Chapter 14 Ultrabeat 341
Use Ultrabeat oscillator 1 side chain mode
In side chain mode, Ultrabeat uses an external side-chain input as the source for oscillator 1.
The signal of any audio channel strip, bus, or live input can be routed through Ultrabeat’s lters,
envelopes, LFO, and step sequencer. Using busses as side-chain sources makes it possible to
route signals to the side-chain input from any channel strip type that oers busses as outputs
or sends. This includes software instrument channel strips, aux channel strips, or a mix of
multiple channel strips that are routed into a common aux (subgroup), that has a bus as the
output destination.
This feature enables you to 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, for example. As another
creative option, you could use one drum sound in a kit to lter an external audio signal with a
sequenced groove.
There are two points to note about side-chain use in Ultrabeat:
•
The side chain aects only the selected drum sound—Ultrabeat’s other drum sounds and
sequences are not altered.
•
A side-chain audio signal alone is not enough to trigger Ultrabeat. To hear the side-chained
audio signal, you need to make sure that Ultrabeat is triggered by MIDI or the internal
step sequencer.
Use Ultrabeat’s side chain
1 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.
