Control
This parameter is visible only when the Filter type
is set to Vowel. It provides control over location
and spread of the formants, which are certain
peaks and nodes in the lter frequencies that help
to approximate the resonance of the human vocal
apparatus. Use this with the Cuto, Resonance,
and Vowel Order parameters for greater precision.
Cuto
This controls the Cuto frequency for every lter
type except the Vowel lter, for which it becomes
the vowel control. When Filter 1 is selected on
the top panel, the Cuto knob also controls this
parameter.
Resonance
This adjusts the resonance of the lter. When Filter
1 is selected on the top panel, the Resonance
knob in the Filter Controls section also controls
this parameter.

Control Parameter Range Description
1 ENV 1 amount +/- 64.0 Sets amount & polarity of Env 1 eect on lter
2 LFO 1 amount +/- 64.0 Sets amount & polarity of LFO 1 eect on lter
3 Vel Env +/- 64.0 Allows velocity to set maximum range of lter envelope
4 Keytrack +/- 200% Scales lter response across keyboard; C2 = center note
ENV 1 amount
This parameter denes the amount and polarity of
the eect Envelope 1 will have on Filter 1. There is
a similar, separate parameter for Filter 2.
Envelope 1 has a pre-wired connection to the
Filter section, which saves a mod route. But a
dierent envelope can be used to control the lter
if you want; just set this value to 0 and create a
new route via The Mod Matrix (p. 61).
Keyboard model only: When Filter 1 is selected on
the top panel, the ENV 1 knob in the Filter Controls
section also controls this parameter.
LFO 1 amount
This parameter denes the amount and polar ity
of the eect LFO 1 will have on Filter 1. There’s a
similar, separate parameter for Filter 2.
LFO 1 has a pre-wired connection to the Filter
section, which saves a mod route. But a dierent
LFO can be used to control the lter if you want;
just set this value to 0 and create a new route via
The Mod Matrix (p. 61).
Keyboard model only: When Filter 1 is selected on
the top panel, the LFO 1 knob in the Filter Controls
section also controls this parameter.
Vel Env
This is an abbreviation for “Velocity to Envelope”. It
adjusts the depth of the lter envelope based on
note velocity: notes played at maximum velocity
allow Envelope 1 to have maximum impact on the
lter frequency, within the range set by the Env 1
amount parameter. It can be set negatively, so that
higher velocities reduce the range of a positive-
going lter envelope or increase the range of a
negative-going lter envelope.
There is a similar, separate parameter for
Filter 2.
Vel Env operates within the range set by
the Env 1 Amount parameter;
if you have no envelope amount set, the
parameter will do nothing.
Keytrack
This parameter scales the lter response across
the keyboard, with C2 as the center note. A
positive value means that notes above the center
note increase the lter cuto frequency, and
notes below the center note decrease the lter
cuto frequency. A negative value means that
notes above the center note decrease the lter
cuto frequency, and notes below the center
note increase the lter cuto frequency. There is a
similar, separate parameter for Filter 2.
