Use an Ultrabeat side chain
1. In MainStage, turn on the side chain for oscillator1.
2. Choose the channel strip that you want to use as the side chain input source from the
Side Chain pop-up menu at the top of the plug-in window.
3. Start playback of your audio source/host application.
4. Play a note on your MIDI keyboard (that corresponds to the side chained drum sound).
Alternatively, you can use the step sequencer to play a pattern for the side chained
drum sound.
Use MainStage Ultrabeat oscillator2 phase osc 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 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
MainStage Ultrabeat modulation overview.
