About the Filter Types
You select which filter type to use using the buttons around the filter cutoff knob. The
following filter types are available (listed clockwise from 9 o’clock):
Master Volume and Pan
The master Volume controls the master volume (amplitude) of the instrument. By
default this parameter is controlled by Envelope 1, to generate an amplitude envelope
for the oscillators.
The Pan knob controls the position in the stereo spectrum for the instrument. You can
use Pan as a modulation destination.
Shift Internally, each filter consists of two or more subfilters connected in
series. This parameter shifts the cutoff frequency of the subfilters. The
result depends on the selected filter type: For low-pass and high-
pass filter types it changes the filter slope. For band-pass and notch
filter types it changes the bandwidth. The Shift parameter has no
effect if either the 12
dB LP or 12 dB HP filter type is selected.
Tracking If this parameter is set to values over the 12 o’clock position, the filter
cutoff frequency increases the further up on the keyboard you play.
Negative values invert this relationship.
If the Tracking parameter is set fully clockwise, the cutoff frequency
tracks the keyboard by a semitone per key.
Type Description
12 dB LP Low-pass filters let low frequencies pass and cut out the high
frequencies. This low-pass filter has a gentler slope (12
dB/Octave
above the cutoff frequency), leaving more of the harmonics in the
filtered sound.
18 dB LP This low-pass filter also has a cascade design, attenuating
frequencies above the cutoff frequency with a 18
dB/Octave slope,
as used in the classic TB 303 synth.
24 dB LP This filter type attenuates frequencies above the cutoff frequency with
a 24
dB/Octave slope, which produces a warm and fat sound.
24 dB LP II This low-pass filter has a cascade design which attenuates
frequencies above the cutoff frequency with a 24
dB/Octave slope,
which produces a warm and dark sound.
12 dB Band This band-pass filter cuts both high and low frequencies above and
below the cutoff frequency with a 12
dB/Octave slope, producing a
nasal and thin sound.
12 dB Notch This notch filter cuts off frequencies near the cutoff frequency by
12
dB/Octave, letting the frequencies below and above through. This
produces a phaser-like sound.
12 dB HP A high-pass filter is the opposite of a low-pass filter, cutting out the
lower frequencies and letting the high frequencies pass. This high-
pass filter has a 12
dB/Octave slope, giving a bright and thin sound.
24 dB HP This filter has a 24 dB/Octave slope, giving a bright and sharp sound.
