5. OSC1
(Oscillator 1
When Knob [1] Wave:
Saw, Pulse,
Triangle, Sine
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.
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).
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
(i.e., the third harmonic).
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.
Knob [4] Control2: LFO1 Intensity [000...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.
This is equivalent to changing the shape
of your mouth (i.e., changing the vowel
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]
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
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
and Knob [2] OSC1 Mod: Waveform
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.

Knob [4] Control2: Balance
Sets the balance between the L channel
([AUDIO INPUT 1]) and R channel ([AU-
DIO INPUT 2]) jacks.
