Ostinato Strings: The phrase library for complex chords
Ever since we started developing phrase libraries (and we've done quite a few now), we've been wanting to expand the harmonic material these libraries could output. We've never really been able to go beyond standard major and minor chords with our recorded phrases. There are many reasons for this; because our phrases are recorded live as a whole rather than constructed from smaller pieces, because there are hardware limitations to user's computers and because there are limits to the recording time we can allocate to a specific product while still keeping it affordable. Some of our products do contain different material, and with the harmonic shift function there are ways to approach things like 7th chords and sus chords, but until now we didn't have a way to play all the chords we wanted and also offer different inversions of these chords.
At the heart of the Ostinato series there is an entirely new process that we've been developing for quite some time now. From the recording stage, 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 recognises and plays 12 different chord types, it is our first instrument that can handle diminished, half-diminished, augmented chords and many more. For a full list check the user manual.
This is the first product in this new line of instruments that will coexist alongside both our Orchestral Series and our Phrase-Based libraries, bridging the gap by doing on specific thing exceptionally well... ostinato chords.
