I'm using Win XP Pro. I get a message on the page title bar saying that it is generating and I watch the numbers for each track go up in percentage, starting from 0 to 100%. It seems that it generates each Real Track separately. 12 seconds??? Wow... I would LOVE it if that's all it took. I read in my user manual that I should be using Replay but when I make a change it still does the same thing. It seems that Replay only works when there's no changes made. I'll try your tip about the Combo part.

Thanks
Bobby
