I don’t think anyone else does phrase libraries the way Sonokinetic does. And the libraries are reasonably well designed for what they do. (I say reasonably because much of the keyboard functionality is complex, even convoluted.) I agree with many that the general Ostinato libraries are harder to use in practice for some weird reason, even though their design is simpler. But I think they nailed Ostinato Noir, maybe because it allows chords other than triads.
The single one I don't have and will wait for 12 days of Xmas to get it.
I was telling I had an issue with the 49 keys can't do it, so well, I expand with another one or a pad. You just need an octave.
The idea is really great but the curve is really high, because you feel that punching a chord and then doing a whole progression "with one finger" seems like a jukebox.
But the curve, I think, it's focused on being able to split the sections, change phrases and also change the orchestration sections in between while you go with the progression, so you feel like the guy doing cartoon sounds in the 50's.
But here's the sauce, it doesn't matter much, because the idea is getting the ostinatos structure and then exporting them and then forget that library and load your one and keep doing it. Not the triplets, accents, the whole chords and harmony is there too.
So that's why Ost Noire complements the tool with extended chords. You can indeed have a SUS4 chord as I and it will assist you with the whole harmony progression up to the VII.
Like OPUS orchestrator, not for end game.
*don't forget that the sustain pedal on Ostinatos work as a latching switch, it will keep the chord playing when pressed.
