DECAY
The DECAY knob determines the amount of time required for the control signal
to fall from the maximum level achieved by the Attack stage to the Sustain
level as the key is held. The DECAY knob has a range from 2 milliseconds to 10
seconds. Fast decay times are useful for creating articulated lead notes, while
longer decay times allow a note to fade slowly into the Sustain level.
SUSTAIN
While the Attack, Decay, and Release parameters deal with time, the Sustain
parameter controls level. Once the Attack and Decay stages are complete,
the control signal will remain at the level set by the SUSTAIN slider, keeping
the Amplitude and/or Filter at a steady level for as long as a key is held.
RELEASE
The RELEASE knob determines the amount of time required for the control
signal to fall from its current level to zero once a key is released. The RELEASE
knob has a range from 2 milliseconds to 10 seconds. Shorter settings are good
for classic funk basses that end abruptly, while longer settings are good for
creating smooth musical tails that ring out over time.
