- The
Bi
polar or
Uni
polar selector allows you to set the polarity of the selected modulation.

The Output connections:
- [ Audio ]: This is the audio output of the filter. It can be connected to another filter (for a
serial filter connection) or directly to a VCA input.
9.1.1.2.5 Origin filter
This filter is a special “low CPU cost” Origin filter. This module offers very good sound
characteristics for a low CPU charge. You can use it for a very “big” preset including lots of audio
modules.
The Origin filter
- The [ Frequency ] knob sets the cut-off frequency of the filter
- The [ Resonance ] knob sets the amplification amount of frequencies close to the cut-off
frequency. The other frequencies are either unchanged (below the cut-off frequency) or
reduced (above the cut-off frequency). When you increase the resonance, the cutoff
frequency is more and more amplified. At very high resonance values, the filter starts to
self oscillate, giving a sort of “whistle” sound.

The types:
The [Type] selection box selects the filter type. It offers a wide variety of filter types:
- [ 4P LP ] or [ 2P LP ] select a low pass filter. In this mode the filter progressively attenuates
frequencies above the cut-off frequency. [4P LP] selects a 4-pole (24dB/Oct) slope, [2P
LP] selects a 2-pole (12dB/Oct) slope.
- [ 4P HP ], [ 2P HP ] or [ 1P HP ] select a high pass filter. This filter acts as the inverse of a
low pass filter. It progressively attenuates frequencies below the cut-off frequency.
[
4P HP ] selects a 4-pole (24dB/Oct) slope, [ 2P HP ] selects a 2-pole (12dB/Oct) slope and
[ 1P HP ] selects a 1-pole (6dB/Oct) slope
- [ 2P BP ] or [ 4P BP ] select a band pass filter. A band pass filter is a combination of a high
pass and low pass filter, attenuating frequencies above and below the cutoff frequency.
You can for example use it to make a sound more “pinched”. [2P BP] selects a 2-pole
(12db/Oct) slope, [
4P BP ] selects a 4-pole (24dB/Oct) slope.
- The [ Notch ] filter is the opposite of the band pass filter. It eliminates the frequencies
inside a band of frequencies. The resonance allows you to accentuate the sag of a band of
frequencies.

The Input connections:
- [ Audio ]: This is the audio input of the filter. You can connect it to the output of an
oscillator or a mixer if you use several oscillators (or other audio modules).
