Trigger and four Re-Trigger parameters become available. These parameters are used
to configure the triggering (and re-triggering) of the envelope.
In the following seven examples, we illustrate the interaction among the trigger

function contains a fourth parameter,

The envelope is started by an On level from the selected modulation
source.
During the Modulation Source On, the envelope proceeds normally
through Delay, Attack, Decay1, and Decay2 stages to the Sustain
stage.
1. If the Modulation Source On signal continues until the Sustain
stage is reached, the Modulation Source On or SUSTAIN PEDAL
ON will HOLD at the SUSTAIN Level until Modulation Input

proceed to RELEASE1 and continue through to the end of the
envelope.
2. If Modulation Input OFF occurs before the SUSTAIN Stage is
reached, SUSTAIN PEDAL ON will "jump" and HOLD the
envelope in the Sustain Stage at the Current Level until SUSTAIN
PEDAL OFF, afterwards, the envelope will proceed to RELEASE1
and continue through to the end.

will proceed to RELEASE1 Stage and progress normally through
the envelope to the end.
2. If a Modulation Input OFF (assuming Sustain Pedal is OFF) event
occurs before the envelope reaches the SUSTAIN stage, the
envelope will "jump" immediately to the RELEASE1 stage time
(at current level) and proceed to the Release2 Level within the
time of the Release1 Stage. When the RELEASE2 stage is reached
the envelope will proceed normally through to the end.
