EG (Envelope Generator) —————————————————
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 100).
1) Short Attack, Decay, Release times:
Level

Decay
Max.
Min.
Key is pressed
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.
