Brass II is a comprehensive collection within the Symphonic Cube series, featuring a rich selection of brass instruments essential for orchestral and cinematic music production. This set includes a variety of instruments such as piccolo trumpet, bass trumpet, triple horn, horn ensemble, bass trombone, contrabass trombone, contrabass tuba, Wagner tuba, and cimbasso. The collection offers both solo and ensemble performances, delivering the depth and character needed for authentic brass sections.

The library provides an extensive range of articulations and performance styles, including interval and repetition performances with legato, marcato, portato, staccato, crescendo, and diminuendo variations. Solo instruments feature grace note performances and trills in different intervals, while the horn ensemble offers blared sustains and dynamic swells. Additional expressive options such as flutter tongues and various vibrato styles enhance realism and musicality across both short and long notes.

Powered by the Vienna Instrument Engine, Brass II benefits from a highly efficient streaming audio system designed for seamless playability. It supports thousands of articulations on a single MIDI channel with fast load times and low resource usage thanks to real-time sample decompression and RAM optimization. Integrated performance detection and flexible control options allow musicians to trigger complex articulations and layer sounds intuitively, making this collection a powerful tool for detailed and dynamic brass arrangements.
