Explanation
(p. 74).
Adjusts the pitch in semitone steps.
Adjusts the pitch in steps of one cent.
Specifies 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 effect on partials 1 and 2.
Specifies 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 effect on partials 1 and 2.
Sets the gain (amplification) of the waveform.
The value changes in 6 dB (decibel) steps—an increase of 6 dB doubles the waveform's gain.
* This is effective if Waveform is set to 001:JP-8 Saw or a subsequent waveform.
Specifies the amount of pitch difference between the seven sawtooth waves layered within a
single oscillator.
Higher values will increase the pitch difference. (OSC Detune applies an equal amount of pitch
difference between each of the seven sawtooth waves.)
* If the Ring Switch is ON, this has no effect on partials 1 and 2.
* This is valid only if SUPER-SAW is selected for the Waveform.
Shifts the range of PW (pulse width) change. Normally, you can leave this at 127.
* If the Ring Switch is ON, this has no effect on partials 1 and 2.
Specifies the direction and depth to which the pitch will change.
Specifies the attack time of the pitch envelope.
This specifies the time from the moment you press the key until the pitch reaches its highest
(or lowest) point.
Specifies the decay time of the pitch envelope.
This specifies the time from the moment the pitch reaches its highest (or lowest) point until it
returns to the pitch of the key you pressed.
Specifies the cutoff frequency of an independent -6 dB high-pass filter.
-6 dB HPF
Selects the type and slope of the filter.

Specifies the cutoff frequency.
Resonance emphasizes the sound in the region of the filter cutoff frequency.
