Linux PCs Drive 74-Channel Pipe Organ
cyberman11 writes "According to the EE Times, Marshall & Ogletree LLC have created an electronic simulation of a classic Aeolian-Skinner pipe organ in the Trinity Church situated, just 600 feet from ground zero near the World Trade Center site in New York. The system consists of 10 Linux PCs that drive 74 Carver amplifiers and 74 Definitive Technology speakers, for a total of 15,000 watts."
If you've seen a large pipe organ they can consist of thousands of pipes spread over a rather large area. The acoustic effect of having different tones coming from totally different areas of an auditorium is completely different than placing a hundred speakers throughout and having every one of them replicating the same sound.
There's more to it than that...but that's all I feel qualified to bring up.
check out http://www.hauptwerk.co.uk/ some of the larger organs (sampled pipe-by-pipe) require up to 1.5GB of ram to work and sound really good (check the site for samples esp. the ones of the commercial organ vendors).
