A few weeks from now, the VSL Synchron Strings (part I) will be released. And some time after that — "very soon", the website says — the library will be powered by an all new Vienna Synchron Player, a "dedicated sample player with a brand new engine built from the ground up. Its innovative new algorithms make it effortless to render strings with astounding realism".
VSL Synchron has 8 velocity-layers, 80 variations per key, captured through 8 separate phase-coherent microphone configurations.
If you order VSL Synchron Strings before it's released, you qualify for a 30% reduction of the full list price. Currently, there's also a 30% promotion going on for VSL's other string libraries.
