, but I think I know why.
Your registrations have songs stored in them, and when we try your registration, we don't have the song, so we're not able to duplicate your settings.
From my review of your registrations, there are several things I think you should check:
1. R1 in both registrations has an intro stored. But in your video, after you pressed R1, there was no intro -- only the style. After you press R1, you should be hearing the intro. The style variation itself should start after the intro.
2. Your registrations have songs stored in them. In both regs, you have I:/4 SONGS/Trilogy.MID, and in Edelwiess, you have in addition this song: C:/SONG/Multitrack Recordings/ClimbEveryMountain.WAV. I think what you're hearing when you initially load the registration, and press a chord, the the song playing (ie, it's drowning out the style).
3. Your registration sequence in Edelweiss is 2,3,4,5,6,7,8. Why doesn't it start with 1, if that's where your intro is?
Hope his helps,
Fred
