Markers appear in the Markers ruler with a thin
yellow line extending down through all tracks
in the Edit window (to assist in arranging and
aligning track material). You can click a Marker
in the Markers ruler to recall its location along
with its stored General Properties.
Markers in the Markers ruler
Selection Recalls an Edit selection or edit cursor
location whose reference can be either Bar|Beat
(tick-based) or Absolute (sample-based). A Selec-
tion Memory Location lets you store Edit selec-
tions, for one or more tracks, that you return to
often within a session. If the Timeline and Edit
Selections are linked, a Selection Memory Loca-
tion can recall record and play ranges.
Only contiguous selections can be saved
with Memory Locations. Discontiguous se-
lections, made with the Object Grabber tool,
will be recalled as if the selections were
made with the Time Grabber tool.
None Recalls no Time Properties and is therefore
referred to as a General Properties Memory Loca-
tion.
Bar|Beat and Absolute Reference
The Reference pop-up determines whether the
Marker or Selection Memory Location is
Bar|Beat or Absolute. When set to Bar|Beat, the
Memory Location is tick-based and its bar and
beat location remains constant if the tempo is
changed—though its relation to audio is scaled,
resulting in a new sample location.
When set to Absolute, the Memory Location is
sample-based and its bar and beat location shifts
if the tempo is changed—though its sample lo-
cation remains constant, along with its relation
to audio material.
Bar|Beat Marker (left) and Absolute Marker (right)
In the Markers ruler, Markers that are Bar|Beat
appear as yellow chevrons, and Markers that are
Absolute appear as yellow diamonds.
General Properties
All three types of Memory Locations (Marker,
Selection, and None) can store and recall any
combination of the following General Proper-
ties:
Zoom Settings Recalls the horizontal, audio,
and MIDI zoom values for audio, MIDI, and In-
strument tracks.
Pre- and Post-Roll Times Recalls pre- and post-
roll times (but not whether they are enabled).
This property can be stored with a Selection
Memory Location to recall record and play
ranges along with pre- and post-roll.
Track Show/Hide Recalls which tracks are hid-
den. Use this property to display groups of
tracks for editing and mixing.
Track Heights Recalls all Track Heights. Use this
option along with Zoom Settings to recall edit
environments that are suited for particular
tasks, such as editing down to the sample level
or trimming MIDI notes.
Group Enables Recalls which Edit and Mix
Groups are enabled. This option is helpful in re-
calling groups for particular edit and mixing op-
erations, such as muting all drum tracks or fad-
ing a stereo pair.
