Decay and Sustain pair. With these additional parameters,
you can create much more complex envelopes.
ADS1DS2R Envelope
One Shot Envelope
The One Shot envelope type is designed for percussive
sounds that don’t need a stage maintained as long as a
note is played. In other words: the envelope goes through
all its stages, no matter how long a key is pressed. This
includes even the Attack phase. It uses the parameter set
of the ADSR envelope type in which the Sustain
parameter is used to set a level breakpoint. This allows
creation of One Shot envelopes with a very percussive
attack or with a “Gate” effect. Some parameters of the
Envelope section have no function so they can not be
edited.
One Shot Envelope
Loop S1S2 Envelope
The Loop S1S2 envelope type loops the envelope
between Sustain 1 and Sustain 2 as long as a note is
held, after has been through the Attack phase once. This
means that when Sustain 2 is reached, Decay 1 is used
to reach Sustain 1 again, then Decay 2 is used to reach
Sustain 2,
and so on. As soon as the note is released, the
envelope proceeds with the Release phase. It uses the
parameter set of the ADS1DS2R envelope.
