EG (Envelope Generator) Controls
The envelope generator controls affect the level "enve-
lope" of the sound — i.e. its attack, decay, and release times.
Plotted against time, the level envelope looks something like this.
Attack
A (Attack Time)
Adjusts the attack portion of the envelope generator curve
from "-64" through "0" to "+63". Negative values pro-
duce a faster attack while positive values produce a slower
attack. The graphic envelope generator curve will shift to
indicate the current setting (the heavy default setting curve
will also remain on the display).
D (Decay Time)
Adjusts the decay portion of the envelope generator curve
from "-64" through "0" to "+63". Negative values pro-
duce a faster decay while positive values produce a slower
decay. The graphic envelope generator curve will shift to
indicate the current setting (the heavy default setting curve
will also remain on the display).
R (Release Time)
Adjusts the release portion of the envelope generator
curve from "-64" through "0" to "+63". Negative values
produce a faster release while positive values produce a
slower release. The graphic envelope generator curve will
shift to indicate the current setting (the heavy default
setting curve will also remain on the display).
