Chapter 29 Ultrabeat 567
Once you select Side Chain mode for Oscillator 1, you need to select which channel
you wish to use as your side chain input. You do this in Ultrabeat as you would with
any plug-in with side chain input by choosing the desired channel in the Side Chain
menu.
Side Chain mode greatly expands your creative options when using Ultrabeat. You can
use an audio input from Oscillator 1 along with the synthesis engine of Oscillator 2 to
create a part live audio, part synthesized drum sound. Since Ultrabeat’s other drum
sounds and sequencer operates normally, you can blend analog drum programming
and side chain processing—for example, setting up one drum sound to step filter
external audio input to a programmed groove.
Note: A side chain audio signal alone is not enough to trigger Ultrabeat’s processors. To
hear the side chain audio signal Ultrabeat needs to be triggered by MIDI or its internal
step sequencer.
Unique Properties of Oscillator 2
Oscillator 2 can be switched between three different types of synthesis engines: Phase
Oscillator, Sample, and Model. This can be done by clicking the appropriately labeled
buttons at the lower edge of the Oscillator 2 section.
Phase Oscillator
Oscillator 2’s phase oscillator operates nearly identically to the phase oscillator of
Oscillator 1. The difference is that when in Phase Oscillator mode, Saturation can be
modulated in Oscillator 2 instead of Asymmetry in Oscillator 1. This means that when
both oscillators are in Phase Oscillator mode, they can produce different sounds.
For all other details of Phase Oscillator mode, please see “Phase Oscillator” in the
“Unique Properties of Oscillator 1” section.
