CHAPTER 23. LIVE INSTRUMENT REFERENCE 363
23.2 Collision
The Collision Instrument.
Collision is a synthesizer that simulates the characteristics of mallet percussion instruments.
Created in collaboration with Applied Acoustics Systems, Collision uses physical modeling
technology to model the various sound generating and resonant components of real (or
imagined) objects.
The full version of Collision is not included with the standard version of Live, but is bundled
with the Corpus effect as a special feature available for purchase separately.
23.2.1 Architecture and Interface
Collision's sound is produced by a pair of oscillators called Mallet and Noise, which feed a
pair of independent (or linked) stereo resonators. While the oscillators produce the initial
component of the sound, it is the resonator parameters that have the greatest impact on
the sound's character.
Collision's interface is divided into tabs, which are further divided into sections. The Excitator
tab contains the controls for the Mallet and Noise oscillators. The Resonator tabs contain
the parameters for the independent resonator sections, while the Link tab allows you to
adjust both resonators simultaneously.
The LFO tab contains two independent low-frequency oscillators (LFOs), which can each
modulate multiple parameters. Similarly, the MIDI tab allows for MIDI pitch bend, modula-
tion wheel and aftertouch messages to be routed to multiple destinations.
To the right of the resonators is a section of global parameters, including overall output
volume, polyphony and resonator routing options.
