THANKS A LOT TO MARKUS AND JOHN PITCAIRN for great advice. Both the 'megasong' and multiple apps in OS X are great solutions. I have a question for John about multiple copies of Logic: how does Logic Control deal with this situation? As far as megasong, I've tried this before, but I still have a problem importing the environments. The 'update environment' routine eludes me: I always end up with multiple copies of the same objects, probably due to different ID numbers being assigned to objects that to my EYES look the same. It's a fair bit of work importing tempo maps and changing meters too. If it's all 4/4 with default environments I'd say the megasong idea is the way to go. Unfortunately for me, I'm dealing with a fair bit of complex stuff THAT I MUST SIMPLIFY! Logic lets you go wild, but then the cleanup can be a pain... I will likely try a combination of megasong and multiple renamed copies of Logic. Thanks guys! John Oliver
