Gethen is a cinematic Kontakt library focused on motion. It is built around a custom dual-line arpeggiator engine, designed to generate arpeggios, evolving phrases, rhythmic sequences and aleatoric textures in real time. No pre-recorded loops: hold a group of notes and let the engine do the rest.

From delicate neoclassical string ostinatos to granular vocal choirs, percussive metallophones and synthetic pulses, Gethen transforms simple input into intricate,
layered movement.

With 150+ sound sources spanning acoustic strings, voices, tuned percussion and electronic textures, and over 1,100 presets ready to drop into your session, Gethen gives film composers and sound designers an immediate palette of kinetic, cinematic sound, plus drag-and-drop support for your own samples, so the engine grows with your workflow.

THE SOUNDS

Gethen's 150+ sound sources span solo strings, woodwinds, vocals, bowed metals, plucks, synths and textural layers, all organised into sustains and shorts, each behaving differently when fed through the arpeggiator engine. Organic sources were recorded as multi-sampled instruments with chromatic mapping, round robins and dynamic layers. Designed sources were crafted using advanced spectral manipulation techniques in Kyma, a sound design environment used extensively in Hollywood scoring and post-production. Many sounds blend both approaches, sitting in a space between the realistic and the surreal: familiar enough to feel cinematic, strange enough to feel new.

THE ENGINE

At the core of Gethen are two independent arpeggiators, each driving its own sound layer. Set tempo-synced rates, note sequences and step patterns as you would with any arpeggiator, then go further: merge and slice steps, mute and unmute divisions within a line, and shape measures that break free from rigid repetition. What sets the engine apart is how it responds to what you feed it. Load a sustained violin or a soprano vocal and it behaves as a rhythmic granular engine, carving movement out of long tones. Load a spiccato, staccato or percussive hit and it switches to a dynamic sequencer, triggering precise rhythmic patterns. The engine detects the sound type automatically, no configuration needed (no pre-recorded loops or phrases, what you hear is built live from raw sound sources and your input). Layer the two arpeggiators together (any combination of granular and sequenced, or two of the same) and the result is intricate, non-static patterns from a single held chord. But the real power is in how the engine adapts to your playing. Voice through a progression by holding some notes and moving others, and the arpeggio reshapes in real time around your playing. You're not triggering a preset pattern, you're steering it.

THE PRESETS

Gethen ships with over 1,100 ready-made patches (snapshots) that pair sound sources with arpeggiator configurations, effects and tempo settings to give you production-ready patterns
from the first note. Snapshots are organised by category: Hybrid Violin, Cello, Viola, Textural Strings, Wind Phrases, Vocals and more. Each category contains variations across tempos, straight and triplet divisions, and different pattern styles. The same source sound can yield dozens of distinct cues depending on how the engine is configured, so every category runs deep. Browse by instrument, by tempo or by sound quality (tempo synched or free-form) and use any snapshot as a starting point to shape into your own.
