Osterhouse Sounds is a boutique Kontakt sample library company founded by cellist and composer Ben Osterhouse. What began as a personal outlet for string arranging and recording grew into a catalog of sampled instruments aimed at composers and producers looking for expressive, character-driven tools rather than polished orchestral staples.

The catalog leans heavily on strings and includes titles such as Pattern Strings, a collection of tempo-synced rhythmic fragments recorded on violin, viola, cello, and bass; Pathfinder Cello and Pathfinder Violin, phrase-based legato instruments that generate lines from input chords; Sospiro Strings, built around swells and sustained articulations; Penumbra Strings and Shadow Strings, which focus on darker, effected textures; and Ripple Cello, Cello Textures Evolved, Oscillation Strings, Secco Strings, English Bass, and Viola Da Gamba. The library also extends beyond strings with Piano Repetitions, Piano Overtones, and the drag-and-drop samplers Cell Sampler and Sea Sampler.

The brand is known within the Kontakt community for unusual recording concepts, scripted interfaces that shape performance rather than just layering articulations, and a small-studio aesthetic that favors tonal color over realism. Libraries are sold directly through the Osterhouse Sounds site and through third-party retailers including Best Service, Loot Audio, and Plugin Boutique.

Ben Osterhouse has 15 products cataloged on Equipboard, including Kontakt Instrument. Most Ben Osterhouse products fall in the mid-tier range — professional-grade without flagship pricing.
