funny, i also stumbled over this. i remember reading about this feature but when i extended some tracks to more than one bar, no trigs were there.
but as i had my hands already there and because the sequencer buttons are so well layed out, all missing trigs were placed even before i finished asking myself wehre they are
so, currently the workflow of putting in trigs doesn’t let me miss or search the copy bar function and i didn’t even bother looking for it, sorry no help here.
one thing though is the transport section in General:
coming from Elektron Units i somehow burned “double-tap stop” into my brain and my muscle memory. and well, this just doesn’t work here but is rather pausing-unpausing the sequencer, which triggers another double-tap from my side, which… you see where this is going
and i can’t reproduce it, but sometimes i have the feeling that the cv track is a little bit off when i start the sequencer. did you encounter something similar?
but this could also come from missing concentration after 4 hours of use or so
