Vienna Instruments - Special Brass from the Vienna Symphonic Library is a sample-based virtual instrument, that covers the more esoteric, but none the less essential elements required, when writing for orchestral brass.
Instrumentation includes "Fanfare Trumpets" (six players,) that provide impact with their sforzato and sforzatissimo playing techniques. Also included are solo cornet, an alto trombone that expands the VSL trombone family to its highest register, and a euphonium.
The Vienna Instruments user interface is clearly arranged and includes pre-configured patches for immediate playability with no learning curve. The interface uses a powerful proprietary streaming audio engine that can load up to 3,456 articulations (patches) on one MIDI channel.
Load times are extremely low and sixty-four stereo voices per instance can stream from the hard disc. A RAM optimizing utility clears unused samples out of RAM. Users can easily create their own instruments, using "drag and drop" functionality, and the instrument provides the ability for velocity crossfades and release control to be switched on or off in real time.
