Value Description
OFF The filter will not be used.
Low Pass Filter.
LPF
The region above the cutoff frequency will be cut, making the sound more mellow.
Band Pass Filter.
BPF The region around the cutoff frequency will remain, and the regions above and below
will be cut. This is a useful way to create a distinctive sound.
High Pass Filter.
HPF The region below the cutoff frequency will be cut. This is appropriate for percussive
sounds with a distinctive high-frequency component.
Peaking Filter.
PKG The region around the cutoff frequency will be emphasized. You can produce a wah
effect by using an LFO to cyclically change the cutoff frequency.
Low Pass Filter 2.
The region above the cutoff frequency will be cut, but the filter sensitivity will be half
LPF2
that of LPF. This is suitable for simulating instruments such as acoustic piano.
* If "LPF2" is selected, the RESONANCE setting will be unavailable .
Low Pass Filter 3.
The region above the cutoff frequency will be cut, but the filter sensitivity will change
according to the cutoff frequency. This is suitable for simulating acoustic instruments,
LPF3
but even with the same TVF ENVELOPE settings, it will produce a sound with a
different nuance than LPF2.
* If "LPF3" is selected, the RESONANCE setting will be unavailable .
TONE The setting most appropriate for the tone will be used.
-50–+50 Specifies the frequency at which the filter will begin to be applied.
Boosts the region near the cutoff frequency, giving the sound a distinctive character.
-50–+50
Raising this value excessively may cause oscillation and distortion.
Specifies the amount by which your playing strength will vary the cutoff frequency.
-50–+50
With positive "+" values, stronger playing will raise the cutoff frequency.
-50–+50 Specifies how nuances of your performance (p. 28) will affect the filter cutoff frequency.
Specifies the curve by which your playing strength will affect the cutoff frequency.
Normally, you should choose "TONE. " The optimal curve for each tone will be used.
If you don't want the cutoff frequency to be affected, choose "FIX. "
FIX,
1–7,
TONE
1
Specifies how the pitch of the note you play will affect the cutoff frequency.
-200–+200
With positive "+" values, the cutoff frequency will rise as you player higher notes.
Adjusts the depth of the TVF envelope.
-50–+50
Higher values will increase the change produced by the TVF envelope.
-50–+50 Adjusts the attack time of the filter envelope.
-50–+50 Adjusts the decay time of the filter envelope.
-50–+50 Adjusts the sustain level of the filter envelope.
-50–+50 Adjusts the release time of the filter envelope.
Specifies how your playing strength will affect the filter attack time.
-50–+50
With positive "+" values, stronger playing will shorten the attack time.
-50–+50 Specifies how nuances of your performance (p. 28) will affect the filter attack time.
