(Pitch Envelope Level 0–4)
-63–+63
Specify the pitch envelope levels (Level 0–Level 4). It determines how much
the pitch changes from the reference pitch (the value set with Coarse Tune
or Fine Tune on the Pitch screen) at each point. Positive (+) settings will cause
the pitch to be higher than the standard pitch, and negative (-) settings will
cause it to be lower.

Value Explanation
Filter Type
Selects the type of filter. A filter cuts or boosts a specific frequency region to change a sound’s bright-
ness, 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. 103).
Cutoff Frequency
★
0–127
Selects the frequency at which the filter begins to have an effect on the waveform’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 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.
To edit the overall patch while preserving the relative differences in the Cutoff
Frequency values set for each tone, set the Cutoff Offset (p. 90).
★
You can use matrix control to modify this. (p. 95)
