The Master machine is very important to all Buzz songs, as it is the final device before output to the audio card (or in some cases Hard disk) is made. Only one master machine may exist per song, as it not only controls the final output. Another useful feature of the Master machine, is its inherent control over the BPM (Beats Per Minute) and TPB (Ticks per Beat) of the current song.

Scripting the master machine is done in the exact same was as scripting all other machines.

Note: The Master is added when a new song is created and may not be deleted or duplicated.
