Osc Page

The Osc page contains the parameters for the three main oscillators.

  • 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, and Square, followed by the algorithms PWM, Sync, CM and 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 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 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 wave shape of a third oscillator 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.

Level

Adjusts the output level of the oscillator.

Waveform

Modifies the sound of the oscillator algorithm. Its effect depends on the selected oscillator type.

Note

This parameter is only available for oscillator types that allow waveform modulation.

Filter Envelope

Determines how much the modulation of the filter envelope influences the oscillator waveform.

Note

This parameter is only available for oscillator types that allow waveform modulation.

Tuning

These parameters allow you to adjust the pitch in octave, semitone, and cent steps.

Multi Oscillator Number, Detune, and Spread

  • Number determines the number of oscillators that play back simultaneously. You can also set fractions of numbers. For example, with a setting of 2.5, you hear two oscillators at full level and a third one at half level.

  • Detune detunes the oscillators.

  • Spread narrows or widens the stereo panorama. With a setting of 0 %, you create a mono signal, and with 100 %, you create a stereo signal.
