Well, Sonokinetic's generosity paid off this morning.
I was able to snag a free license for Ostinato Strings last week. Prior to doing so, I wasn't familiar with Sonokinetic.
I was impressed by Ostinato Strings, so I decided to purchase Sotto this morning.
Sotto sounds fantastic, and is unexpectedly deep for a phrase-based library. I could spend days experimenting with all the color combinations. And as a learning tool, I don't think I've ever seen another VI come close.
However (yes, there's a "but"), does anyone else find this library to be deceptively resource-intensive? According to Kontakt, there's rarely more than five or six voices playing. Nevertheless, I was initially getting almost constant clicks when transitioning between triads. Attacks sounded abrupt or cut off, and adjusting the note-on timing ahead of or behind the beat wasn't fixing the problem.
I was finally able to eliminate these problems by (A) raising the sample buffer size considerably (from 128—which usually works fine for my other Kontakt and VSL libraries—to 512) and (B) turning off SpeedStep on the CPU, a 3.4 GHz, 8-thread Haswell Xeon.
In this respect, Sotto joins Diva as the only VIs for which I have to take these measures for acceptable performance. Is this normal?
