Someone mentioned this to me about drums and I think I might have given out wrong information assuming the drums or the drum set names were not available at the time.
Now I've come across it with a plugin.
In the tracks window the track number, name, output, pgm number and plugin name are italic'ed and the track is muted.
The track name in the graphic editor is italic'ed as well.
Has the track gone offline?
Only way to bring it to life was delete it.......which is really replacing it with another.......but I don't know how I got in the position to start with.
