Value Explanation
Type of filter
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.
BPF: Band Pass Filter. This leaves only the frequencies in the region of the 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
OFF, LPF, BPF,
HPF, PKG, LPF2, can use this to create wah-wah effects by employing an LFO to change the cutoff frequency
cyclically.
LPF3
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 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 RES parameter will be ignored.
0–127 Frequency at which the filter begins to have an effect on the waveform's frequency components
Emphasizes the portion of the sound in the region of the cutoff frequency, adding character to the sound.
0–127
* Excessively high settings can produce oscillation, causing the sound to distort.
Depth of the TVF envelope
-63–+63 Higher settings will cause the TVF envelope to produce greater change. Negative (-) settings
will invert the shape of the envelope.
TVF envelope times
0–127 Higher settings will lengthen the time until the next cutoff frequency level is reached.
This will modify ENV T1 (p. 54).
TVF envelope times
0–127
This will modify ENV T3 (p. 54).
TVF envelope levels
0–127
Specify how the cutoff frequency will change at each point, relative to the Cutoff Frequency
value. This will modify ENV L3 (p. 54).
TVF envelope times
0–127
This will modify ENV T4 (p. 54).
