Frank Barknecht is a writer, software developer and sound/code artist living in Cologne, Germany. His favorite weapon of mass creation is Pure Data. He has been involved in the "Pd scene" since around 2001, where he is supporting new users through the Pd mailing lists and helps maintain the central code repository. He wrote a handful of Pd objects like the popular fluid~ soundfont synthesizer for Pd, but most of the time he concentrates on developing libraries of Pd patches, so called abstractions. These include the preset handlers Memento and SSSAD, the instrument collection RRADical, and a port of Karlheinz Essl's Realtime Composition Library for Max/MSP to Pd. During 2007 he was a fellow at the Soundlab of the Academy of Media Arts KHM in Cologne.
