I would like to add some marks (sort of annotations) at some points (more than one) of my track. Something like the arrangements marks, but on a per-track basis. I think I can't, since I can't find any information about this. But I try to ask here.. :) Thank you
You can go to TRACKS at the top and click on Show Arrangement tracks. It will add a track on top of the whole thing, then you rename it (right-click) and you treat it as a clip. I took it to the end of a clip and then marked the beginning of it and it kinda worked. I know what you mean, like while it's playing pressing M or something to mark on the spot, but I haven't found that yet!
I hope it helps!
