Iron Pack 4 - Children's Choir: Kontakt Choir Instrument by Soundiron

The core of the library is a set of Ah and Oo choir samples recorded with Mercury Boys' Choir, delivered as 24-bit / 48 kHz uncompressed WAV files. The Kontakt interface gives you a multi-layer control set with LFO, filter, glide and arpeggiator sections, so you can shape how the voices swell, move and sit in a mix.

The 11 Ambience patches are built from the same source material, which makes them useful when you want the choir to blend into a bed rather than sit out front. Together with the 12 SFZ presets, the 63 stereo samples give you a range of starting points.

A full FX rack sits alongside the instrument, and the convolution reverb includes custom rooms, halls, chambers and FX environments. The 20 Custom Sound-Designed FX presets, made for Kontakt 5.5 and later, offer ready-made treatments if you want to move quickly from a raw vowel to a finished texture.

The library installs at about 327 MB, a manageable footprint for a sample-based choir instrument.
