-<p>A track's type is really only related to the type of data that it stores on disk. It is possible, for example, to have a MIDI track with a synthesizer plugin which converts MIDI to audio. Even though the track remains ‘MIDI’, in the sense that its on-disk recordings are MIDI, its output may be audio-only.</p>

+<h3 id="busses">Busses</h3>
+<p>Busses are another common concept in both DAWs and hardware mixers. They are similar in many ways to tracks; they process audio or MIDI, and can run processing plugins. The only difference is that their input is obtained from other tracks or busses, rather than from disk.</p>
+<p>One might typically use a bus to collect together the outputs of related tracks. Consider, for example, a 3-track recording of a drum-kit; given kick, snare and overhead tracks, it may be helpful to connect the output of each to a bus called ‘drums’, so that the drum-kit's level can be set as a unit, and processing (such as equalisation or compression) can be applied to the mix of all tracks.</p>
