Muted brass is one of those colours that can make or break a cue. Get it right and a score suddenly has menace, melancholy or noir-ish cool; reach for the wrong sample and you're left with something thin and honky that never sits in the mix. If you write for picture, you already know how few libraries truly nail that straight-muted growl.
VSL is out to fix that with Synchron Brass (muted), a new bundle dedicated entirely to the sound of straight-muted brass — and it arrives with three brand-new trombone packs to round out the family.
Let's dive into what makes this a genuinely useful addition to your orchestral toolkit.
A Home for the Muted Sound
Until now, VSL's muted brass has been scattered across the Synchron Special Brass collection. Synchron Brass (muted) pulls it together into one dedicated family. Two Single Packs that previously lived under Special Brass — Synchron Trumpet (Bb, muted) and Synchron Trumpet Ensemble (muted) — have been moved across, and they're now joined by three fresh arrivals aimed at the low end of the section.
Three New Trombone Packs
The new instruments are Synchron Tenor Trombone (muted), Synchron Bass Trombone (muted) and Synchron Tenor Trombone Ensemble (muted). Together with the trumpets, that gives you a coherent muted brass section — solo and ensemble, high and low — all captured in the same room, so blending across the family feels natural rather than stitched together.
Recorded Where It Counts
As with the rest of the Synchron Series, everything here was captured on the large Stage A of VSL's Vienna Synchron Stage. That means the room, the mic positions and the sound stage all match the wider Synchron ecosystem — handy if you're already building templates around VSL's orchestral libraries and you want the muted brass to drop straight in.
The Details That Matter
- What's new: the Synchron Brass (muted) bundle, plus three new Single Packs — Tenor Trombone (muted), Bass Trombone (muted) and Tenor Trombone Ensemble (muted).
- Two versions: every pack comes in Standard and Full. Both deliver the same instruments and articulations; Full adds an extended set of microphone signals for more mixing flexibility.
- Runs in the Synchron Player: VSL's free Synchron Player hosts the library, so it fits neatly alongside the rest of your Synchron and Big Bang Orchestra content.
- Formats & compatibility: VST3, AU and AAX plug-in versions, supported on Windows 10 and later and macOS 13 and later.
- Section coverage: the moved trumpet packs plus the new trombones give you solo and ensemble muted brass across the register.
If muted brass has always been the weak link in your template, this is the tidiest fix VSL has offered yet — one family, one room, solo to ensemble. Shop Vienna Symphonic Library at Koala Audio to explore the Synchron range.
