This example shows the functionality of an A(S)R envelope. As always, the Attack
stage rises to maximum, and proceeds to the next available Decay stage. In this case,
since D1TIME and D2TIME are set to 0, the “next available Decay stage” does not
exist, and the envelope proceeds to the Sustain stage.
As the Sustain stage is encountered, maximum level is held if a key is being held
down or a sustain pedal is depressed. When the key or pedal is let go, the envelope
proceeds from its current level (maximum, in this case) to Release2. Because Release2
is our exit stage and always decays to zero (plus Offset, if any), this functions exactly
as an A(S)R envelope.
With this same method, a simple Attack/HOLD envelope could be created by setting
the Release2 Time to HOLD (maximum).
