I'd like what Cubase does which makes it great for orchestration -- allowing you to make graduated changes to MIDI Velocity and other parameters. Now in Studio you can highlight and raise and lower all the velocities at once the same amount, but you can't AFAIK select a half minute of track and make graduated changes to raise it up at one end of the track more than at the other, to create a gradual rise or fall of velocity or other parameter -- raising up the beginning a little, and the end a great deal all at once.
Let's be able to draw a line over the velocity track, and manipulate the ends of it up and down to adjust the velocity according, or even create points along it and make curves for dips and hills.
