The Vienna Instrument Engine:

• Powerful proprietary streaming audio engine, developed by Vienna Symphonic Library's Christian Teuscher.
• Up to 3,456 Articulations (Patches) on one MIDI channel.
• RAM pre-load of up to 25,600 stereo samples (based on 1.6 GB available RAM under Windows; 48,000 samples on a 3 GB Mac G5).
• 64 stereo voices per instance streaming from disk.
• Extremely low load times (average 1 sec. per Patch) using pre-caching.
• Lossless real-time de-compression for using less RAM and hard disk resources.
• RAM Optimizer kicks unused samples out of RAM.
• Pre-configured Patches.
• Performance Detection algorithms integrated in Patches without the need to switch manually between articulations.
• Trigger comprehensive sets of articulations using hardware controllers (MIDI learn), key switches, and speed, without ever leaving the current MIDI channel.
• Layer Articulations for simultaneous or crossfade performances in one Preset.
• Easily design your own Instruments using Drag & Drop.
• Switch Velocity Crossfades and Release Control on/off on the fly.
