and Knob [2] OSC1 Mod: Waveform
Knob [3] Control1: Waveform [000...127]
Knob [1] Wave: Saw
The sawtooth wave is appropriate for cre-
ating a wide range of sounds typical of ana-
log synthesizers, including basses and pads.
Adjusting the value will modify the shape
of the waveform, changing the harmonic
content. A setting of 000 produces the origi-
nal sawtooth wave. Higher setting stress
different harmonics; a setting of 127 pro-
duces a sawtooth wave one octave higher.
000 063
Knob [1] Wave: Pulse
This is a pulse wave suitable for electronic
sounds and wind instruments. By adjust-
ing the pulse width you can produce
sounds reminiscent of clavi or sax. A set-
ting of 000 produces a simple square wave.
Higher settings narrow the pulse width,
and at a setting of 127, the pulse width will
disappear completely (no sound).
000 063
Knob [1] Wave: Triangle
Triangle waves have fewer overtones than
sawtooth or square waves, and are suitable
for mild tone such as bass or pads. Adjust-
ing the value will modify the shape of the
waveform, changing the harmonic content.
A setting of 000 produces a simple triangle
wave. Higher setting stress different har-
monics; a setting of 127 produces a triangle
wave that is one octave and a fifth higher
28
(i.e., the third harmonic).
000 063
Knob [1] Wave: Sine
Sine wave is a mild tone that contains only
the fundamental frequency with no over-
tones. A setting of 000 produces a simple
sine wave. Increasing this value will
modify the waveform, changing the over-
tone structure as shown below.
000 063
Knob [4] Control2: LFO1 Intensity [000...127]
127
LFO1 will vary the "OSC1Ctr1" effect
(Waveform Modulation.) "OSC1Ctr2" ad-
justs the depth of this change.
When Knob [1] Wave: Formant
and Knob [2] OSC1 Mod: Waveform
Knob [3] Control1: Formant Width
The formant waveform has a tonal charac-
ter reminiscent of a human voice. This
knob will adjust the frequency components
that are characteristic of vocal formants.
127
This is equivalent to changing the shape
of your mouth (i.e., changing the vowel
sound).
Knob [4] Control2: Formant Shift [–63...+63]
Moves the entire formant frequency spec-
trum upward or downward. This is equiva-
lent to changing the size of your mouth.
With a setting of 0, the formant locations
are unchanged.
When Knob [1] Wave: Noise,
and Knob [2] OSC1 Mod: Waveform
Knob [3] Control1: Resonance [000...127]
127
Adjusts the amount of resonance of the fil-
ter provided within the noise oscillator.
Higher values will emphasize the fre-
quency points for the pitched component
within the noise.
Knob [4] Control2: LPF/HPF Mix
[LPF63...CNT...HPF63]
Adjusts the mix balance between the low-
pass and high-pass filters; this will vary the
brightness of the sound.
When Knob [1] Wave: DWGS

Knob [3] Control1: ---
has no effect
Knob [4] Control2: Wave Select [001...64]
Selects the DWGS waveform.

*: The 48: Endless waveform simulates the "in-
finite staircase" sound which produces the
same perceived pitch in each different octave.
The "infinite staircase" produces the sensa-
tion that you never get any higher, no matter
how long you continue playing the notes C,
D, E, F, G, A, B, C, D, E, ? upward.
