Editing the Tones (TONE)
Group Parameter Value Description
FILTER
FILTER TYPE
OFF The lter will not be used.
LPF
Low Pass Filter.
The region above the cuto frequency will be cut, making the sound more mellow.
BPF
Band Pass Filter.
The region around the cuto frequency will remain, and the regions above and below
will be cut. This is a useful way to create a distinctive sound.
HPF
High Pass Filter.
The region below the cuto frequency will be cut. This is appropriate for percussive
sounds with a distinctive high-frequency component.
PKG
Peaking Filter.
The region around the cuto frequency will be emphasized. You can produce a wah
eect by using an LFO to cyclically change the cuto frequency.
LPF2
Low Pass Filter 2.
The region above the cuto frequency will be cut, but the lter sensitivity will be half
that of LPF. This is suitable for simulating instruments such as acoustic piano.
* If “LPF2” is selected, the RESONANCE setting will be unavailable.
LPF3
Low Pass Filter 3.
The region above the cuto frequency will be cut, but the lter sensitivity will change
according to the cuto frequency. This is suitable for simulating acoustic instruments,
but even with the same TVF ENVELOPE settings, it will produce a sound with a
dierent nuance than LPF2.
* If “LPF3” is selected, the RESONANCE setting will be unavailable.
TONE The setting most appropriate for the tone will be used.
CUTOFF # -50–+50 Species the frequency at which the lter will begin to be applied.
RESONANCE -50–+50
Boosts the region near the cuto frequency, giving the sound a distinctive character.
Raising this value excessively may cause oscillation and distortion.
CUTOFF VELOCITY SENS -50–+50
Species the amount by which your playing strength will vary the cuto frequency.
With positive “+” values, stronger playing will raise the cuto frequency.
CUTOFF NUANCE SENS -50–+50 Species how nuances of your performance (p.28) will aect the lter cuto frequency.
CUTOFF VELOCITY CURVE
FIX,
1–7,
TONE
Species the curve by which your playing strength will aect the cuto frequency.
Normally, you should choose “TONE.” The optimal curve for each tone will be used.
If you don’t want the cuto frequency to be aected, choose “FIX.”
1 2 3 4 5 6 7
CUTOFF KEYFOLLOW -200–+200
Species how the pitch of the note you play will aect the cuto frequency.
With positive “+” values, the cuto frequency will rise as you player higher notes.
TVF
TVF ENV DEPTH -50–+50
Adjusts the depth of the TVF envelope.
Higher values will increase the change produced by the TVF envelope.
TVF ATTACK TIME -50–+50 Adjusts the attack time of the lter envelope.
TVF DECAY TIME -50–+50 Adjusts the decay time of the lter envelope.
TVF SUSTAIN LEVEL -50–+50 Adjusts the sustain level of the lter envelope.
TVF RELEASE TIME -50–+50 Adjusts the release time of the lter envelope.
TVF ATTACK VEL SENS -50–+50
Species how your playing strength will aect the lter attack time.
With positive “+” values, stronger playing will shorten the attack time.
TVF ATK NUANCE SENS -50–+50 Species how nuances of your performance (p.28) will aect the lter attack time.
