The most revolutionary feature in Session Horns Pro isn't a sample; it's an algorithm called Smart Voice Split.
Here is the technical problem: If you play a three-note chord (C-E-G) into a standard brass library, every instrument plays the exact same chord in the same octave. Trumpets play low C, Sax plays low C. This creates a muddy, unrealistic "block" sound. Real horn players don't do that; they spread the notes.
How Smart Voice Split works: When you play a chord, the engine automatically distributes the notes across the four instruments based on their natural ranges.
Result: You press three fingers on a keyboard, and out comes a perfectly voiced, professional horn section arrangement that sounds like an arranger wrote it for you. You can play block chords with your left hand and a melody with your right, and the engine divides the labor seamlessly.
The core of Session Horns Pro is its sample library. It is built on the foundation of the popular "Session Horns" (non-Pro version), but with a significant upgrade in detail.
The library features a four-piece horn section:
While the standard version offers these instruments, the Pro version records them with ten times the detail. The samples were recorded at the renowned Funkhaus studio in Berlin, capturing the natural room ambience. The result is a warm, punchy, and woody tone. Unlike some libraries that sound overly processed or dry, Session Horns Pro sounds like a band playing in a real room.
The dynamic range is impressive. You can play soft, breathy whispers or push the mod wheel to trigger loud, brassy swells that cut through a dense mix without needing heavy EQ. native instruments session horns pro
The ensemble trumpets are sampled as a pair. For a massive sound, duplicate the track, transpose it down one octave, and mix it in at 30% volume. This gives you a "French Horn" undertone without muddying the mix.
Session Horns Pro is a sampled horn section (trumpets, trombones, saxophones) designed for realistic arrangement without needing advanced brass skills. It ships as part of Komplete (Standard/Ultimate) or as a standalone purchase, running in Kontakt Player (no full Kontakt required).
Key strengths: Smart voice leading, chord memory, articulation switching, and a dedicated mixer with close/room mics.
Native Instruments Session Horns Pro is not a perfect emulation of a live brass section—no software can replace the chaotic, breathing energy of three or four jazz musicians in a room. But it is arguably the best practical solution for producers who need authentic, powerful, and flexible horn sections in their music.
Its genius lies in its user experience. By abstracting the complexity of horn arranging into the Smart Chord system, it opens up a world of brass textures to keyboardists, beatmakers, and composers who don't have the time or resources to hire a section. The sound is punchy, clean, and mix-ready. The articulation set covers 90% of what pop, funk, and R&B producers will ever need.
If you produce music in the realms of pop, hip-hop, rock, or electronic music and you have ever thought, "This track needs some horns, but I don't know how to write for them" — Session Horns Pro is your answer. It turns the impossible into the immediate. It’s not just a sample library; it’s a creative partner that lets you play the horn section you hear in your head.
Final Verdict: Highly Recommended for pop, funk, R&B, and hip-hop producers. A worthy addition to Komplete Ultimate. An example of smart software design that prioritizes musicality over technical complexity. The most revolutionary feature in Session Horns Pro
Native Instruments Session Horns Pro is highly regarded as a versatile, detailed virtual brass library specifically tailored for contemporary styles like pop, funk, soul, and jazz. Unlike orchestral libraries, it focuses on tight, bright, and dry small-scale ensemble sounds. Key Features and Strengths
Massive Sound Library: Boasts a 30GB library (ten times the size of the standard version) featuring ten instruments: three saxophones, two trombones, three trumpets, a tuba, and a flugelhorn.
Realistic Arrangements: The Smart Voice Setup automatically distributes voices across played chords to mimic how real brass sections are arranged, preventing the "muddy" sound of simple polyphonic playing.
Performance Tools: Includes the Animator, a phrase library with over 200 ready-to-play riffs that sync to your project's tempo.
Customizable Ensembles: You can build your own sections with up to six assignable slots, mixing and matching solo instruments.
Deep Articulation: Offers 34 articulations, up to four velocity layers, and true vibrato samples for high expressivity. Expert and User Insights
Sound Quality: Reviewers from Sound On Sound highlight its convincing and rich tones, particularly the raspy tuba and pure trumpets. MusicTech notes it as a significant upgrade from the base version for producers of horn-centric music. Result: You press three fingers on a keyboard,
Ease of Use: The interface is praised for making complex horn arranging accessible even to those with limited brass theory. Limitations:
Genre-Specific: It is not ideal for orchestral or big band compositions; its tone is strictly modern and "zippy".
System Requirements: Requires at least 6GB of RAM and significant disk space.
Phrasing: While powerful, some find integrating the pre-recorded Animator phrases into existing melodies can be cumbersome.
Subtleties: Some reviewers noted a lack of mechanical noises (like key-on/off clicks), which might affect realism in exposed solo parts. Summary Pros & Cons High-quality, clear, and bright samples High system and storage requirements (30GB) Intelligent auto-arranging for realistic sections Less suitable for orchestral or cinematic work Includes solo versions of all instruments High price point if not bought in a bundle Extensive articulation and effect options
Pre-recorded phrases can be hard to fit into complex melodies

Legato sounds realistic, but real section players tongue (articulate) most notes. If you play a line entirely in Legato mode, it sounds like a synth pad. Switch to Sustain for the melody and use Legato only for slurred jumps (e.g., a 5th or octave).
Unlike older libraries that simply crossfade between held notes, Session Horns Pro uses interval sampling. When you play a melody line (e.g., C to D), the script triggers a recording of a real player sliding or jumping between those exact two pitches. This eliminates the "sucking" sound found in crossfade-based legato.
