Edit Screen (PG-200 screen)
DCO-1
Here you can select the waveform that determines the character of
the sound, and specify its pitch.
Selects the waveform that is the basis of the sound.
Waveform
(Sawtooth wave), (Square wave),
(Pulse wave)
Specifies the octave of the oscillator.
Range
64, 32, 16, 8, 4, 2
Freq Mod
Turns on/off the pitch modulation applied by the
LFO LFO to DCO-1.
Freq Mod Turns on/off the pitch modulation applied by ENV-1
ENV-1 to DCO-1.
MODULATION (common to DCO-1/2)
Here you can adjust the depth of the LFO and ENV-1.
Adjusts the depth at which the LFO pitch-modulates
LFO Mod
DCO-1/2.
Adjusts the depth at which ENV-1 pitch-modulates
ENV-1 Mod
DCO-1/2.
DCO-2
Selects the waveform that is the basis of the sound.
Waveform
(Sawtooth wave), (Square wave),
(Pulse wave), Whitenoise (Noise)
Specifies the octave of the oscillator.
Range
64, 32, 16, 8, 4, 2
Tune Adjusts the DCO-2 pitch in semitone units.
Fine Tune Finely adjusts the DCO-2 pitch.
Freq Mod Turns on/off the pitch modulation applied by the
LFO LFO to DCO-2.
Freq Mod Turns on/off the pitch modulation applied by ENV-1
ENV-1 to DCO-2.
Metal: Uses DCO-2 to control the output signal
of DCO-1, producing a sound reminiscent of ring
modulation.
Cross Mod
Sync: Generates a waveform in which DCO-2 is
synchronized to the oscillator frequency of DCO-1.
Off: DCO-1/2 operate independently.
LFO
Here you can create cyclic change (modulation) in the sound.
(Sine wave),
Waveform
RND (Random wave)
Specifies the time from when the key is pressed until
Delay
the LFO's amplitude reaches the maximum.
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).
If this is ON, the envelope starts repeatedly at
Trig ENV
intervals of the LFO cycle.
VCF
This is a low-pass filter that passes the low frequencies and cuts the
high frequencies.
Source Mix
Adjusts the DCO-1 volume.
DCO-1
Source Mix
Adjusts the DCO-2 volume.
DCO-2
Specifies the cutoff frequency of the low-pass filter.
Cutoff Freq Frequency components above the cutoff frequency
are cut.
Resonance boosts the sound in the region of the
filter's cutoff frequency.
Resonance
Higher settings produce stronger emphasis, creating
a distinctively "synthesizer-like" sound.
Adjusts the way in which the pitch of the note
affects the cutoff frequency (key follow) when using
Pitch Follow the keyboard to control cutoff frequency. Moving
the knob to the left causes the cutoff frequency to
fall as you play higher range on the keyboard.
Velocity
Adjusts the sensitivity by which the low-pass filter is
Sens affected by keyboard dynamics.
Envelope (ENV-1/ENV-2)
Here you can create time-varying change (envelope).
Attack Attack time
(Square wave),
Decay Decay time
Sustain
Sustain level
Release Release time
6
Screen Structure
Adjusts the amount by which the LFO modulates the
LFO Mod
VCF cutoff frequency.
Adjusts the amount by which ENV-1 controls the VCF
ENV-1 Mod
cutoff frequency.
Specifies the cutoff frequency of the high-pass
filter which cuts the low frequencies and allows the
HPF
higher frequencies to pass. The frequency region
below the cutoff frequency is cut.
VCA
Here you can adjust the amount of time-varying change (envelope)
for the volume.
Velocity
Adjusts the sensitivity with which the volume is
Sens affected by your keyboard dynamics.
GATE/ENV- Selects whether volume change is controlled by
ENV-1, ENV-2, or the gate signal.
