Spitfire Audio Chamber Strings: The Ultimate Guide to Intimate Orchestral Scoring

Spitfire Audio Chamber Strings (formerly known as BML Sable) is widely regarded as one of the most expressive and detailed orchestral string sample libraries ever recorded. Built on a 16-piece chamber ensemble configuration (4 1st Violins, 3 2nd Violins, 3 Violas, 3 Celli, and 3 Double Basses), this library stands apart from massive 60-player symphonic collections by delivering individual section definition, intimate bow texture, and agile articulation control.

Recorded in the world-famous Lyndhurst Hall at AIR Studios, London, the ensemble was captured using handcrafted Neve Montserrat microphone preamps, the iconic custom AIR Lyndhurst Neve 88R mixing desk, and pristine 2-inch Studer tape. This legendary analog recording chain imparts a luxurious warm room bloom, high-frequency air, and organic depth that integrates effortlessly into modern film scores, TV cue compositions, and contemporary pop productions.

Articulations, Expressive Legato, and the Ostinatum Engine

Spitfire Chamber Strings features an extraordinary depth of content, housing over 244 individual articulations across all sections. From standard sustains and rapid spiccato bowings to rare textural performance techniques—such as flautando, sul tasto, sul ponticello, con sordino, and double-bowed measure trills—composers can craft nuanced dynamic arrangements without needing secondary libraries.

The library's standout feature is its expressive true legato engine, scripted by Andrew Blaney. Capturing realistic bow change transitions, interval slurs, and dynamic vibrato swells, the legato patches allow melodic lines to sing naturally. Furthermore, Spitfire's proprietary Ostinatum engine lets composers generate intricate rhythmic arpeggios, driving pulses, and complex patterns instantly by playing simple chord progressions.

• Comprehensive Legato Patches: True legato with bow-change, fingered, and portamento transition modes.
• Extensive Short Bowings: Spiccato, staccatissimo, pizzicato, Bartók snap, and col legno.
• Unique Tonal Textures: Sul tasto, flautando, sul ponticello, and muted con sordino bowings.
• Built-in Pattern Generator: Ostinatum engine for rapid rhythmic ostinato creation.

Microphone Positions and Sonic Customization

The standard library provides three essential mic perspectives curated by award-winning recording engineer Jake Jackson: Close (C) for direct bow friction and high-frequency bite, Tree (T) for the classic stereo perspective of AIR Lyndhurst Hall, and Ambient (A) for lush room reverb tails. Composers can blend these positions to balance dry articulation definition against expansive hall acoustic space.

Because chamber ensembles possess smaller player counts, the sound cuts through busy mixes with surprising clarity. Where large symphonic sections can sound muddy or overly diffuse when layered with modern pop elements or synth bass, Chamber Strings provides sharp focus and harmonic definition while retaining true orchestral grandeur.

Who Spitfire Chamber Strings Is Built For

This library is an indispensable tool for film, TV, and video game composers who score drama, thrillers, neo-classical pieces, and emotional character cues where individual instrument textures matter more than sheer sonic volume. It allows listeners to hear the friction of horsehair on gut and steel strings, creating an immediate emotional connection.

It is equally valuable for contemporary pop, indie, and hip-hop producers who need authentic string arrangements that sit tightly in a modern track without crowding vocals or kick drums. Unlike drier studio string libraries, Chamber Strings brings genuine London hall acoustic character while remaining nimble enough for fast harmonic movements.

Best Practices for Layering and Realism

To achieve maximum realism and emotional impact when composing with Spitfire Audio Chamber Strings, experienced media composers rely on several proven MIDI programming and mixing techniques.

1. Ride CC1 (Dynamics) and CC11 (Expression): Automate both controllers simultaneously during melodic phrases to match natural human breath and bow pressure.
2. Use Dynamic Section Layering: Layer the Sul Tasto or Flautando patches underneath standard legatos during quiet passages for an otherworldly, ethereal warmth.
3. Double-Track for Symphonic Width: When a larger symphonic sound is required, record two slightly offset passes of Chamber Strings to create a rich 32-player section with pinpoint detail.
4. Blend Mic Positions: Set the Tree mic as your foundation (approx. 70%), bring in Close mics (approx. 20-30%) for transient definition, and add Ambient mics for natural reverb tail.
