Strap yourself in for the Collision...

Collision is a unique instrument for authentic mallet sounds and creative percussion. Co-developed with AAS, it uses physical modeling technology to reproduce real-world instruments such as xylophones, marimbas and glockenspiels, but also provides enough depth to create truly dramatic new instruments and sounds. Unlike sampled instruments, this creates dynamic, living and breathing sounds that add an organic feel to your compositions. Corpus, a separate effect that reproduces Collision's resonator section, widens the scope even further, giving you a far-reaching sonic continuum from authentic, real-world sounds to exotic, experimental effects.

Key features

Co-developed with AAS, Collision is a completely new instrument, uniquely in tune with Ableton Live's workflow and intuitive user interface.
The comprehensive preset collection includes xylophone, glockenspiel, marimba, balaphone, vibraphone and toms.
Physical modeling synthesis allows you to tweak Collision's parameters in real time.
Exciter section: This has two oscillators. The first models the "beater," or whatever is used to hit the playing surface. By modifying the stiffness and the noise settings, you effectively control the beater material or type. For example, you can increase the stiffness to simulate a metallic beater or add noise to simulate a beater with a felt surface. The second oscillator in the Exciter section is a noise oscillator with envelope and multimode filter controls. This is great for getting creative and adding a unique edge to your sounds.

Resonator section: This features two polyphonic resonators arranged in series or parallel. These resonators model the playing surface and any additional resonating body. Choose from the following resonator models:
beam (a basic wooden or metal beam)
marimba (a beam that has been carved to produce a certain pitch)
string
membrane (the skin of a drum)
plate (a flat resonating surface)
pipe (open or closed)
tube (variation of pipe--always closed with additional tonal capabilities)

You can also control hitting and listening positions, decay, brightness and inharmonics. Each resonator type has its own parameters for controlling the virtual shape and size of the resonator:
ratio (controls the geometry of the membrane and plate resonators)
opening (controls the geometry of the pipe)
radius (lets you modify the size of both the tube and pipe resonator types)

Resonators have pitch envelopes featuring two LFOs with multiple modulation types.
Many parameters can be modulated via key tracking, velocity and MIDI controllers for expressive, dynamic playing.
