Attach a modifier to the volume level parameter. Assign a controller to it-- Exp pedal for manual, or ADSR for auto. the trick to ADSR controlled swells is to set the attack fairly slow, like a few hundred milliseconds, run the level up to 100%, and then set sustain and release to taste.
Then play with the modifier curve and ADSR attack to fine tune the swell.
