For some reason, the draw tool does not work when trying to draw in the boxes in the articulation lanes with the expression map. I can click in some lanes and they will fill in but not in others and not consistently. I have tried different expression maps and different VSTs (Cinesamples, East West Play) and all the same result.
When you insert Directions their lengths last until the next Direction
Attributes are attached to notes, so they are one-offs, you might say.
