Sonora Cinematic has announced the release of a deeply detailed chamber string library that brings a premium cinematic string experience to Audiomodern’s Soundbox platform and the subtle, yet distinctive, internal motion that real ensembles naturally create.
Those who use string libraries to write for film, TV, or cinematic music, will be all too familiar with the issue of long, sustained notes often sounding too static or too clean. Movimento Strings was created to address this problem.
At the heart of the library is an exceptional 12-piece ensemble featuring 3 first violins, 3 second violin, 3 violas and 2 celli and 1 bass.
Focusing on the tiny variations that give real string sections their organic movement such as players rebowing at slightly different times, dynamics gently fluctuating, tone colours constantly shifting within sustained notes, Movimento Strings delivers the natural, living textures that bring that extra sense of motion to music.
The library features four articulations:
- Free Bowing – Instead of all players changing bow direction simultaneously, each musician rebows independently creating a rich, blurred and beautifully organic sound.
- Free Bowing Slow – Uses the same independent bowing technique, but with less frequent bow changes, ideal for slow emotional cues and evolving harmonic beds.
- Free Bowing Flautando – The independent bowing technique is combined with flautando playing, where the bow is placed closer to the fingerboard, resulting in an airy, delicate tone with a soft, flute-like character.
- Dynamic – Each player performs independent crescendos and decrescendos on the same note. This creates a beautifully undulating texture where the sound constantly evolves while the pitch remains unchanged.
Movimento Strings is available in two versions. The Standard edition renders each of the four articulations into a ready-to-play mix that sounds great right out of the box. Users can simply load any of the twenty patches (which include single section and full ensemble patches) and start writing. The Professional edition adds advanced tools like multiple mic perspectives for each articulation and an ‘EXTRA’ performance pass allowing users to effectively expand the ensemble with six more players while keeping it natural and organic-sounding.
Movimento Strings for Soundbox (v1.2 or higher) is available to download now from the Sonora Cinematic website at introductory pricing starting from £19 GBP (ex. VAT where applicable). The offer expires May 5th, 2026.
