Pressing the front panel
directly: the Polysix LPF, the MS-20 LPF, and a 2-pole resonant HPF. Many more types are available by editing the on-
screen parameter. If in doing so you select one of the three types listed on the front panel, the front-panel
TYPE LEDs will update to show the selection. Selecting any other Filter Type lights the
between Types from the front-panel button, the
LPF (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.
HPF (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.
BPF (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.
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.
2-pole LPF, HPF, BPF, and Band Reject: These produce 12dB/
octave slopes for LPF and HPF, and 6dB/octave for BPF and
Band Reject. A classic synthesizer expander module used this
type of filter.
4-pole LPF, HPF, BPF, and Band Reject: These produce 24dB/
octave slopes for LFP and HPF, and 12dB/octave for BPF and
Band Reject. In comparison to 2-pole filters, these create a
sharper roll-off beyond the cutoff frequency with more
delicate resonance. Many classic analog synths used this general type of filter.
Multi Filter. This is a complex filter which is capable of all of the 2-pole filter types, and many more besides. See "Multi
Filter," on page 38.
