Explanation
OSC
(Oscillator)
(Waveform) Refer to “Digital OSC Waveform List” (p. 74).
Pitch
(OSC Pitch)
-24–0–+24 Adjusts the pitch in semitone steps.
Detune
(OSC Detune)
-50–0–+50 Adjusts the pitch in steps of one cent.
PWM Depth
(Pulse Width
Modulation Depth)
0–127
Species the amount (depth) of LFO applied to PW (Pulse Width).
If the Waveform has selected
V
(PW-SQR), you can use this slider to specify the amount of LFO
modulation applied to PW (pulse width).
* If the Ring Switch is on, this has no eect on partials 1 and 2.
PW
(Pulse Width)
0–127
Species the pulse width.
If the OSC Wave has selected
V
(PW-SQR), you can use this slider to specify the width of the upper
portion of the square wave (the pulse width).
Decreasing the value will decrease the width, approaching a square wave (pulse width = 50%).
Increasing the value will increase the width, producing a distinctive sound.
* If the Ring Switch is ON, this has no eect on partials 1 and 2.
PCM Gain -6, 0, +6, +12
Sets the gain (amplication) of the waveform.
The value changes in 6 dB (decibel) steps—an increase of 6 dB doubles the waveform’s gain.
* This is eective if Waveform is set to 001:JP-8 Saw or a subsequent waveform.
S-Saw Detune
(Super Saw Detune)
0–127
Species the amount of pitch dierence between the seven sawtooth waves layered within a
single oscillator.
Higher values will increase the pitch dierence. (OSC Detune applies an equal amount of pitch
dierence between each of the seven sawtooth waves.)
* If the Ring Switch is ON, this has no eect on partials 1 and 2.
* This is valid only if SUPER-SAW is selected for the Waveform.
PW Shift 0–127
Shifts the range of PW (pulse width) change. Normally, you can leave this at 127.
* If the Ring Switch is ON, this has no eect on partials 1 and 2.
PITCH ENV
(Pitch Envelope)
Depth
(Pitch Envelope Depth)
-63–0–+63 Species the direction and depth to which the pitch will change.
Attack
(Pitch Envelope Attack Time)
0–127
Species the attack time of the pitch envelope.
This species the time from the moment you press the key until the pitch reaches its highest
(or lowest) point.
Decay
(Pitch Envelope Decay Time)
0–127
Species the decay time of the pitch envelope.
This species the time from the moment the pitch reaches its highest (or lowest) point until it
returns to the pitch of the key you pressed.
FILTER
(Filter)
HPF Cuto 0–127
Species the cuto frequency of an independent -6 dB high-pass lter.

Cuto
(Filter Cuto)
