3 It is very useful to be able to tag different locations in a session for
4 later use when editing and mixing. Ardour supports both
5 <dfn>locations</dfn>, which define specific positions in time,
6 and <dfn>ranges</dfn> which define a start and end position in time.
9 In addition to the standard location markers, there are several more kinds of
14 <dfn>BBT markers</dfn> make it possible to restart the count of bars and
15 beats multiple times in a session.
18 <dfn>Time signature markers</dfn> allow changing the time signature from
19 e.g. 4/4 to 6/8 and then to 3/4 within the same composition.
22 <dfn>Tempo markers</dfn> allow changing tempo within the same composition
23 either abruptly or gradually.
26 <dfn>Range markers</dfn> helps preserving selections (ranges) by storing

30 The <dfn>loop range</dfn> defines the start and end points for Looping.
33 The <dfn>punch range</dfn> defines the in and out points for punch
37 <dfn>CD markers</dfn> are locations that are restricted to legal
38 <dfn>CD sector boundaries</dfn>. They can be used to add track index
39 markers to compact disc images.
42 <dfn>Cue markers</dfn> allow integrating elements of non-linear grid-based
43 workflow into the linear timeline-based workflow by launching and stopping
44 user-defined cues at particular points in time.
