OSC SYNTH
Pitch data and attack data are extracted from the bass sound
that is input, and the signal produced by the internal
oscillator will be output.
* This cannot be switched on/off.
PRESET
Select one of the preset OSC synth types.
SHAPE SQ=0, SW=100–SQ=100, SW=0
Specifies the type of internal oscillator signal that will be output.
LEVEL 0–100
Adjusts the volume of the synth sound.
SENS (Sensitivity) 0–100
Specifies the waveform by adjusting the balance of SQ
(square wave) and SW (sawtooth wave).
PWM WDTH (PWM Width) 0–100
Adjusts the width of the positive phase and negative phase
of the SQUARE wave.
PWM RATE 0–100
Adjusts the frequency at which the pulse width of the
SQUARE wave will be modulated.
PWM DPTH (PWM Depth) 0–100
Adjusts the depth to which the pulse width of the SQUARE
wave will be modulated.
* PWM WIDTH, RATE, and DEPTH will have no effect if
SHAPE is SW=100 and SQ=0.
ENV FLLW (Envelope Follow) OFF, ON
When set to “ON,” the sound is generated according to the
amplitude of the strings.
When set to “OFF”, the sound is generated at the certain
level.
HOLD OFF, ON
This function sustains the output of the synth sound. If you
turn Hold “On” while the synth sound is being output, the
output of the synth sound will be held until you turn it “Off.”
It would be useful when you assign it to the CTL pedal, and use it
while you perform (p. 23). Normally, you should set this “Off.”
CUTOFF (Cutoff Frequency) 0–100
Adjusts the brightness (hardness) of the sound. Increasing
this value will brighten the sound.
RESO (Resonance) 0–100
Adjusts the amount of resonance (tonal character) for the
synthesizer sound. Increasing this value will produce a more
strongly distinctive tone.
F.TYPE (Filter Type) -12 dB, -24 dB
Specifies the depth of the effect produced by the filter.
F.ATTACK (Filter Attack) 0–100
Specifies the attack time of the filter.
F.DECAY (Filter Decay) 0–100
Adjusts the time over which the filter will come to rest.
F.DEPTH (Filter Depth) -50–+50
Adjusts the depth of the filter. Increasing this value will
produce a greater amount of filter change. “+” and “-” will
cause the filter to move in opposite directions.
SUB OSC OFF, DETUNE, -1OCT
Adds depth to the sound by layering a synth sound onto
each string.
DETUNE -50–+50
Specify the pitch of the DETUNE sound in units of a cent.
LEVEL 0–100
Specify the volume of the DETUNE sound or -1OCT sound.
FILTER
The sound is routed through a filter to adjust the brightness
and tonal character.
* This cannot be switched on/off.
PRESET
Select one of the preset types of filter.
CUTOFF (Cutoff Frequency) 0–100
Adjusts the brightness (hardness) of the sound. Increasing
this value will brighten the sound.
RESO (Resonance) 0–100
Adjusts the amount of resonance (tonal character) of the
sound. Increasing this value will produce a more strongly
distinctive tonal character.
DETUNE Adds depth to the sound by layering a pitch-
shifted sound.
-1OCT Adds depth to the sound by layering sound
one-octave lower.
