Filter Route
This setting specifies whether the filters operate
in Series or Parallel mode. When they are in Series,
Filter 1 always passes through Filter 2. When they
are in Parallel, sources can be routed so they pass
through only one of the filters or through both
filters in varying amounts (as described in
).
The setting is linked to the parameter on Mixer
page 3, edit field 4; changing one also changes the
other.
Drive
To add extra warmth or grit to a patch, try
adjusting the Drive parameter. As the value climbs
the waveform begins to clip, and at the highest
settings the waveform can be radically distorted.
The Drive route setting determines the point at
which the overdrive is applied (see below).
When Filter 1 is selected on the top panel, the
Drive parameter is shared with the Drive / Morph
knob in the Filter Controls section.
Drive Route
There are two configurations for routing the
Drive effect: Pre or Post. The difference is whether
the waveform is boosted before it hits the filter
or whether the filter output is boosted before it
reaches the Amp stage.
• pre places the Drive effect between the
waveform and the filter.
• post places the Drive effect after the filter.
Vowel Order
This parameter is only visible when the Vowel
filter type is selected. It provides eight different
arrangements of the vocal formants, ranging from
AEIOU to UIEAO. Combined with creative use of
the Cutoff and Resonance parameters, nearly any
vowel or diphthong can be achieved.
filter 2
Filter 2 is our adaptation of a classic 2-pole state-variable filter. True to form, Filter 2 can toggle between
two filter types: Low Pass / Band Pass / High Pass, and Low Pass / Notch / High Pass. Each provides a
perfect complement to Filter 1.
The filters can be used in Series or Parallel.
This setting is found on page 3 of Filter 1.
