Explanation
No filter is used .
Low Pass Filter . This reduces the volume of all frequencies above the cutoff frequency (Cutoff Freq)
in order to round off, or un-brighten the sound .
This is the most common filter used in synthesizers .
Band Pass Filter . This leaves only the frequencies in the region of the cutoff frequency (Cutoff Freq),
and cuts the rest . This can be useful when creating distinctive sounds .
High Pass Filter . This cuts the frequencies in the region below the cutoff frequency (Cutoff Freq) .
This is suitable for creating percussive sounds emphasizing their higher tones .
Peaking Filter . This emphasizes the frequencies in the region of the cutoff frequency (Cutoff Freq) .
You can use this to create wah-wah effects by employing an LFO to change the cutoff frequency
cyclically .
Low Pass Filter 2 . Although frequency components above the Cutoff frequency (Cutoff Freq) 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 .
* If you set "LPF2," the setting for the Resonance parameter will be ignored (p . 51) .
Low Pass Filter 3 . Although frequency components above the Cutoff frequency (Cutoff Freq) 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 .
* "LPF3,"
If you set the setting for the Resonance parameter will be ignored (p . 51) .
Selects the frequency at which the filter begins to have an effect on the waveform's frequency
components .
"LPF/LPF2/LPF3"
With selected for the Filter Type parameter, 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 the TVF Cutoff Frequency
setting . This can be useful when creating distinctive sounds .
"HPF"
With selected, higher Cutoff Frequency settings will reduce lower harmonics to emphasize
just the brighter components of the sound .
"PKG"
With selected, the harmonics to be emphasized will vary depending on Cutoff Frequency
setting .
*
You can control this parameter using the Matrix Control .
MEMO
To edit the overall tone while preserving the relative differences in the Cutoff Frequency values
set for each partial, set the Cutoff Offset parameter (p . 43) .
Emphasizes the portion of the sound in the region of the cutoff frequency, adding character to the
sound . Excessively high settings can produce oscillation, causing the sound to distort .
