Rosegarden is an open-source Linux MIDI, Audio sequencer and Notation editor, originally created for a university project in 1992 and is still going strong over 30 years later. The current incarnation of Rosegarden for Linux was kick-started in 2001 by Chris Cannam, Guillaume Laurent and Richard Bown. In this talk, one of the original creators of this legendary piece of OSS history takes you through the project's history and analyses some of the critical elements for its continued success to this day. The 'current' version of Rosegarden was actually a complete bottom-up rewrite that started in 2001. The previous incarnation (Rosegarden 2.1) was initially written for IRIX and then ported to other UNIX variants, including in 1995, Linux. The current version has not significantly changed since its original architecture was settled in 2001-2004. What's so good about it that keeps it working to this day? How many people are working on it now? And what do current users think of the project and where is it going next? Join Richard for an entertaining and exciting ride through Linux audio history as well as the history and architecture of Rosegarden.
