The pitch of OSC1
Osc2
The pitch of OSC2

Note that both
F
Osc1
and
Osc2
can be selected simul-
taneously.
Oscillator (
Osc1
&
Osc2
)
The Oscillator is the source of your sound, where the basic
waveform is generated.
There are two Oscillators available, so that you can play
two waveforms simultaneously. Further than just combin-
ing the output of the two Oscillators, one oscillator can also
modulate the other, creating very complex and constantly
changing waveforms.
The two oscillators have slightly different features de-
scribed below.
Oscillator Waveform selector
The Waveform Selector button determines what type of
waveform is generated by the Oscillator.
If the waveform is of multi-type you can use the Wave-
form Selector dial to further select what waveform should
be generated. The LEd window will show the currently
selected waveform.
Please refer to “Oscillator Waveform Types” on page 20 for
more information.
Shape parameter (
shaPe1
&
shaPe2/dec
knob)
The Shape parameter is used for altering the waveform
generated by the Oscillator. The exact functionality varies
depending on what type of waveform is generated. Please
refer to “Oscillator Waveform Types” on page 20 for more
information.
seMi tOnes
knob
The
seMi tOnes
knob is used for changing the pitch of
Osc2
relative to
Osc1
in steps of semi tones, ranging from
-24 (-2 octaves) to +24 (+2 octaves) semi tones.
The red LED will briefly indicate a pitch setting of even
F
octaves.
fine tune
knob
The
fine tune
knob is used for changing the pitch of
Osc2
relative to
Osc1
ranging from -0.5 to +0.5 semi
tones.
While having an equal
F
Osc Mix
setting, and a
seMi
tOnes
setting of 0; slightly rasing or lowering the fine
tune parameter will produce a “richer” sound.
Oscillator Modulation (
Osc MOd
)
Oscillator modulation is all about having the waveform
produced by
Osc2
modulating
Osc1
.
Osc1
will produce a
richer waveform with more resonant harmonics the more
modulation you apply.
By changing the frequency of OSC2, you change the
F
harmonic content of OSC1 - not its frequency.

Low-pitched note
High-pitched note
This is the same principle as FM-synthesis (described on
page 21), but is far more powerful as you can have the os-
cillators set-up to produce any waveform you like - includ-
ing sample playback.
Also the waveform produced by
Osc2
can be heard by us-
ing the
Osc Mix aMOunt
knob.
There are two types of modulation available: Frequency
Modulation (
fM
) and Phase Modulation (
PM
).
Frequency Modulation (
fM
)
Frequency Modulation generates more frequency bands
and the resulting sound is normally perceived as rawer
and brighter. The harmonic content changes drastically
depending on in what note range you play.
