The buttons in the piano roll for velocity, length, and h/v movement should not require being held down. If I’m using my pencil to edit, it would be much more fluid to select notes, tap horizontal movement (or whatever), move the notes and the tap again to unlatch. I am typically holding iPad with one hand and doing editing etc. with the other. Holding something down to engage that function is pretty awkward in that scenario especially because I am left-handed. This is one of the main issues I have found with CB3 in my few weeks of using it. Everything else has been great! Thanks
