Thanks, Guitarhacker ... or can I just call you 'Hack' for short? smile

I guess the basic answer is you can't successfully use a style created in one time signature in another ... so a RealTracks style will only work in the time signature for which is was created. Since AFAIK there are no equivalent 3/4 and 4/4 RealTracks, meaning same player with same instrument and playing style.

My second thought would be that this should work well with MIDI styles where you could use F5 to change both the time signature and style at various points in the song. Then use identical instrument patches in both the 3/4 and 4/4 sections.
