Vienna Symphonic Library Synchron Duality Strings Ostinato Virtual Instrument Library (Standard Library)

Both ensembles—the large section in Stage A and the more focused group in Stage B—performed extensive ostinato passages together, perfectly in sync. From these recordings, individual notes were meticulously extracted and are now reassembled in real time by the Vienna Synchron Player, delivering authentic transitions, natural variation, and a realism that feels truly performed rather than programmed.

And because you’re working with single notes rather than fixed patterns or locked tempos, every rhythm, tempo, and contour is entirely your own. With short notes, long notes, and expressive legatos at your disposal, you can even go far beyond ostinatos to create everything from driving rhythmic engines to lyrical string passages.

Every articulation in this library is optimized for ostinato performance. Using the articulation sequences in the Vienna Synchron Player, it’s easy to play different consecutive bowings, from simply alternating between up and down strokes, to more complex patterns that mix up- and down-bow spiccatos with détachés. The Synchron Player provides preconfigured sequences with various patterns, but of course you can easily create your own.

• Spiccatos with up and down bows
• Short and long détachés
• Legatos
• 8 variants of intervals and 8 variants of repititions for spiccatos and détachés
• 5 variants of intervals and 5 variants of repititions for legatos

As with all Duality Strings collections, you can seamlessly blend the spacious, cinematic sound of the large ensemble in Stage A with the articulate, close-miked detail of the smaller ensemble in Stage B. Both groups were recorded simultaneously in their respective rooms at Vienna Synchron Stage, with the conductor in Stage A also directing the small ensemble via video monitors.

This unique setup allowed the musicians to hear each other across rooms and perform in perfect sync, aligning every aspect of their playing—volume, timbre, note length, and phrasing. Combined with numerous microphone positions, this approach gives you remarkable freedom to sculpt the precise character your ostinato needs: lush and wide, tight and driving, bright and cutting, warm and rounded, intimate and chamber-like, or bold and epic for powerful rhythmic engines. It’s an organic, highly flexible way to merge the resonance of a full ensemble with the immediacy of a smaller group—all inside one musical performance.
