Hmm… I don’t use song mode very much, so this wasn’t something that I’d considered before now but it’s probably the expected behavior. I agree that if there’s no workaround it’s pretty limiting, musically.
Submit a feature request is the best suggestion that I have right now, maybe someone else has a proper workaround though.
I’m assuming that it doesn’t matter what length of trig you’ve set or if there’s nothing else on the track?
