Trailer Brass — Free Download
Trailer Brass is a cinematic brass library for Kontakt with massive ensembles, aggressive processing, and a range of sound design tools.

Purpose and Concept
Trailer Brass is designed for modern, oversized cinematic scoring, contrasting traditional brass libraries. It captures three distinct ensembles: a ten-horn group, a ten-trombone group, and the Horde, a combination of three cimbassi and three tubas that has been aggressively processed for maximum impact.
The library includes a variety of sound design patches created from the brass recordings, such as impacts, pads, BRAAAMs, synth basses, and rhythmic drones. These patches expand the usability beyond traditional brass lines into hybrid scoring. The core goal is to provide a cohesive, over-sized sound palette that fits contemporary trailer and action music without requiring extensive tweaking from the user.
Key Capabilities and Programming
The instrument offers a range of articulations and patches. The Adventure and Majestic patches allow you to play believable brass lines using the keys and the modwheel for expression. Staccato and sustain patches provide additional options, and the Horde includes long and short marcato variations as well as two processed versions. Cluster effects are available for trombones, and there are eleven sound design patches derived from the brass recordings.
A notable feature is ‘Morph Stacking’ programming, which lets any note length sound natural, avoiding unnatural loops or cuts. The humanization control adds subtle variation to the performance, and the ‘To Silence’ feature enables niente dynamics, letting notes fade to silence effectively. With three microphone positions (Close, Room, and Mixed), users can shape the perspective within the recorded hall.
Workflow and User Interface
The library includes five different graphical user interfaces, each designed to immediately inform you of what a patch can do in terms of control. This approach reduces the learning curve and speeds up workflow, letting you focus on composing rather than programming. The controls are intentionally limited, with many patches requiring only keys and the modwheel to produce expressive brass lines.
The ‘Trailer’ series is part of a companion set; this brass library is a companion to Trailer Strings, meaning they were designed to work together in a trailer music context. Each section is recorded separately in centered and wide-seating formats, giving you flexibility in stereo imaging. The humanization and ‘To Silence’ features are particularly useful for creating realistic swells and fades, common in cinematic scoring.
Practical Applications and Summary
Trailer Brass is ideal for creating bold, powerful brass moments in trailer music, epic orchestral cues, action scores, and hybrid compositions. The ensemble sizes and processing are tailored for ‘over-sized’ modern film music. Use the Adventure and Majestic patches for melodic lines, the Horde for massive low-end punches, and the sound design patches for impacts and textures. The ‘To Silence’ feature allows for dramatic niente endings.
When composing, consider layering the mixed microphone position with room mics to achieve the full wall-of-brass effect. The cluster effects are useful for dissonant tension, while the rhythmic drones can underpin action sequences. For trailer impacts, the processed Horde patches give instant, aggressive hits. This library serves producers who need a one-stop brass solution for high-impact cinematic work, though it requires a full Kontakt 5.5.1 or higher.
