GB won't add new track
I have a project with only two tracks. But when I go to add a new track absolutely nothing happens (either clicking on the Plus symbol or going to Track>New Track).
When I click on Track>New Track with Duplicate Settings, I get a pop-up saying, "Maximum Number of Audio Tracks. You have added the maximum number of Audio tracks (4) to your song. Delete one or more Audio tracks before adding another Audio track."
Four is the max??? No way? And the project has only TWO tracks (one vocal, and one imported audio track).
I'm on GB 10.1.0.
iMac, OS X Yosemite (10.10.4)
