Resonance
Emphasizes the frequencies around
the cutoff. The control range is from 0% to
100%. With increasing values, the tonal color
changes from an open neutral sound, to a nasal
sound, to a ringing tone, caused by self-oscilla-
tion of the filter. Values above 90% usually drive
the filter into self-oscillation.
Dist
Adds color to the filtered sound by using
the integral distortion of the filter. The sonic ef-
fects range from slight overdrive of the oscilla-
tors to hard-distorted sounds with sub-harmon-
ics. The control range is from 0% to 100%.
Higher values introduce more extreme effects.
In addition, the graphic display in the middle of
the Filter section indicates the amount of satura-
tion that is used.
There are 7 Distortion modes, each with a dis-
tinct tonal character. The Dist pop-up menu
provides access to the Distortion modes.
s
Env (Envelope)
Controls the cutoff modulation
from the Filter envelope. The control range is
from 0% to 100%. Higher settings of this control
cause the filter to open wider.
Key Track Allows for cutoff modulation by MIDI
note number. The control range is from –100%
to +100%. With a low-pass filter and no key
tracking applied, higher notes sound darker as
the pitch moves beyond the cutoff. When key
tracking is set to +100% the pitch of the played
MIDI note modifies the Filter cutoff in the same
direction. Higher notes increase cutoff fre-
quency and thus avoid tonal changes over the
entire keyboard range. Settings in between re-
sult in varying degrees of tonal change.
Filter Types
The Filter section supports the following Filter
types:
LP4
Four-pole low-pass, frequencies above the
cutoff are attenuated at 24 dB/oct.
LP3
Three-pole low-pass, frequencies above the
cutoff are attenuated at 18 dB/oct.

Descriptions of the Filter Distortion Modes
Mode Description
Overdrive Creates a soft, tube-like clipping.
Distort Creates a harder, brighter clipping.
Hard Clip Creates a very hard, bright, transistor-
like clipping.
Rectify Creates a gentle distortion which
retains the character of the input.
Bit Crush Reduces the bit depth, creating delib-
erate aliasing.
Resample Reduces the sample rate, creating
deliberate aliasing
