Decay Time
The Decay time parameter defines the length of time it takes for the level of a sustained
note to fall to the Sustain level, after the attack phase is over. If Sustain level is set to its
maximum, the Decay parameter has no effect. When the Sustain level is set to its
minimum value, Decay defines the duration or fade-out time of the note.
The Decay parameter appears as a modulation target in the Router for ENV 2 and ENV 3
individually (ENV2Dec, ENV3Dec).
Note: On pianos and plucked string instruments, high notes decay faster than low
notes. In order to simulate this effect, modulate the Decay Time target with the Kybd
source in the Router. The Router channel slider should be set to a negative value.
Sustain and Sustain Time
When the Sustain Time parameter is set to its center value—which can be achieved by
clicking the ∞ symbol—the Sustain level behaves like the Sustain parameter of any
synthesizer ADSR envelope. In this position, the Sustain level (abbreviated as S) defines
the level that is sustained for as long as the key remains depressed, following the
completion of the Attack time and Decay time phases.
The Sustain Time slider defines the time it takes for the level to rise to its maximum—or
to fall to zero—after the decay phase is over. Settings in the lower half of its range (Fall)
determine the speed at which the level decays from the Sustain level to zero. The lower
the slider position, the faster the decay speed. Settings in the upper half of its range
(Rise) determine the speed at which the level rises from the Sustain level to its
maximum value. The higher the slider position, the faster the speed of the rise.
Release Time
As with any synthesizer ADSR envelope, the Release time parameter (R) defines the time
the level takes to decay to zero after the key is released.
Vel
The Vel (Velocity Sensitivity) parameter defines the velocity sensitivity of the entire
envelope. If it is set to maximum, the envelope will only output its maximum level
when the keys are struck at maximum velocity.
