● 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.
A (Attack Time)
Adjusts the attack portion of the envelope generator curve
from “-64” through “0” to “+63”. Negative values produce 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 produce 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).
