The EG parameters allow you to shape the sound of a Part’s Voice — or,
in other words, set how the level and timbre of the Voice changes over
time. This section also includes independent Pitch Envelope Generator
(PEG) parameters for controlling how the pitch of a Part’s Voice changes
over time.
The relationship of the main EG parameters — Attack, Decay and Re-
lease — are shown in the illustration below. These parameters not only
affect the sound level, but also the timbre (with the Filter parameters; see
page 111).

2) Long Attack, Decay, Release times:
Even though the key is held for the same length of time in both examples,
the sound of the second example slowly reaches full volume and decays
over a longer time. It also sustains longer after the key is released.
Keep in mind that the EG parameters affect each other, and are affected
by how long a note is held. For example, if Decay is set to a low value
and the note is held for a long time, you may not be able to hear changes
made to the Release parameter.
