Vienna Instruments PRO is a powerful sample player designed for orchestral music production, built on the renowned Vienna Instruments audio engine. It ensures full compatibility with all existing and future Vienna Instruments sample collections while introducing unique features that enhance realism and expressiveness. One standout innovation is the Humanize function, which injects subtle variations in timing and intonation to replicate the natural nuances of live musicians, elevating sample-based performances to new levels of authenticity.

This software offers extensive customization options that streamline the creative workflow, allowing users to tailor patches and articulations precisely to their needs. Up to eight instruments and articulations can be layered within a single matrix cell, with independent control over volume and panning, enabling complex multi-instrument setups and polyphonic legato playing. Additional tools like time stretching adjust sample lengths to match project tempo, while microtuning scales cover a broad range of musical traditions, including just intonation and various Arabic, Turkish, and Chinese scales, with the option to create custom scales.

Vienna Instruments PRO also features an internal Auto-Playback and Pattern Sequencer that triggers rhythmic patterns, arpeggios, and full orchestral arrangements in real-time, synced to the host tempo. This function offers inspiring starting points for composition or quick orchestration ideas. The software includes fast sample loading, a new browser with search capabilities, built-in reverb and equalizer, and a modern user interface with both basic and advanced views. Its efficient memory management and intuitive articulation handling make it a comprehensive solution for detailed orchestral sample playback.
