https://www.sonokinetic.net/products/instruments/ostinato-brass?ref=scl The phrase library for complex brass chords
Last year we released our Ostinato Strings library. It was designed to solve one specific issue that virtual instruments have struggled with for years: how to create realistic ostinato motifs without sacrificing playability. The library took our phrase-based approach and extended the harmonic scope so that far more complex chords than simple major and minors could be played.
Ostinato Strings was met with great acclaim both for the sound and the flexibility of the chord system, so we couldn't resist following it up with a brass section using the Ostinato engine and with the same intuitive features. We returned to the great recording space we employed for other Sonokinetic orchestral libraries and gathered a selection of some of the greatest (and most precise) brass players to perform for us.
The entire approach is different from our regular phrase instruments in that we recorded separate intervals for various rhythm building blocks. After careful editing we combine these intervals through an intelligent script that builds them into chords in 5 different voicings and up to 4 inversions (the fourth only for 7th chords).
Not only does the engine build the chords based on the inversion you play in the chord area, but when you play in the harmonic shift area it will judge which inversion it plays based on the chord that came before it, the chord quality on the key you're in and the position of the chord you're triggering in that key. This ensures that transitions are smooth and harmonically correct. 
Ostinato Brass recognises and plays 12 different chord types, handling not only major and minor chords but also diminished, half-diminished, augmented chords and many more. For a full list check the user manual.
This library coexists alongside both our Orchestral Series and our Phrase-Based libraries, being recorded in the same hall, with identical mic positions and even utilising some of the same players. Our orchestral libraries blend seamlessly together. 
We, at Sonokinetic BV, are very proud to introduce Ostinato Brass to you and can’t wait to hear the amazing things you, our valued customer base, will produce with it.
Sonokinetic has established a name as one of the best value & quality sample producers and with this product we’d like to underline that statement. We stick with our unbeatable pricing module and high quality sampling. We wish you the best inspiration and creativity.
