Currently when you input note data in the Editor on an Instrument Track by double click when the Arrow selected or with the Pencil tool, you can drag the mouse up or down to set the desired velocity of the newly drawn note instantly.
That's great. However there's no acoustic feedback when doing that (mind the C3 note in the example below, it's not re-triggering on velocity change).
No acoustic feedback (subsequent volume change on input)
So I would like to suggest a feature where the user receives acoustic feedback when the mouse is dragged up or down subsequently after a new note is drawn. Just like how it behaves when holding CTRL+ALT on an existing note to adjust its velocity (mind the C3 key, it is re-triggering on velocity change to give acoustic feedback).
