Editing the TONE Track
MIX
Here you can set the reverb, delay, pan, and level of the total eect.
Parameter Value Explanation
LEVEL
(MIX LEVEL)
0-127 Species the volume of the clip.
PAN L64-63R Species the pan of sound.
>REVERB
(Reverb Send) 0–127
Species the amount sent to TOTAL FX
REVERB.
>DELAY
(Delay Send) 0–127
Species the amount sent to TOTAL FX
DELAY.
FILTER
Here you can make lter settings.
Parameter Value Explanation
TVF TYPE
OFF, LPF, BPF, HPF,
PKG, LPF2, LPF3
Selects the type of TVF lter.
OFF: O
LPF: Low pass lter
BPF: Band pass lter
HPF: High pass lter
PKG: Peaking lter
LPF2: Low pass lter 2
LPF3: Low pass lter 3
VCF TYPE
FLAT, TYPE-JP,
TYPE-M, TYPE-P
Selects the type of VCF lter when the lter
TYPE is VCF.
Each of these simulates the operation of an
analog synthesizer’s LPF.
TYPE TVF, VCF
Select either TVF or VCF as the lter type.
* TVF stands for Time Variant Filter, and is a
lter that allows detailed settings to be made
for the time-varying change in the sound’s
frequency components.
If VCF is selected, the simultaneous
polyphony will be less than when TVF is
selected.
CUTOFF
(Cuto ) 0–1023
Selects the frequency at which the lter
begins to have an eect on the waveform's
frequency components.
RES
(Resonance) 0–1023
Boosts the region of the sound near the
cuto frequency, adding a distinctive
character to the sound.
ENV DEP
(Env Depth) -63–+63 Species the depth of the lter envelope.
KEYF -200–+200
Set this if you want the cuto frequency to
change according to the keyboard position
of the note you play.
SLOPE
-12, -18, -24 [dB/
Oct]
This button selects the slope (steepness) of
the lter.
For VCF, you can choose -12, -18, or -24.
For TVF, you can choose only -12 or -24.
If the lter TYPE is TVF, the following
limitations apply.
Only -12 dB or -24 dB can be specied.
Even if you specify -18 dB, the sound
engine operates internally with the -12 dB
setting.
If you specify -24 dB, the simultaneous
polyphony will be less than when -12 dB is
selected.
AMP
Here you can make amp envelope settings.
Parameter Value Explanation
ATTACK
(T1) 0–1023
Species the time over which the initial
value changes to the maximum value after
the key is pressed.
DECAY
(T3) 0–1023
Species the time over which the SUSTAIN
value is reached following the ATTACK.
SUSTAIN
(L3) 0–1023
Species the sustain value of the amp
envelope.
RELEASE
(T4) 0–1023
Species the time over which the minimum
value is reached after the key is released.
PAN PTL1–4
(Pan) L64–63R Species the pan of each partial’s sound.
EQ
Here you can make equalizer settings.
Parameter Value Explanation
SW OFF, ON Turns the equalizer on/o.
LOW -24–+24 [dB] Gain of the low frequency range.
MID -24–+24 [dB] Gain of the mid frequency range.
HIGH -24–+24 [dB] Gain of the high frequency range.
MIDQ 0.5–16.0
Bandwidth of the mid frequency range.
Set a higher value for Q to narrow the
range to be aected.
LOW 20–16000 [Hz] Frequency of the low range.
MID 20–16000 [Hz] Frequency of the mid range.
HIGH 20–16000 [Hz] Frequency of the high range.
EFFECT
Here you can make eect settings.
Parameter Value Explanation
SWITCH OFF, ON Turns the eect on/o.
TYPE
Refer to the MFX/
IFX parameters.
Switches the type of eect.
Eect parameters
The displayed parameters depend on the
eect type that is selected.
Detailed Sound Editing
How a Tone Is Constructed
A tone consists of four (Partial 1–4) sets of OSC, Filter, AMP, LFO × 2, and
EQ settings, together with multi-eect (MFX) settings.
You can create sounds by combining the four partials.
Each partial can be turned on/o, allowing you to select which partials
produce sound.
Partial 4
Partial 3
Partial 2

MFX
OSC (oscillator)
This selects the waveform that is the basis of the sound, and
species how its pitch will change.
Filter
This modies the frequency components of the sound.
Amp (amplier)
This creates changes in volume and pan.
