Oscillator Section
The Oscillator section is available for synth zones.
The Oscillator section offers six sound sources: three main oscillators, the sub oscillator,
the ring modulation, and the noise generator. To create interesting electronic spectra, you
can mix any of these sound sources. The resulting signal is sent to the Filter and Amplifier
sections for further sound shaping.
The three main oscillators (OSC 1, OSC 2, and OSC 3) offer different wave shapes and
algorithms.
• To activate an oscillator, click its On/Off button.
OSC 1/2/3 Type
The oscillator type defines the basic sound character of the oscillator. This pop-
up menu lists the waveforms (sine, triangle, saw, or square), followed by the
algorithm (PWM, Sync, CM, or XOR). The combination of waveform and algorithm
controls the sound of the oscillator.
The following algorithms are available:
• PWM (pulse width modulation) is only supported by the square waveform.
The Waveform parameter sets the ratio between the high and low value
of the square wave. A setting of 50 % produces a pure square wave. With
settings below or above 50 %, the oscillator produces rectangular waves.
• Sync provides different hard-sync oscillators, where each is a combination
of a master and slave oscillator. The wave shape of the slave oscillator
(sine, triangle, saw, or square) is reset with each full wave cycle of the
master oscillator. This means that a single oscillator can produce a
rich sync-sound without using other oscillators as slave or master. The
Waveform parameter adjusts the pitch of the slave oscillator, producing the
typical sync sound.
• CM (cross modulation) provides a combination of two oscillators where
a master oscillator is modulating the pitch of a slave oscillator (sine,
triangle, saw, or square) at the rate of the audio sample. The Waveform
parameter adjusts the pitch ratio between slave and master oscillator,
resulting in a sound close to frequency modulation.
• XOR (exclusive OR) compares two square waveforms with an XOR
operation. Depending on the outcome of the XOR operation, the waveform
shape of a third oscillator (sine, triangle, saw, or square) is reset. The
Waveform parameter adjusts the pitch ratio of the square oscillators
resulting in a sound close to ring modulation of the third oscillator.
