Filter Envelope (Page 2)
Delay (00 to 99)
This is the amount of time that the envelope will wait before
doing anything; very useful if you want to affect one element of
a sound sometime after the sound starts. When the Delay is set
to 0, the envelope attacks right away, without any delay. Play
some notes while turning up the delay and see that the time
between playing the note and hearing the effect of the Filter
Envelope gets progressively longer as the Delay control is turned
up.
If the Delay is set above 99, the display will read "Hold". This
indicates that the Delay stage of the envelope will wait
indefinitely until the key is released before continuing on to the
remaining envelope stages (Attack, Decay, etc.). This requires
that the Filter Envelope's Trigger parameter (see next page) is set
to "Freerun". However, when the Delay is set to "Hold",
"Freerun" mode is forced on regardless of the Trigger
parameter's setting.
Sustain Decay (00 to 99)
This is the amount of time that the envelope will take during the
sustain stage to bring the level down to 0. If this is set to 99, the
envelope will remain at the Sustain level until the note is
released. This is the normal setting for organ-type sounds. When
set to 0, the envelope's level will immediately jump down to 0
upon reaching the sustain stage.
Trigger (Normal, Freerun, Reset, Reset-Freerun)
The Trigger mode determines how the envelope will function.
You may select either Freerun or Reset, or both (Reset-Freerun)
or neither (Normal). When set to Normal, the envelope will
always start at its current level (i.e., if another note had been
played which triggered the envelope's cycle, playing another
note in the middle would not interrupt the cycle). Also in
Normal mode, the envelope will immediately advance to its
release stage upon releasing the note. When set to Freerun, the
envelope will complete its entire cycle, even if the note is
released in the middle. When set to Reset, the envelope starts at
the beginning whenever a new note is played. When set to Reset-
Freerun, the envelope will start at the beginning whenever a
new note is played and will complete its entire cycle, even if the
note is released in the middle.
If a sound layer's Keyboard Mode parameter (found in the Pitch
Function, Page 3, Quad Knob [4]) is set to "Mono", the Filter
Envelope will only retrigger when playing legato if the Trigger
Mode is set to either "Reset" or "Reset-Freerun".
