Spitfire Symphony Orchestra Discover is a free orchestral virtual-instrument library published by Spitfire Audio. The library is a curated subset of Spitfire Audio’s flagship orchestral collection, packaged in a compact, accessible format. Rather than including every instrument, articulation, and detail from the full premium library, SSO Discover presents a carefully selected set of instruments and sounds designed to give users a broad orchestral palette with minimal system requirements.
The library offers 44 carefully selected instruments and ensembles spanning strings, woodwinds, brass, percussion, harp, piano, and more. This selection gives composers access to a full-orchestra sound without the size and complexity of a professional-grade library.
For expression and articulation, SSO Discover provides a variety of playing techniques, including sustained notes, pizzicato, tremolo, staccato, and other standard articulations. These articulation options enable users to create dynamic, evocative orchestral passages and add realistic variation to their compositions.
The release of SSO Discover is significant because it dramatically lowers the barrier to entry for orchestral composition and arrangement. Previously, realistic orchestral sample libraries often required significant investment in money, storage, and computing resources. SSO Discover — being free, compact, and easy to run — gives musicians, producers, composers, and hobbyists a way to experiment with orchestral textures, cinematic atmospheres, or classical elements without large commitments.

Because the orchestral sound is professionally recorded and the instruments and articulations are carefully chosen, SSO Discover can serve a wide range of purposes: from sketching orchestral ideas, writing demos, producing underscoring for video or games, to adding orchestral flavor in song productions or ambient music. The ease of access helps democratize orchestral production for a broader audience.
Moreover, SSO Discover builds on the earlier free offering from Spitfire Audio — BBC Symphony Orchestra Discover — which had already introduced many users to orchestral sampling. The new release expands the instrument and articulation range, giving even more creative possibilities to users worldwide.
