Granular synthesis revolutionized Sound Design, Electronic and Experimental Music. crusher-X does advanced granular synthesis on your live input in real-time!

crusher-X granular synthesizer and effect plug-in for Windows (VST 2.4 32bit and 64bit) and macOS (AU, VST 64bit)

Its powerful algorithm creates very complex sounds, drones and outstanding surround effects. The crusher-X trademark is known since 1999 as "the" granular effect standard. crusher-X is used by famous sound-designers, composers, musicians and film-makers all over the world. The professional, open-minded and curious "crusher-X community" creates outstanding, unique, multi dimensional sonic pieces and thrilled their enthused audience in great live-shows.

Features: Over 130 presets, stereo and 10 channel surround outputs (e.g. 5.1, 6.1, 7.1, 8.2, 9.1), Up to 199 grain streams that are processed multi-threaded (Multi-Core CPU support). Advanced parameter editor with physical modeling faders and an unique physical modeling X/Y controller. 3D grain visualization, over 240 free assignable real-time plug-in parameters, real-time MIDI control, morphing system, parameter phase and frequency spread modulations (spreading modulations over several grain stream generators), modulation and grain quantization to host, pitch tracking and autotune system with keyboard input and visualization, long real-time grain lengths, individual grain overdrive, filtering, unique X-crush and Diffuse grain processing. Shadow programs. Unlimited undo/redo and randomize functionalities. Several granulation live buffer and freeze modes. Automatic triggered grain buffer filling modes. MIDI Polyphonic Expression (MPE) support. Comes with hundreds of different tuning scales and MIDI keyboard control of grain effect.

crusher-X is the secret weapon for sound designers. Giving birth to unusual, uncategorized, never heard sounds flow, grain walls, drone walls, sonic explorations – that’s why granular synthesis exists. crusher-X unique multichannel surround sound feature is designed to make film scores outstanding. The “inner consistency” of grains that are modulated and smeared in phase and frequency over 10 surround output channels is the reason why composers are using crusher-X for their next level score.

For this purpose the qualification „beautiful“ or „ugly“ makes no sense for sound, nor for the music that derives from it; the quantity of intelligence carried by the sounds must be the true criterion of the validity of a particular music.
Iannis Xenakis in "Formalized music: Thought and mathematics in composition.", 1963-1992

The crusher-X algorithm is based on the traditional granular synthesis algorithm (Xenakis, Roads, Wilkins) invented in the early 1950s. In granular synthesis, short (e.g. 50 milliseconds) sound fragments, "the grains," come from a fixed file buffer. The starting time, length and silence between the grains can be modulated. More than one grain at a time is possible, so you can create complex sound "clouds" from any sound signal. 

When experimenting with those (length of grains), I have discovered a certain confusion as to what effect one can expect when setting parameters to certain values. Not only it seemed that length and density each had an impact of its own on the character of the granulated sound, but it also appeared that their relational value was highly important.
Leon Zadorin "Composing with Granular Synthesis"

A "window function" blends in and blends out the grains at the begin and end of its live cycle. This function determines the character of the continuum and thus the different perceptions. Xenakis recommended the Gaussian window because of its theoretical considerations. For performance reasons, e.g. Truax realized in its real-time systems simple linear-interpolated envelopes.

All sound is an integration of grains, of elementary sonic particles, of sonic quanta. Each of these elementary grains has a threefold nature: duration, frequency, and intensity. All sound, even all continuous sonic variation, is conceived as an assemblage of a large number of elementary adequately disposed in time. (...) Hecatombs of pure sounds are necessary for the creation of a complex sound.
Iannis Xenakis in "Formalized music: Thought and mathematics in composition.", 1963-1992

In opposite to the “classic” file based approach, the crusher-X algorithm provides a floating grain buffer which allows real-time input and output. In this floating buffer the grains are created by several generators routed to several outputs (stereo or surround). One can apply many very unusual parameters to the grains such as Speed, Filter, Pan,  X-Crush, Overdrive or Diffuse  - all modulated with independent modulation sources and modulation phases, synchronized or not synchronized to the plug-in host. The accSone grain processing algorithms X-Crush, Overdrive and Diffuse are unique in the world of granular synthesis. A feedback loop can gerenate very complex and non-linear sounds.

A complex sound may be imagined as a multi-colored firework in which each point of light appears and instantaneously disappears against a black sky. But in this firework there would be such a quantity of points of light organized in such a way that their rapid and teeming succession would create forms and spirals, slowly unfolding, or conversely, brief explosions setting the whole sky aflame. A line of light would be created by a sufficiently large multitude of points appearing and disappearing instantaneously.
