Tenebra offers a huge variation of sounds, from solo instruments recorded in their studio to full-scale orchestral sessions from world-class stages, all meticulously processed to create their signature sonic identity. More than 100 sounds, split into Bells & Glass, Drones, Guitar Dulcimer Citole, Humanity, Orchestral, Percussion, Synths, Woodwinds and Warps, expertly crafted into over 130 presets by the Newton Brothers themselves. .
Synths:
A vast suite of pulses, pads, and aggressive textures sourced from The Newton Brothers' personal synth collection. Sounds were created using an ARP 2600, Moog Matriarch, DFAM, Prophet Bass, Polygogo, Lyra, Theravox, Oberheim X, Folktek Resonant Garden, Folktek Mescaline, Super Gemini, Solar 42 and an expansive Eurorack modular system. This category forms the electronic backbone of the library, featuring everything from evolving pads and surreal realities to growling pulses.
Presets include: Surreal Reality, Dark Pulses, A Computer's Heartbeat, Haunting Synth, Prehistoric Dinosaur Coffee Morning, and the ominous warped presets Falling Shards and I Made A Mistake.
Ethereal Voices & Winds:
A raw, intimate collection of haunting vocal and wind textures that blur the line between human and unearthly. Morphed choirs, pained whispers, and unique global instruments combine to provide the library’s most chilling sounds in the form of evolving pads and otherworldly leads. This includes the ethereal "Black Flute" (a custom bass ocarina) blended with vocals, siren phrases, and flutter textures. It also features processed human vocals, alongside unconventional instruments like the Southeast Asian Khaen and various bird flutes.
Orchestral Mutations:
The traditional orchestra, deconstructed and re-imagined. This category features full-scale orchestral recordings—from strings to the rare Nocturna—warped into ghostly textures, chaotic gestures, and unsettling risers. Presets include: Purgatory’s Cello, Evolving String Chaos Swells, Ghost Bends, Bendy Violins, Unsettling String Drones, Crazy Collegno FX, and Insane Textures & High Gliss.
Drones & Atmospheres:
Build psychological terror with a wide range of atmospheric beds and drones. The foundation of slow-burn dread. A wide range of atmospheric beds designed to create a palpable sense of unease, from organic, airy textures to complex, multi-layered synth drones. Featuring presets like Breath Drone, Creepy Wind Screams, Fluttery Drone, Howling Wind Kit, Alpha Wave (Solar42), and deep, resonant Bass Drones.
Unconventional Instruments & Percussion:
A selection of uniquely performed instruments, including a bowed medieval Citole, bowed Dulcimer, and a "perfectly imperfect bowed piano". The percussive elements feature a trio of drums, resonant garden percussion, and the iconic Waterphone, presented as deep booms, soft hits, and unsettling moans. Presets include: Perfectly Imperfect Piano, Citole Bowed Harsh, Bowed Dulcimer Kit, Glass Bottle Kit, and Trio Drum Rolls.
