Orchestral Tools has introduced a new SINE player-powered instrument library featuring a selection of playable acoustic sounds to evoke fear, tension, and unease.
Created in collaboration with Toronto-based composer and multi-instrumentalist Mark Korven, Korven offers a vast array of genuinely fear-inducing sounds, all created acoustically.
Stray from the path in the dark wood, or venture alone into the cellar in a strange house, and you’ll hear these sounds. Mark Korven (The VVitch, The Lighthouse, The Black Phone) understands like no one else the organic roots of real fear, and has developed a signature style based on acoustic instruments.
Korven captures Mark’s vision in a vast, terrifying, and inspiring orchestra—for folk horror, primordial dread, tense underscoring, and any kind of music that creates unease and apprehension.
Korven features
- 622 playable instruments and patches.
- Includes 49 layered instruments and 83 processed patches.
- Includes sounds from the Apprehension Engine.
- Includes specially orchestrated experimental strings and wind quintet.
- Includes the experimental 8-foot Symphonae instrument, hurdy-gurdy, oktav harpa, waterphone.

- Designed and recorded by Mark Korven at Revolution Recording in Toronto, Canada.
The library is on sale for the intro price of €129 EUR until November 11th, 2025 (regular €199 EUR).
