Ableton AG is a Berlin-based music software company that produces and distributes the production and performance program Ableton Live and a collection of related instruments and sample libraries, as well as their own software controller Ableton Push. Ableton was founded in 1999 by Gerhard Behles, Robert Henke of Monolake and Bernd Roggendorf. After Behles' work on granular synthesis features for Native Instruments' Reaktor, as well as earlier software using a Silicon Graphics workstation at the Technical University of Berlin, Live was first released as commercial software in 2001. Behles remains the chief executive officer of Ableton. Abletons office is located in the Mitte district of Berlin, Germany with a second office in Pasadena, California. In March 2007, Ableton announced it was beginning a collaboration with Cycling '74, producers of Max/MSP. This collaboration is not directly based on Live or Max/MSP, but rather combines the two companies' strengths in a new product.
