Signal Interrupted Expansion Pack (for Atmosia)

Broken comms, twisted messages, half heard and overheard conversations of alien noises. A twitching pulsating set of haunting communications from across the spectrum that drift in and out of range, tantalisingly unobtainable and at the edge of understanding. Perfect for adding that feeling of the just out of reach, the narrowly missed information and the sense of longing and regret it inspires. Powered by Atmosia: Harness the engine's full potential for unmatched depth and character. Containing 30 presets for the mighty Atmosia 3.

Brood Resurrection Expansion Pack (for Atmosia)

Some sounds don't just set a mood — they haunt. Rebuilt from the bones of Channel Robots' iconic Brood library and forged inside Atmosia, this is cinematic darkness at its most visceral. Unsettled textures, ritualistic drones, and decaying resonance coil beneath the surface — ready to unnerve, unsettle, and consume. Horror. Thrillers. Trailers. Wherever dread lives, Brood Resurrection belongs. Containing 30 presets powered by Atmosia — depth and character without limits.

Orbital Systems Expansion Pack (for Atmosia)

A forward-thinking sound set built around rich granular textures that feel alive, kinetic, and otherworldly. Each sound is crafted from evolving particles, fractured harmonics, and shifting atmospheres that orbit between precision and chaos—perfect for cinematic scoring, experimental electronic music, ambient sound design, and futuristic game audio. From drifting pads and pulsing beds to unstable drones and crystalline motion, Orbital Systems invites you to sculpt depth, movement, and emotion at the molecular level of sound. Containing 30 presets for the mighty Atmosia 3.

City of Keys Expansion Pack (for Atmosia)

A versatile sound set inspired by the rhythm and emotion of urban life, centered on expressive piano-like keyboard tones that range from intimate and delicate to warped and cinematic. Blending classic acoustic character with dissonant soundscapes, each sound captures the nuance of touch, space, and movement—perfect for songwriting, film scoring, lo-fi, pop, and electronic production. From almost-warm keys and moody nocturnal broken pianos to bright, cutting leads and alternative strings, City Of Keys turns every chord progression into a story unfolding across the skyline.

Alarm Semaphores Expansion Pack (for Atmosia)

A high-tension sound set inspired by alarms, warning signals, and the creeping sense of impending dread. Built from piercing tones, distorted pulses, and anxious rhythmic patterns, each sound feels like a system pushed to failure—urgent, mechanical, and impossible to ignore. Ideal for sci-fi scoring, industrial music, horror, and trailer sound design, Alarm Semaphores communicates danger through sound, transforming alerts and sirens into cinematic signals that keep listeners on edge.

Poly Plaits Expansion Pack (for Attracktive)

The Digital Rebel, Now in Full Harmony. When Mutable Instruments launched Plaits in 2018, it redefined the Eurorack landscape — a monophonic macro oscillator armed with 24 versatile synthesis models and a proudly digital soul. Beloved for its raw, unmistakable character, it quickly became an essential tool for modular synth enthusiasts. When Mutable Instruments closed its doors in December 2022, demand for its iconic creations only intensified, sending used prices soaring. Poly Plaits takes that singular voice and multiplies it, delivering a lush, full‑blown polyphonic experience. It's not here to blend in — it's here to be heard. 100 Presets – 3000 Samples – 300 MB for BioTek 3 and Attracktive.

Forever 7 Expansion Pack (for Attracktive)

Iconic FM electric piano sound generator. Few sounds define digital synthesis like the DX7's electric piano presets — glassy, shimmering and instantly iconic. Forever 7 captures that magic with a curated collection of electric piano patches sourced from Yamaha's FM powerhouses: the DX7, DX7 II, SY77, FS1R, and more. But we didn't stop there – we stacked them with textured layers from 4-op synths like the TX81Z, DX21, and even the quirky SFG-05. The result? Patches that sound vintage yet fresh with plenty of harmonic depth and textural nuance. If you love FM pianos, this is your dream set. 100 presets – 14,000 samples – 3.9 GB for BioTek 3 and Attracktive.
