When creating an arrangement with RealBand..
When to Regenerate?
1 - If you change tempo?
2 - If you change the chords?
3 - If you change Part Markers?
4 - After you change the song length?
5 - Or when?

I find myself doing it after every change... is that the way to do it?

Also, does Regenerating change the tune? It seemed to earlier today when I was experimenting with an arrangement and changed the tune length by adding a bar.

Thanks for any help.
