-<h3>Tracks are not Playlists</h3>
-<p>It is important to understand that a track is not a playlist. A track has a playlist. A track is a mechanism for generating the audio stream represented by the playlist and passing it through a signal processing pathway. At any point in time, a track has a single playlist associated with it. When the track is used to record, that playlist will have one or more new regions added to it. When the track is used for playback, the contents of the playlist will be heard. You can change the playlist associated with a track at (almost) any time, and even share playlists between tracks.</p>
-<p>If you have some experience of other <abbr title="Digital Audio Workstations">DAWs</abbr>, then you might have come across the term "virtual track", normally defined as a track that isn't actually playing or doing anything, but can be mapped/assigned to a "real track". This concept is functionally identical to Ardour's playlists. We just like to be little more clear about what is actually happening rather than mixing old and new terminology ("virtual" and "track") into confusing terminology.</p>
