Cluster animated filter


Cluster is a plugin for creating complex, animated filter effects. At its core is a looping step sequencer that runs in precise sync with incoming audio and lets you set filter type, frequency and modulation envelope individually per each of its 32 steps. Thanks to such flexibility, as well as multiple filter models and finely-tunable parameters, Cluster can easily do anything from smooth, precise filter sweeps to rhythmic spectral reconstruction – regardless of what kind of sound is on the input.


Cluster displays a live audio waveform and aligns its sequencer graphics with it – exactly in the same way it’s done by the sound engine, for true “what you see is what you get” operation. Every element in its user interface is color-coded and features subtle animations, bringing unusual ease of use and interactivity. Plus, all this goodness is rendered right on your Mac’s graphics adapter meaning fast response and no extra load on the main processor, regardless of how new or old your system is.

– Filter matrix with low-pass, high-pass, band-pass and band-reject types.
– Thee filter modes: -12 dB/octave state-variable filter, -12 and -24 dB/octave biquad filters.
– Envelope matrix offering 10 envelope shapes, adjustable time and lag.
– Eight parameter snapshots in each preset, available for realtime switching and automation.
– Host transport synchronization with support for tempo and time signature changes.

– Live input audio waveform and fluid sequencer graphics visually matched to it.
– Support for multi-touch gestures and force touch on compatible trackpad devices.
– Fully hardware-accelerated rendering with support for Retina screen resolution.

– Works with any application that supports Audio Unit effect plugins.

It sounds wicked, and genuinely one-of-a-kind. [...] It's at its most useful spicing up drum loops, helping out with spot effects and serving as a sound design tool, and at this price, it's highly recommended – Future Music magazine, 2013
Cluster is a very simple effect with a surprisingly wide range of potential uses. [...] We'd call it a worthwhile purchase for anyone making any kind of electronic music – Computer Music magazine, 2013
