Apparat is a German electronic musician (Sascha Ring) living in Berlin and one of the owners of Shitkatapult records. Starting out with dance floor-oriented techno, he later started to create ambient music and more recently became "more interested in designing sounds than beats". Recent music is closer to glitch or IDM, accompanied with classical string instruments and other sounds. The website Apparat.net features a few Max/MSP patches, presumably used by him.   Wikipedia
