Mercury Symphonic Black Friday pricing is 50% off, so this Soundiron boys' choir for Kontakt comes to $199.50 until Dec 6, 2026.

The library is built from the Pacific Boychoir, boys aged 8 to 13, recorded in the same hall Soundiron used for its Olympus choirs, Mars and Venus. A chorus of 25 singers sings traditional Catholic Latin, and the maker says it is the most comprehensive children's choir sampled to date.

What is in the Mercury Symphonic Boychoir?

The articulation list is long. These are the main pieces:

  • 42 marcatos with deep round-robin and pp/fff dynamic layering
  • 42 staccatos with 4x round-robin, plus pp/fff layering on 6 core vowels
  • 18 tempo-synching Latin polysustains with legato and 2x round-robin releases
  • True legato vowels (Ah, Oh, Oo, Eh, Ee, Mm) with pp/ff layering
  • A classic ensemble whistle legato and unique fff poly-staccatos
  • Whispered, droned and spoken polysustains

There are also choral trills, sweeps and swells.

Two soloists join the ensemble: a younger soprano and an older alto. Each has staccatos, poly-syllabic phrases and a fluid true legato vowel.

A bonus collection of ambient soundscapes, drones, pads and atmospheres is built from the original choir recordings.

How do the Phrasemaster and Wordmaster tools work?

Phrasemaster steps through a sequence of staccato or marcato syllables, moving to the next one each time you play a new note. You can store up to 16 sequences and trigger them in real time with automation or keyswitching.

Wordmaster is a graphical tool for picking from 42 words across two independent articulation layers. You can flip between staccato and sustaining marcato with a button or keyswitch.

The maker pitches it as instant word-building using hand-tailored content.

How is it recorded and mixed?

The mix comes from 12 large-diaphragm Neumann microphones, with wide pairs placed from 1 meter to 20 meters away. Those are blended into two room positions, stage and hall, which the maker designed for easy surround mixing and low resource use.

Sustaining articulations include 3-part polyphonic pseudo-legato, and integrated DSP effects and custom convolution impulses come with every preset.

Format and requirements

This is a standard Kontakt open-format library with 57 Kontakt 4.2 presets and 35 Kontakt 5.1 presets. The install is 15.5 GB with 14,605 samples at 24 bit / 48kHz uncompressed PCM wav.

The full retail version of Kontakt 5.1 or later is required. In the free Kontakt Player it runs in demo mode only. Kontakt 4 owners on version 4.2.4 can load the 4.2 presets, though those lack the tempo-synching and time-stretching features.

The system requirements are Windows XP or higher or Mac OS X 10.6 or higher, a dual-core CPU and 4 GB of RAM. The maker recommends a SATA or SSD drive.
