Page 6: VDF EG
Here you can specify the shape of the VDF EG (enve-
lope generator) that will determine how the VDF cut-
off frequency will change over time.
In “Page 5: VDF”, the EG Intensity parameter allows
you to adjust the depth of the effect produced by the
oscillator EG. Also, the “Page 7: VDF keyboard track-
ing”, parameter settings allow the EG to be automati-
cally adjusted according to the keyboard position or
key velocity.
Switch between oscillators 1 and 2 by pressing the
VARIATION buttons [1] or [2].
AT (Attack time)
[00…99]
This sets the time over which the cutoff frequency will
change from the normal VDF setting to the Attack
Level (A).
With a setting of 0 the movement will take place
instantly, and with a setting of 99 the movement will
be the slowest.
A (Attack level)
[–99…+99]
Sets the level at which the cutoff frequency will arrive
after the Attack Time has elapsed.
With positive (+) settings the Attack Level will be
higher than the normal cutoff frequency, and with
negative
(–) settings it will be lower.
DT (Decay time)
[00…99]
Sets the time over which the VDF cutoff frequency will
change from the Attack Level (A) to the Break Point
(B).
Set it in the same way as the Attack Time parameter.
B (Break point)
[–99…+99]
Sets the level at which the VDF cutoff frequency will
arrive after the Decay Time (DT) has elapsed.
Set it in the same way as the Attack Level parameter.
ST (Slope time)
[00…99]
Sets the time over which the VDF cutoff frequency will
change from the Break Point (B) to the Sustain Level
(S).
Set it in the same way as the Attack Start Time parame-
ter.
S (Sustain level)
[–99…+99]
Sets the level at which the VDF cutoff frequency will
arrive after the Slope Time (ST) has elapsed.
Set it in the same way as the Attack Level parameter.
RT (Release time)
[00…99]
Sets the time over which the VDF cutoff frequency will
change from the Sustain Level (S) to the normal cutoff
frequency after you release the key.
Set it in the same way as the Attack Time parameter.
