Sonokinetic has announced the release of a new Kontakt Player-powered instrument library that plays rhythmic Ostinato chordal patterns for a string quartet consisting of a cello, viola and two violins.

Ostinato Quartet delivers the initimate, direct and pure sounds of expressive string quartet recordings.

If you’re familiar with the sister Ostinato libraries and our approach to ostinato recording then you’ll feel right at home with Ostinato Quartet. The entire approach is different from our regular phrase instruments in that we recorded separate Ostinato patterns for various rhythmic building blocks. After careful editing, we combine these through an intelligent script that builds them into chords in 5 different voicings and 4 inversions. The new inversion arpeggio controls create inversion patterns at the press of a key… a fast and easy way to build interesting sequences.

Ostinato Quartet recognises and plays 12 different chord types, handling not only major and minor chords but also diminished, half-diminished, augmented chords and many more. There’s a full list documented within the user manual.

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, especially important to creating evolving motifs.

Regularly priced 99.90 EUR, Ostinato Quartet for Kontakt and the free Kontakt Player is on sale at a limited time 33% discount until December 26th, 2023.
