Vienna Symphonic Library Synchron Strings Pro Standard Library is a virtual instrument with a library that accurately captures the sound and expressiveness of fourteen 1st violins, ten 2nd violins, eight violas, eight cellos, and six double basses. Expertly performed by the members of the Synchron Stage Orchestra and recorded with the signature ambience of the Synchron Stage Vienna scoring stage, this powerful and versatile Pro version offers a wealth of detailed articulations with an abundance of choices and a multitude of presets in an instrument that's easy to use right out of the box. The result elevates these string ensembles to the next level of liveliness and expressive potential needed for authentic musical performances and dramatic scoring.

The Synchron Strings Pro Standard Library includes a few articulations from Synchron Strings I (staccatos, legatos senza and molto vibrato, long notes, flautandos, and more), but most articulations are new recordings with special attention to attack and release variations, and natural note transitions. Agile legatos—including portamento, spiccato, détaché, expressivo—let you play all imaginable runs and figures in all tempos, with the natural flow and authentic note transitions automatically provided by the included Synchron Player.

The short notes category includes new spiccatos (shorter, more pointed variants to the staccatos), bold staccatos (for slower tempos) and agile staccatos (for faster tempos), as well as détachés that can be played as originally recorded or shorter, thanks to the Synchron Player's evolved release trigger technology.

Legato transitions were added to the flautando playing technique to make this very soft sound available for melodies. Sforzatos, crescendos, and diminuendos can also be played shorter than their recorded length, which makes them usable for a wide range of applications. Ponticello (staccatos, sustains, legatos, tremolos), col legno, and harmonics round out the rich palette of included playing techniques.

The string sections were recorded separately at their designated positions onstage. Engineers employed four separate phase-coherent microphone configurations recorded simultaneously. All mic configurations can be mixed to create a range of room-sound options, each with different levels of ambience and stereo panorama.
