#priority : Float64
#process : Bool
"Runs" the envelope
#release
Advances the envelope to the release stage.
#start(delay : Float64, attack : Float64, hold : Float64, decay : Float64, sustain : Float64, release : Float64)
Starts the envelope.
#start(region : InstrumentRegion, key : Int32, velocity : Int32)
Starts a VolumeEnvelope for an instrument.
