The waveform of the phase oscillator can be reshaped into almost any basic synthesizer waveform. The effects of parameter changes are immediately reflected in the waveform display. See Use Ultrabeat oscillator 2 phase oscillator mode.
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 gain, eventually causing the waveform to clip. Higher values make the waveform shape more rectangular. This results in a corresponding increase in odd-numbered overtones.
Asymmetry 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.
Note: The oscillator 2 phase oscillator operates in a nearly identical fashion to the phase oscillator of oscillator 1. The key difference is that Saturation can be modulated in oscillator 2, rather than Asymmetry (in oscillator 1). This means that when both oscillators are in phase oscillator mode, they can produce different sounds.
