specifies the duration of the decay stage, i.e. how long
it takes to fall back to the sustain level.
Sustain
This parameter specifies the sustain level that is
reached after the decay stage ends. The sustain stage
lasts as long as a key is pressed.
Release
The final release stage is triggered whenever a key is
released. The release parameter specifies the duration
it takes the envelope to hit zero. Note that when the
sustain level is set to zero, the release parameter may
have no effect if the envelope has previously reached
zero already.
4.8 Amplitude Envelope
Located below the Filter envelope, the amplitude enve-
lope controls the progression of the volume of a sound
(see fig. 4.8). It works in the same manner as the filter
envelope.

Level
Controls the level of the amplitude envelope, which
simply boils down to the overall level of the cur-
rent voice. If you wish to modulate the volume of a
patch, this is usually the right destination parameter
to choose.
Attack
The ATTACK parameter specifies the duration it
takes for the amplitude envelope to go from zero to
its maximum level.
