The waveform of the phase oscillator can be reshaped into almost any basic synthesizer waveform.
Oscillator 2 operates in a nearly identical fashion to oscillator 1 when in phase oscillator mode. The key difference is that Saturation can be modulated in oscillator 2, rather than Asymmetry in oscillator 1. This results in the production of different sounds when both oscillators are in phase oscillator mode.
Phase oscillator parameters
Slope knob: Rotate to set the slope or steepness of the waveform. The higher the value, the steeper the waveform. The resulting sound takes on an increasingly nasal character as the incline becomes more vertical.
Saturation slider: Move to increase the gain, eventually causing the waveform to clip. Higher values result in a distortion of the waveform shape, making it more rectangular. This results in a corresponding increase in odd-numbered overtones.
Asym(metry) slider: Move to change the waveform angle. Higher values skew the waveform toward a sawtooth wave. Asym can be modulated by the sources shown in the mod and via pop-up menus, enabling dynamic sound changes at the oscillator level. See Ultrabeat modulation overview.
The basic waveforms of classic analog synthesizers can be reproduced with the phase oscillator: sine, rectangular, and sawtooth waves will result from different Slope, Saturation, and Asym parameter value combinations.
Do one of the following:
To produce a classic square wave, set Slope and Saturation to their maximum values and Asym to the minimum value.
To produce a sawtooth wave, set Slope to −0.20, Saturation to the minimum, and Asym to the maximum value.
To produce a sine wave, set Slope, Saturation, and Asym to 0 values .
