Value Explanation
Selects the type of filter. A filter cuts or boosts a specific frequency region to change a sound's
brightness, thickness, or other qualities.
OFF: No filter is used.
LPF: Low Pass Filter. This reduces the volume of all frequencies above the Cutoff Frequency in
order to round off, or un-brighten the sound. This is the most common filter used in
synthesizers.
BPF: Band Pass Filter. This leaves only the frequencies in the region of the cutoff frequency
(Cutoff Frequency), and cuts the rest. This can be useful when creating distinctive sounds.
HPF: High Pass Filter. This cuts the frequencies in the region below the Cutoff Frequency. This is
suitable for creating percussive sounds emphasizing their higher tones.
PKG: Peaking Filter. This emphasizes the frequencies in the region of the Cutoff Frequency. You
can use this to create wah-wah effects by employing an LFO to change the cutoff
frequency cyclically.
LPF2: Low Pass Filter 2. Although frequency components above the Cutoff Frequency are cut,
the sensitivity of this filter is half that of the LPF. This makes it a comparatively warmer low
pass filter. This filter is good for use with simulated instrument sounds such as the acoustic
piano.
LPF3: Low Pass Filter 3. Although frequency components above the Cutoff Frequency are cut,
the sensitivity of this filter changes according to the Cutoff frequency. While this filter is
also good for use with simulated acoustic instrument sounds, the nuance it exhibits differs
from that of the LPF2, even with the same TVF Envelope settings.
If you set "LPF2" or "LPF3," the setting for the Resonance (p. 125).
Selects the frequency at which the filter begins to have an effect on the wave-
form's frequency components.
• With "LPF/LPF2/LPF3" selected for the Filter Type, lower cutoff
frequency settings reduce a tone's upper harmonics for a more
rounded, warmer sound. Higher settings make it sound brighter.
• If "BPF" is selected, harmonic components will change depending on
0–127
the TVF Cutoff Frequency setting. This can be useful when creating
distinctive sounds.
• With "HPF" selected, higher Cutoff Frequency settings will reduce lower
harmonics to emphasize just the brighter components of the sound.
• With "PKG" selected, the harmonics to be emphasized will vary
depending on Cutoff Frequency setting.
