Filter Type
The filter will produce very different results depending on
the selected filter type. The selections will change slightly
according to the selected Filter Routing, to show the correct
cutoff slope in dB per octave.
Low Pass. This cuts out the parts of the sound which are
higher than the cutoff frequency. Low Pass is the most
common type of filter, and is used to make bright timbres
sound darker.
High Pass. This cuts out the parts of the sound which are
lower than the cutoff frequency. You can use this to make
timbres sound thinner or more buzzy.
Band Pass. This cuts out all parts of the sound, both highs
and lows, except for the region around the cutoff frequency.
Since this filter cuts out both high and low frequencies, its
effect can change dramatically depending on the cutoff
setting and the oscillator's multisample.
Filter B (High Pass)
[Low Pass, High Pass,
Band Pass, Band Reject]
PROGRAM > Filter 3–1: Filter1
With low resonance settings, you can use the Band Pass
filter to create telephone or vintage phonograph sounds.
With higher resonance settings, it can create buzzy or nasal
timbres.
Band Reject. This filter type–also called a notch filter–cuts
only the parts of the sound directly around the cutoff
frequency. Try modulating the cutoff with an LFO to create
phaser-like effects.

Bypass
This lets you bypass Filter A completely.
If Bypass is Off, Filter A functions normally.
When Bypass is On, Filter A has no effect on the input
signal.
Frequency
This controls the cutoff frequency of Filter A, in increments
of 1/10 of an octave. The specific effect of the cutoff
frequency will change depending on the selected Filter
Type, as described above.
Input Trim
This adjusts the volume level at the input to the filter. If you
notice that the sound is distorting, especially with high
Resonance settings, you can turn the level down here, or at
the Output Level.
Note: The filter will not clip internally, so there is no
difference between adjusting the Input Trim and the
Output Level. Either of these controls will allow you to
minimize clipping later in the signal chain, such as may
occur in the Drive section and in some effects.
