If snap is set to triplets, it snaps ok to triplets but the visible gridlines do not change accordingly to triplets.
This is in 7.2.0 in Ardour 6 this worked ok.
Before reporting a bug, is there a preference or setting I overlooked?
It’s a bug and in most senses, it has already been reported.
Couldn’t find an issue in Mantis on this but if it’s known and reported than it’s ok.
