Effect Block
• R (Release Time)
Value: 0–100
The elapsed time from when Trigger In is switched
"Off" until the cutoff frequency return to the original
(pre-attack) value.
• These are the filter envelope settings. Select the contour
through the attack, decay, sustain, and release, and set the
degree of effect with the envelope depth. If a negative
value is selected for the envelope depth, the envelope
shape is inverted.

Velo Sens (Velocity Sens)
Value: 0–100
Sets the degree to which the cutoff frequency reflects the
value of the Velocity in Common. As the value is
increased, the cutoff frequency which follows the Velocity
(the strength or force at pressing key) gets higher.
Cutoff KF (Cutoff Key Follow)
Value: Off, On
This setting determines whether the cutoff frequency
changes according with the Note Number in Common
(On) or not (Off).
Ext Lev Follow (External Level Follow)
Value: -100–100
Sets the degree to which the linked external input
volume level changes the cutoff frequency. As the value
is increased, you get an effect in which the tone changes
more dynamically according to the rhythm of the input.

VCA (Virtual VCA)
This reproduces, virtually, the VCA (Voltage Controlled
Amplifier).
Sounds from the VCF are amplified as they change over
time, and the resulting amplified volume levels and changes
are then output.
Initial Gain
Value: 0–100
Sets the reference volume. When set to any value
except 0, sound plays even when the Trigger In is turned
Off, with the volume increasing as the value is increased.
(Volume changes based on the envelope, LFO, or other
input are added to this volume level.) Thus, when setting
Trigger In for regulation of sound expression, set this to
0, and regulate the volume with the envelope depth.
Envelope
• Depth
Value: 0–200
Sets the depth of the envelope (the function of
changing the amplifier's volume over time).
• A (Attack Time)
Value: 0–100
The elapsed time from when Trigger In is switched
"On" to the point of maximum volume.
• D (Decay Time)
Value: 0–100
The elapsed time from the point of maximum volume
until reaching the sustain level (next item).
• S (Sustain Level)
Value: 0–100
The volume level after passage of the decay time
(previous item) up until Trigger In is switched "Off."
• R (Release Time)
Value: 0–100
The elapsed time from when Trigger In is switched
"Off" until the volume reaches its minimum value.
• These are the volume envelope settings. Select the
contour with attack, decay, sustain, and release, and set
the degree of effect with the envelope depth.
