TR Lowpass 4p

A four-pole lowpass filter, with 24 dB attenua-
tion per octave above the cutoff frequency.

TR Lowpass 5p

A five-pole lowpass filter, with 30 dB attenuation
per octave above the cutoff frequency.

Acid Lowpass

This special filter mimics a four-pole transistor
network with unbuffered filter stages. The result
is a rather dark timbre, unlike any of the other
filter types.

Sallen-Key

The Sallen-Key filters are two-pole, multi-mode filter
designs. What makes them special is the sound of the
resonance, which is very different from all other filter
models. The resonance is highly distorted, yielding a
very aggressive sound.

SK Lowpass 2p

A two-pole lowpass filter, with 12 dB attenuation
per octave above the cutoff frequency.

SK Bandpass 2p

A two-pole bandpass filter, with 6 dB attenua-
tion per octave on either side around the cutoff
frequency.

SK Highpass 2p

A two-pole highpass filter, with 12 dB attenua-
tion per octave below the cutoff frequency.

Dune

Dune 2 incorporates two filter types from Dune 1
("Lowpass 12dB" and "Lowpass 24dB"), to facilitate
creating patches that sound similar to Dune 1 patches.

Dune 2p

A two-pole low-pass filter, with 12 dB attenua-
tion per octave above the cutoff frequency.

Dune 4p

A four-pole low-pass filter, with 24 dB attenua-
tion per octave below the cutoff frequency.

4.7.3 Filter Effect

Dune 2 features a filter effect section, which allows to
perform additional processing in series with the main
filter. The filter effect can be processed before or after
the filter. Click-and-drag either the filter or the ef-
fect box to change the order of processing. The order
