10 In Ardour, "editing" describes the process of
16 making modifications to playlists. Recall that
17 <glossterm linkend="gt-playlist">playlists</glossterm> are nothing

39 By default, when you move objects around, they move freely. There
40 <emphasis>is</emphasis> a "granularity" to the motion, but it is a
41 single audio frame (so typically on the order of 1/48000'th or
42 1/96000'th of a second), and at most zoom levels it will not be
47 However, this is not always the way you want to move some kinds of
48 objects. If you are working with structured compositions that utilize
49 traditional concepts of bars, beats, rythmn and so forth, you will
50 often want to move regions so that that they always align to specific
51 periodic time points that correspond to the start of a bar, or a beat
52 etc. If you are working on a movie soundtrack, you may prefer to have
53 regions always align to SMPTE frames, or perhaps even to whole
58 Ardour provides a wide variety of "snap" settings. If any but "None"
59 is selected, they define a grid of timepoints which will be used to
60 "snap" object positions as they are dragged. The grid can be regular
61 (as is the case if you choose "Beats", for example), or it can be
62 completely irregular (if you choose "Marks", for example). It can even
63 consist of a <emphasis>single</emphasis> timepoint (if you choose
64 "Edit cursor", for example).

261 Move the mouse pointer to the toolbar panel of the editor window.
262 Click on the "expansion arrow" of the "Snap setting" chooser. This
263 will popup a list of available snap settings. If necessary, scroll
264 down to see your desired choice. Click on your choice in the list to
265 dismiss it and make Ardour switch to the new setting.
270 Changing snap settings has <emphasis>no</emphasis> effect on the
271 position of any existing region. Its effect is only on objects
277 The snap setting also affects moving the playhead, the edit
278 cursor, loop/punch and location markers, and dragging/moving range
284 <section id="snap-mode">
285 <title> Snap Mode </title>
287 There are two subtly different ways in which the snap setting can
288 affect region motion:
294 <term>normal snap mode</term>
297 regions can only be moved to positions defined by the snap
298 setting. It is not possible to move them to intermediate
305 <term>magnetic snap mode</term>
308 regions can still be moved to positions not defined by the
309 setting, but they "stick" to the timepoints that are when
310 dragged across them. Imagine that the timepoints and the
311 regions are magnetic - or just try it and see.
318 However, you can press the <emphasis>snap modifier</emphasis> key
319 while dragging, and the snap setting will be ignored. By default,
320 this is the key on your keyboard that generates
321 <emphasis>Mod3</emphasis> , but you can modify this from the
322 <emphasis>Options Editor</emphasis> keyboard tab.
