8.2 Oscillators

Oscillators are the heart of every synthesizer. They produce the sound that is later shaped
by the filter and other components. The Waldorf Pulse is equipped with three oscillators,
each of which has different features.

Oscillator 1

Oscillator 1 delivers a periodic oscillation where you can determine waveshape and
frequency. The frequency is defined by the pitch of the notes that are sent via MIDI.
Maximum pitch is approx. 8,5 kHz. The following parameters are available:
Semitone
Tune
Shape
PW
PW stands for pulsewidth. If you select a square waveshape, you can determine its
pulsewidth. The value 0 is equivalent to a pulse ratio of 1%, the value 127 is
equivalent to 50%.
20
-48...+48 Determines the pitch of the oscillator in semitone
steps.
-32...+31 Fine-tunes the oscillator in increments of 64ths of a
semitone.
Determines the type of waveshape to be generated.
The following waveshapes are available:
Pulse: square with variable
pulsewidth
Sawtooth
Triangle
0...127 Determines the pulsewidth of the square wave. If you
select a waveshape other than pulse, than this
parameter has no influence on that waveshape.
PW=0
PW=127
