I'd like to be able to manipulate midi CC data via nodes with options, like jump, linear, fast curve, slow curve. This would make adjustments quite a bit easier for me and the visual easier to understand as well. I'm doing a lot of orchestral style instruments lately and being able to click a couple nodes and set to slow curve, would simplify drawing in the curve manually. And it'd make fine tuning it a bit easier, as you could just drag nodes around instead of re-drawing the curve.
