Filter Mode
With the buttons on the left of the Filter subpage you determine the overall filter
structure. The filter types Classic and Tube Drive provide the following options:
Filter Shape
Each filter type offers 24 different filter shapes. By selecting the filter shape you
determine which frequencies will be affected. The letters and numbers indicate the
filter shape: For example, LP12 is short for low-pass 12dB/oct. Depending on the
chosen filter mode, you can either select one, two or four shapes.
Filter mode Description
Single Filter This mode uses one filter with one selectable filter shape. You can
select any of the 24 filter shapes.
Dual Filter Se rial This mode uses two separate filters connected in series. You can
select any of the 24 filter shapes for each filter independently. The
parameters Cutoff and Resonance control both filters
simultaneously. However, you can offset the cutoff and resonance
of the second filter with the parameters CF Offset and Res Offset.
Dual Filter Parallel This mode uses two separate filters connected in parallel. You can
select any of the 24 filter shapes for each filter independently. The
parameters Cutoff and Resonance control both filters
simultaneously. However, you can offset the cutoff and resonance
of the second filter with the parameters CF Offset and Res Offset.
Morph 2 This mode morphs between filter shape A and B. You can select
any of the 24 filter shapes for filter shape A and B independently.
Adjust the morphing with the Morph Y parameter.
Morph 4 This mode morphs sequentially from filter shape A to D. You can
select any of the 24 filter shapes for filter shape A, B, C and D
independently. Adjust the morphing with the Morph Y parameter.
Morph XY This mode morphs freely between the filter shapes A, B, C and D. In
other words, the morphing can be any mix between the four filter
shapes. You can select any of the 24 filter shapes for filter shape A,
B, C and D independently. Adjust the morphing with the Morph X
and Morph Y parameters.
Filter shape Description
LP24 Low-pass filter with 24 dB/oct. Frequencies above the Cutoff will be
attenuated.
LP18 Low-pass filter with 18 dB/oct. Frequencies above the Cutoff will be
attenuated.
LP12 Low-pass filter with 12 dB/oct. Frequencies above the Cutoff will be
attenuated.
LP6 Low-pass filter with 6 dB/oct. Frequencies above the Cutoff will be
attenuated.
BP12 Band-pass filter with 12 dB/oct. Frequencies below and above the
Cutoff will be attenuated.
BP24 Band-pass filter with 24 dB/oct. Frequencies below and above the
Cutoff will be attenuated.
HP6+LP18 High-pass filter with 6 dB/oct. plus low-pass filter with 18 dB/oct.
(asymmetric band-pass filter). Frequencies below and above the
Cutoff will be attenuated. Attenuation is more pronounced for the
frequencies above the Cutoff.
