HPF (High-Pass Filter)
This type of  lter cuts the frequency range that is below
the cuto frequency, emphasizing the high-frequency
range.
This can be used to create percussion instrument sounds
with a distinctive high-frequency range.

BPF (Band Pass Filter)
This type of  lter passes only the range of frequencies
in the region of the cuto frequency, cutting the other
frequencies.
This is suitable for creating distinctive sounds.
If you’ve selected “NOISE” as the oscillator waveform,
selecting this  lter type will allow only a speci c frequency
region of the noise to be heard, allowing you to play
“pitched noise.”

PKG (Peaking Filter)
This type of  lter boosts the range of frequencies in the
region of the cuto frequency.
By using the LFO to cyclically modulate the cuto
frequency, you can use this to produce a wah e ect.

BYPASS
The sound will not be sent through the  lter. The oscilla-
tor’s sound will be output without change.
[ MODE] button
This button selects the type of  lter that will be applied to
the waveform.
Press the button to make the indicator light for the desired
type of  lter.
Pressing the button cycles you through the available
choices, as follows: LPF HPF BPF PKG BYPASS
LPF ...
[ SLOPE] button
This button selects the slope (steepness) of the  lter.
Press the button to toggle the indicator between unlit and
lit. This allows you to switch between slopes of -12 dB and
-24 dB per octave.
Example: LPF (Low-Pass Filter) slope

-12 dB-24 dB
Unlit (-12 dB)
The  lter slope will be gentle; some sound near the cuto
frequency will remain.
Lit (-24 dB)
The  lter slope will be steep; the sound immediately above
(or below) the cuto frequency will be cut.
[ CUTOFF] knob
This knob speci es the  lter cuto frequency.
LPF
Turning the knob toward the right will brighten the sound;
turning it toward the left will make the sound darker (more
mellow).
HPF
Turning the knob toward the right will make the sound
lighter (thinner); turning it toward the left will make the
sound heavier (thicker).
BPF
Turning the knob toward the right allows the high-
frequency range to be heard; turning it toward the left
allows the low-frequency range to be heard.
PKG
Turning the knob toward the right will move the boosted
region toward the high-frequency range; turning it
toward the left will move the boosted region toward the
low-frequency range.
* If “BYPASS” is selected as the  lter mode, turning the
[CUTOFF] knob will not a ect the sound.
