Again, may be the newness of the program and I'm lacking in knowhow, but bounce in place does not seem to work for a region on a summing track stack. True? It's greyed out when I try it here.

You cannot bounce into place track stacks, which sucks but I think the programmers missed that part in the development. In the producing Hip Hop tutorial they explained that you can't bounce into place track stacks.

Thanks for the info. Bummer. Hope that gets fixed in an update.
