Main Window
Common
Level Adjusts the overall volume of the JX-3P.
Adjusts the brightness (tonal character) of the
Brilliance
sound.
Chorus Turns the chorus on/off.

LFO
Here you can create cyclic change (modulation) in the sound.
Rate
Determines the speed of the LFO.
Specifies whether the LFO cycle starts at the
Key Trig moment you press the key (ON) or is not
synchronized with the key-press (OFF).
(p. 6)
If this is ON, the envelope starts repeatedly at
Trig ENV
intervals of the LFO cycle.
MODULATION
Here you can use LFO and ENV-1 to modulate the DCO and VCF.
LFO Mod
(DCO-1/DCO-2)
VCF
ENV Mod
(DCO-1/DCO-2)
VCF
This is a low-pass filter that passes the low frequencies and cuts the
high frequencies.
Cutoff
Resonance
4
Turns on/off the pitch modulation applied by the
LFO to the DCO.
Adjusts the depth by which ENV-1 controls the
VCF cutoff frequency.
Turns on/off the pitch modulation applied by
ENV-1 to the DCO.
Specifies the cutoff frequency of the low-pass
filter. Frequency components above the cutoff
frequency are cut.
Resonance boosts the sound in the region of the
filter's cutoff frequency.
Higher settings produce stronger emphasis,
creating a distinctively "synthesizer-like" sound.
