I can only duplicate tracks in the mixer when they are VISIBLE in the arrange window.
Don’t tell me anything about logic or reason! Because, on the other hand, it’s possible to duplicate tracks in the ARRANGE window, even when they are not visible in the mixer. But vice versa it’s not possible!
So stupid !!!
I need to change my arranger track visibility, swap to arrange window, search track, duplicate, change visibility options again, go the the mixer window again. Come on?!!?!
