buzztrax aims to be a music studio that allows one to compose
songs using only a computer with a soundcard. If you've used
tracker programs like FastTracker, Impulse Tracker, or the
original AMIGA SoundTracker, that will give you an idea
of how one can sequence music in Buzztrax. The Buzztrax
editor uses a similar concept, where a song consists
of a sequence with tracks and in each track one uses patterns
with events (musical notes and control changes). In contrast
to other Tracker programs, tracks are not simply sample players:
a user can make a song using an arrangment of virtual audio
plugins that are linked together to create different effects.
Each of these machines can be controlled realtime or via
patterns in the sequencer.
