I have two clips and I want them to play simulatneously, but only one to be audible at once.

I also want quickly cross fade them on a button click.

What I have tried so far is to attach them both to the main timeline on Frame 1, and have one start at volume = 100 and the other at volume = 0.

Each will individually work alone, so I know the linkage and whatnot is ok, but when both are added only one will play and their initialization codes are the same.

I have been unable to get a crossfade to work at all.

Can somebody throw me a bone on this one, I don't work with audio enough to troubleshoot this problem by myself.

Thanks.
