Orchestral Brilliance

Our proprietary sample player Vienna Instruments Pro comes with every VI Series library*, free of charge.

Vienna Instruments Pro allows you to combine hundreds of articulations on one MIDI track, and switch easily between them. Our proprietary Performance Detection analyzes intervals, repeated notes, patterns, and even playing speed in real-time, and automatically summons the appropriate articulation or nuance.

Vienna Instruments Pro improves your workflow dramatically, making your creative process faster and easier, and also adding human behavior to your music. Customize all presets and articulations to your preferred way of creating music, stack multiple instruments in a single instance of Vienna Instruments Pro, play them with polyphonic legato, and breathe even more life into the samples by controlling the performance accuracy of your virtual musicians in real-time, at the touch of a single fader.

Retina Announcement

Super fast loading-times, auto humanization, polyphonic legato, enveloped time stretching, adjustable tuning scales, built-in reverb and EQ, and a straight user interface with basic and advanced views – among so many other cool features – come together to create a powerhouse of orchestral production that will add life to your music in ways you never imagined.

*) Please note that only VI Series Collections, Single Instruments and the VI Special Editions can be loaded into Vienna Instruments Pro. Our Synchron Series and SYNCRHON-ized libraries as well as former sample libraries of the First/Pro Edition, the Horizon series or 3rd party libraries (e.g., for Native Instruments’ Kontakt) are not supported. The VI Series' piano library Vienna Imperial comes with its own free sample player.

**) The full scope of phrases and runs is available for registered users of all Vienna Instruments Collections (Full Libraries). Since the Standard Libraries and the VI Special Editions don’t include many of the more advanced articulations for certain musical phrases, these products are limited to using the preconfigured chords of the APP sequencer
