By default, when Global Time is set to 100%, the duration indicated by another parameter is the
value applied. But, if for example, the attack says 2 seconds, a GT setting of 50% will make the
attack being actually 1 second long.
At mid-fader setting, the GT is 100%. Going down tends towards 0%, going up, to 800%. Therefore,
the longest duration for each envelope stage is 30 seconds x 8 = 4 minutes.
When activating the editing on multiple envelopes and changing the GT, the percentage applied
will be the same, but each envelope resulting timings will be different if their initial values were
not the same.
It might be convenient to set GT according to the kind of envelopes you intend doing. For
example, when doing percussions not exceeding a few seconds, setting the GT at 20% will restrict
the longest stage duration to 6 seconds. This will give you the best control of that maximum
duration over the entire fader length for attack, decay, etc.
Note: When Global Time is at 0%, any envelope is reduced to a pulse !
Output Level
This sets the voltage span of the envelope signal. At maximum, the envelope goes up to 8 Volts.
Note that CV control of this setting offers a virtual VCA on each envelope.
Curve shape
The Attack, Decay and Release can each be shaped individually from logarithmic to exponential
curves via linear when set halfway. The typical analog ‘exponential decay’ curve is obtained with
the setting at around 70%.
Trigger Mode
Envelopes are usually controlled with a gate: their duration is related to the duration of the
incoming gate signal.
Gate
Without hold being active, the end of gate is the start of the release phase; this may occur at any
time, even during the Attack, Punch or Decay phase.
Trigger
When triggered, the whole envelope duration is defined by the addition of each phase: pre-delay,
attack, punch, decay and release. The envelope develops automatically through these phases till
the end.
Without hold (long enough), the release immediately follows the decay. This creates an ADSR
envelope where the sustain level is reached but its duration is zero.
When hold is long enough to go beyond the end of the decay phase, a sustain phase is created.
