Hauptwerk 

Get access to a large virtual instrument library consisting of 150 third-party instruments and 30 symphonic organs. Choose between Baroque, Theater, Symphonic and Classical sound. Adjust sound pitch and temperament and select between 512 audio channels.

Hauptwerk is a complex pipe organ modeling and per-pipe sound shaping program. Hauptwerk includes a 30 stop English symphonic organ recorded from St. Anne's, Moseley in Birmingham, England. It also models all of the physical controls and functional details of a pipe organ. The main console screen shows you a photo-realistic representation of the console, and allows you full control over the virtual organ in the same way that you would control the original instrument.
