can someone explain to me what tool to use to get a sustained note to cresendo or decresendo?
I'm not sure you can apply a dynamic variance to a single note successfully (I hope I'm wrong).
You should be able to achieve a change by insterting a multipoint controller volume command. Try experimenting with that - it's on the Insert menu.
