Ableton AG is a German 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 hardware controller Ableton Push. Ableton's office is located in the Prenzlauer Berg district of Berlin, Germany, with a second office in Pasadena, California. History Ableton was founded in 1999 by Gerhard Behles and Robert Henke, who together formed the group Monolake, and software engineer Bernd Roggendorf. After Behles' work on granular synthesis 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. 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. In January 2009, the Ableton/Cycling '74 product "Max for Live" was announced. "Max for Live" makes it possible to create Max/MSP patches directly inside of Live. The patches act like other plug-ins in Live do, supporting preset saving, automation, and other features. It is possible to create both customized hardware plug-ins and patches as well as actions within those plug-ins that control every aspect of Live, essentially anything that can be clicked with a mouse. Ableton holds many music production sessions and seminars to learn to use their software, and licenses "certified Ableton trainers." In April 2015, Ableton published the hardcover book Making Music: 74 Creative Strategies for Electronic Music Producers written by Dennis DeSantis who is the Head of Documentation at Ableton and formerly a sound designer for Native Instruments. The work is organized according to three main categories: Problems of Beginning, Problems of Progressing, and Problems of Finishing and aims primarily to address "the non-technical aspects of the process of making music." While it shows images only of Ableton Live, the information is not specific to Ableton Live. In June 2017, Ableton acquired Cycling '74, developers of the digital signal processing environment Max/MSP and its integrated version Max for Live. In the first quarter of 2018, Ableton Live 10 was officially released, and the release of the new version added some new features to Ableton Push 2, including a new melodic step sequencing layout and MIDI note view.
