Filter Controls
You can choose from 55 different filter types or choose “No Filter”, which bypasses the
filter section.
Most of the filters have two parameters: Frequency (or Morph) and Resonance (Q,
Gain, Body Size). These two parameters can be continuously varied during the note
(choose realtime resonance).
The frequency response curve of the filter is accurately shown in the display as you
change the initial filter settings. Frequency is shown on the horizontal axis, with
amplitude on the vertical axis.
High values of Q or resonance amplify frequencies near the cutoff or center frequency.
In a swept EQ filter, gain controls the amount of boost or cut. In a phaser or flanger,
resonance determines the depth of the effect. In the vocal filters, body size determines
the apparent size of the mouth cavity.
You will notice an increase in voice count when the filters are bypassed as the filters
steal cycles from your computer’s CPU. 12th order filters use more CPU and therefore
decrease the maximum voice count.
Filter Descriptions
Filter Name Order Type Description
2-pole Lowpass 02 LPF Typical OB type low-pass filter with a shallow
12 dB/octave slope.
4-pole Lowpass 04 LPF 4-pole low-pass filter, the standard filter on
classic analog synths. 24 dB/octave rolloff.
6-pole Lowpass 06 LPF 6-pole low-pass filter which has a steeper
slope than a 4-pole low-pass filter. 36 dB/
octave rolloff!
2-pole Highpass 02 HPF 2-pole high-pass filter. 12 dB/octave slope.
