Buzztrax is a free software project designed to create a clone of the Buzz music composer.

Songs are made by adding virtual sound generators and effects, connecting them, recording short musical phrases and arranging them in the sequencer.

In the middle of 2002, the main developer, Stefan Kost, lost a song during a Buzz session because of a software error.

As the sources of Buzz were known to be lost, they started a new project called Buzztard, and they registered on SourceForge.

A notable feature of version 0.6 is the editing journal that helps to prevent loss of data in the case of a crash.
