Virtual E.M. Skinner Organ
The organ at Zion Lutheran Church is a virtual E.M. Skinner 3-manual and pedal organ controlled by the state-of-the-art Hauptwerk™ virtual instrument software developed by Martin Dyde – from Milan Digital Audio. The incredible realism of the organ is attributed to the multi-channel audio system which splits the digitally sampled pipe ranks amongst many different speaker systems. The organ boasts 16 channels of audio - output to 24 channels of amplification.
By using the Hauptwerk™ system, the organ is able to replicate the complexity of swell enclosures, tremulants, air flow turbulence, and tuning drift – making the instrument sound convincingly like a real (and costly) pipe organ. The computer, with its Intel Quad-Core processor and 8 gigabytes of system memory is able to provide the very high polyphony necessary to model this very large pipe organ.
The organ has 3787 “virtual” pipes, 54 ranks in 4 divisions.
About the digitally sampled pipes:
Most of the ranks in the organ are digitally sampled from the 1928 E.M. Skinner, Opus 719 – at Our Lady of Mount Carmel Roman Catholic Church in Chicago, Illinois. It is one of the few E.M. Skinner organs that remains in nearly all of its original state. The samples are taken from inside the pipe chambers with microphones moving closely from pipe to pipe. Sample recordings were originally done in stereo at 24 bit, 96KHz direct to disk with the highest quality microphones and preamplifiers. The final sample resolution was converted to 24 bit, 48KHz. All pipe samples are 8-9 seconds with multiple sustain loops.
