Motherboard.tv has an article on what is probably the world’s largest synthesizer (let’s not forget T.O.N.T.O) created by Joe Paradiso over about twelve years starting in 1974. It has recently been installed at MIT. What is amazing is that you can listen to long audio files of patches that Joe creates every couple of weeks, or (now for the really crazy part) visit an online interface to literally control the synth remotely with other users doing the same thing!
