PCM Synth Tone (PCMS)

Parameter Value Explanation
TVF tab
Filter Type
Selects the type of lter.
A lter cuts or boosts a specic frequency region to change a sound’s brightness, thickness, or other qualities.
OFF No lter is used.
LPF
Low Pass Filter. This reduces the volume of all frequencies above the cuto frequency (Cuto Freq)
in order to round o, or un-brighten the sound.
This is the most common lter used in synthesizers.
BPF
Band Pass Filter. This leaves only the frequencies in the region of the cuto frequency (Cuto Freq),
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 cuto frequency (Cuto Freq).
This is suitable for creating percussive sounds emphasizing their higher tones.
PKG
Peaking Filter. This emphasizes the frequencies in the region of the cuto frequency (Cuto Freq).
You can use this to create wah-wah eects by employing an LFO to change the cuto frequency
cyclically.
LPF2
Low Pass Filter 2. Although frequency components above the Cuto frequency (Cuto Freq) are
cut, the sensitivity of this lter is half that of the LPF.
This makes it a comparatively warmer low pass lter.
This lter 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).
LPF3
Low Pass Filter 3. Although frequency components above the Cuto frequency (Cuto Freq) are
cut, the sensitivity of this lter changes according to the Cuto frequency. While this lter is also
good for use with simulated acoustic instrument sounds, the nuance it exhibits diers from that of
the LPF2, even with the same TVF Envelope settings.
* If you set “LPF3,” the setting for the Resonance parameter will be ignored (p. 51).
Cuto Frequency
0–127
Selects the frequency at which the lter begins to have an eect on the waveform’s frequency
components.
With “LPF/LPF2/LPF3” selected for the Filter Type parameter, lower cuto 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 Cuto Frequency
setting. This can be useful when creating distinctive sounds.
With “HPF” selected, higher Cuto 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 Cuto Frequency
setting.
* You can control this parameter using the Matrix Control.
MEMO
To edit the overall tone while preserving the relative dierences in the Cuto Frequency values
set for each partial, set the Cuto Oset parameter (p. 43).
Resonance
0–127
Emphasizes the portion of the sound in the region of the cuto frequency, adding character to the
sound. Excessively high settings can produce oscillation, causing the sound to distort.
* You can control this parameter using the Matrix Control.
