I have several songs with a backing track, click track and queue track I created, and I need to replace the backing track with one that doesn't have a count in click in the track (don't want to count in sent to P.A. mains). So far I can't figure out a way to add another track to an existing song. Creating a new song will be a huge hassle as I have many flags for patch changes and midi commands that I would have to do all over again (hours of work). Is there any way to add a file to an existing song in Showcase?
