Use Ultrabeat oscillator 2 phase oscillator mode
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 dierence is that Saturation can be modulated in oscillator 2, rather than Asymmetry in
oscillator 1. This results in the production of dierent 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 on page 358.
Create classic waveforms with Ultrabeat’s phase oscillator
The basic waveforms of classic analog synthesizers can be reproduced with the phase
oscillator: sine, rectangular, and sawtooth waves will result from dierent Slope, Saturation, and
Asym parameter value combinations.
Do one of the following:
m To produce a classic square wave, set Slope and Saturation to their maximum values and Asym to
the minimum value.
m To produce a sawtooth wave, set Slope to −0.20, Saturation to the minimum, and Asym to the
maximum value.
m To produce a sine wave, set Slope, Saturation, and Asym to 0 values .
