From the horse’s mouth (i.e. website):
The BBC Symphony Orchestra plugin by Spitfire Audio is a wonderful entire orchestra in a single plug-in. Given the patience to sequence out multiple tracks, it is a very convincing sounding! BUT….. What if you would like to play it LIVE? All 5 String Sections, all 5 Woodwind sections AND all 5 Brass Sections, on the keyboard, ready to knock your socks off? There is only 1 way to pull this off and then change to another of over 180 variations/combinations of these instruments = In Unify! And this is just the beginning!
DiscoverStation/CoreStation offer:
183 Patches combining instruments from the BBC Symphony Orchestra to make playable multi-instrument Patches.
There are 382 MIDI Files covering both modern productions as well as classical production styles in meters including 3/4, 5/4, 7/8 and 15/8!
There are many different applications in this library for how to use these Patches. Everywhere from simply playing the entire string, brass or woodwind section in realtime to MIDI Files playing elements with realistic techniques for use in all sorts of musical applications.
