• Click a button on the lower edge of oscillator2 to select a mode (synthesizer engine).
Use Logic Pro Ultrabeat oscillator1 phase osc mode
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 Logic Pro Ultrabeat oscillator2 phase osc 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 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
Logic Pro 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.
