REAKTOR SPARK – 20
4.1 Oscillators Section
The main source of waveforms in SPARK is controlled with the Oscillators section.
The a
MplituDe
K
nob
controls the amplitude of the output signal of the Oscillator section. This
applies to both the mixed signal and the Sine output signal that goes directly to the Mixer
section.
The
p
lS
-S
ine
M
ix
K
nob
determines the main characteristic of the sound source. It acts as a
crossfader between the Pulse and Sine Oscillators for the mixed output signal. Turning the
p
lS
-S
ine
M
ix
K
nob
to the right yields a sound with a softer character typical of a sinus tone.
Turning the p
lS
-S
ine
M
ix
K
nob
to the left mixes more of the Pulse signal to the output, result-
ing in a brighter timbre.
The Static
pW K
nob
you can use to further change the timbre of the Pulse signal. It controls
the static amount of the Pulse width of the Pulse oscillator. With the Knob set in its vertical
position, a symmetrical Pulse signal with only odd harmonics is generated. Turning the Static
pW K
nob
either to the right or to the left, the Pulse becomes more asymmetrical, adding even
harmonics to the spectrum. The difference between turning to the left or to the right can be
very strong if the
pW K
nob
is not set to zero.
The p
itch
V
alue
e
Dit
found on the left of the Static pW K
nob
and a
MplituDe
K
nob
controls the
pitch of the Pulse and Sine Oscillator, respectively, when the Note C3 is played. Clicking and
dragging the
p
itch
V
alue
e
Dit
to the left of the decimal point transposes the oscillator pitch in
semitones. To fine tune the oscillators, click and drag to the left of the decimal point in the
p
itch

. Slightly detuning one oscillator from the other yields a fatter sound. Below
the p

lies the p

for the corresponding oscillator pitch.
This controls the response of the oscillator pitch to the MIDI note that is played. When set
