Misc; Shape Parameter; Semi Tones Knob; Fine Tune Knob - Clavia Nord Wave User Manual

Misc

the Misc category is available in
oSc1 and contains a noise oscillator
algorithm.
Noise
When noise is selected, the oscillator produces, er, noise
rather than a pitched waveform.
the color (aka frequency content) of the noise can be
changed with a 12 dB/octave lowpass filter which is con-
trolled by the ShAPe1 knob.
the further you turn the ShAPe1 knob clockwise, the
brighter the noise. at the maximum setting, the frequency
content is very close to that of white noise (where all fre-
quencies are represented with equal energy).
Shape parameter (ShAPe1 & ShAPe2/dec)
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. this
is described for each different waveform on the previous
pages.
range: 0.0 to 10.0

Semi toNeS knob

the Semi toNeS knob is used to adjust
the coarse tuning of oscillator 2, relative
to oscillator 1. this is done in steps of semi
tones, ranging from -24 (-2 octaves) to +24
(+2 octaves) semi tones.
range: -24 to +24

fiNe tuNe knob

the fiNe tuNe knob is used for fine tuning the pitch of
oscillator 2 .
range: -50 to +50 semitones
•
If you have an equal oSc miX setting, and a Semi
toNeS setting of 0; slightly rasing or lowering the fine
tune value will produce a "richer" sound.
•
The red LED will light up when the pitch relationship
between the two oscillators is not in even octaves.
If oscillator 2 is detuned to oscillator 1 the LED will
have an inverted state. It will be lit all the time and
momentarily go dark when an even octave is selected
with the Semi toNeS knob.
Oscillator Modulation (oSc mod)
oscillator Modulation is about having the waveform pro-
duced by oscillator 2 modulating oscillator 1. oscillator 1
will then produce a richer waveform with more harmonics
and these will increase as you apply more modulation.
there are two types of oscillator Modulation available:
Frequency Modulation and Phase Modulation.
•
By changing the frequency of oscillator 2 when the
Oscillator Modulation is active, you change the har-
monic content of oscillator 1 - not its frequency.
6 Nord WaVE rEFErENCE
the waveform produced by oSc2 can be heard if you wish
by using the oSc miX AmouNt knob.
Frequency Modulation (fm)
Frequency modulation generates a wider spectrum and
the resulting sound is normally perceived as rawer and
brighter. the harmonic content changes drastically de-
pending on in what note range you play.
Low-pitched note
High-pitched note
the image above illustrates the harmonic content for a
low-pitched note and a high-pitched note using frequency
modulation.
Low-pitched note
F
High-pitched note
Some notes can sound more or less out-of pitch using
high amounts of frequency modulation; this behavior
Low-pitched note
is considered normal.
High-pitched note
Phase Modulation (Pm)
Phase modulation generates the same relative harmonic
content regardless of in what note range you play, and is
perceived as more fluent, similar to using keyboard track-
ing with the filter.
Low-pitched note
High-pitched note
the image above illustrates the harmonic content for a
low-pitched note and a high-pitched note using phase
modulation.

AmouNt knob

the AmouNt knob controls the amount of modulation.
range: 0.0 to 10.0

tyPe button

Press the type button repeatedly to activate and select the
type of modulation.
Settings: off, frequency modulation (fm) or phase modu-
lation (Pm).
