Sonora Cinematic has launched the Penombra Celli and Penombra Viole software instrument libraries. These additions to the Founders Locker line utilize processed recordings from the Movimento Strings series.
Why it matters
The company developed these libraries after determining that the original session recordings possessed high production quality. By layering these takes with synths and treated audio, the developer aimed to provide new textures for composers.
Each library is priced at £10.80 including VAT. Users must have at least version 1.3 of the Audiomodern Soundbox software to run the instruments.

Audiomodern
This company provides the proprietary Soundbox software platform required to host and execute the new instrument libraries.
The details
The libraries feature processed audio designed to capture a brooding tone in the lower registers with the Celli and a restless quality in the middle range with the Viole. Both instruments support MPE features and run exclusively within the Audiomodern Soundbox environment.
Timeline
The Penombra Celli and Viole libraries were released on October 13, 2026.
Industry Dynamics
The release continues the developer's trend of utilizing the Movimento Strings series, following a pattern set by its previous sample-based software collections. This approach highlights the ongoing industry strategy of re-processing legacy high-fidelity studio recordings into specialized, affordable digital tools.
Users can access these instruments by purchasing them through the developer's storefront for use in the Soundbox software. Prospective buyers must ensure they have updated their host software to version 1.3 or later to ensure compatibility.
The takeaway
Composers looking for specialized string textures can integrate these tools into existing Soundbox workflows at a low entry cost. Those interested in the specific sounds should audition the Celli for brooding low-end needs or the Viole for middle-register movement.
