Cluster

Cluster is a multi-filter sequencer. The core concept is simple at first – a filter with a modulation envelope – but every single parameter is sequenced in a rhythmical fashion, even the filter type itself. At the foundation of the sound engine is a set of six filters which can be selected from many models like multi-mode state variable, comb, phaser and resampler; also, each of those filters can be configured with up to 4 stages in series.

Based on this setup, Cluster builds up a sequencer matrix with 7 parameter lanes: three for the filters (type, frequency, resonance), and four for its highly flexible envelope generator with over 50 possible modulation shapes. The sequencer matrix holds up to 8 patterns at once and is driven by an elastic step sequencer algorithm with both polymetric and polyrhythmic abilities, and an extremely wide range of timing settings.

All of this is presented via a single-screen, color-coded user interface with dozens of utility functions for pattern manipulation – which makes Cluster an extremely easy-to-use and fun tool for creating pretty much any animated filter effects you can dream of... and way beyond.

Sound Engine

• Six-track filter sequencer with type and slope selectable per track; independently variable cutoff frequency and resonance per step.
• 9 available filter types: low-pass, high-pass, band-pass, notch, peaking, comb positive and negative, phaser, resampler; up to 4 filter stages with self-calibrating resonance.
• Multi-envelope generator for filter cutoff modulation with independently variable type, divisions, polarity and modulation level per step.
• Up to 8 separate sequences per preset.
• Step sequencer with up to 32 steps, rhythmically correct swing, polymetric and polyrhythmic abilities.
• Optional RMS limiter per each filter track.
• Variable per-step pan randomization.
• Two-pole analog-style lag filter for variable smoothing of all step transitions.
• One-pole lag filters on all continuous parameters for smooth, click-free adjustment.
• Supports mono › mono, mono › stereo, and stereo › stereo channel configurations.

Graphic Interface

• Color-coded graphic elements.
• Consistent name, mapping, value, and unit implemented for all parameters in both graphic user interface and host control/automation.
• Sequencer pattern macro editing functions: copy, paste, reset, trim, invert, shift, evolve, randomize, loop region.
• Built-in preset management functions.
• Supports window size scaling up to 200%.
