EDIT LAYERS
Edit Layers (Figure 44-1 on page 504) allow you to
edit, select, audition and otherwise manipulate
waveform data, soundbites, stretch edits, sampler
loops, volume data, beats and tempo maps in the
audio file. Features specific to each edit layer are
explained in detail later in this chapter.
A handy shortcut
Press Command/Ctrl-return to cycle through the
edit layers.
TRANSPORT LOCK
The Transpor t Lo ck button in the Waveform Editor
(Figure 44-1 on page 504) locks playback of the
audio file displayed in the Waveform Editor
window to Digital Performer’s main transport
controls. You can play, stop, rewind and otherwise
control playback of the audio file displayed in the
Waveform Editor using all of the familiar transport
features in the Control Panel. In essence, the
Waveform Editor acts like the currently enabled
sequence (with regard to all transport-related
features).
When you unlock the Transport Lock button,
transport control returns to the currently play-
enabled sequence.
Control Panel
When the Transport Lock button is engaged, all of
the features in Digital Performer’s main transport
control panel, such as Memory Cycle, can be
employed for Waveform Editor playback. In
addition, all of Digital Performer’s other playback-
related features apply to the Waveform Editor. This
includes:
■ “Auto scroll” on page 216
■ “Displaying the playback wiper” on page 217
■ “Click Preferences” on page 246
■ “Memory buttons” on page 196
■ “Displaying the playback wiper” on page 217
■ “Zooming with the wiper” on page 218
SELECTION
All of the features in the Selection Information
window (“Selection Information” on page 343) can
be applied to selection procedures in the Waveform
Editor, including pre-roll, post roll and so on.
Additionally, you can click a channel label (to the
left of the vertical amplitude ruler) to apply the
current selection to only that channel.
GLOBAL TIME FORMAT
The global time format controls how time is
displayed in the Waveform Editor. See “Time
Formats window” on page 90. For example, if you
wish to specify a selection by entering the start
time and end time in samples, you can set the
global time format to samples and then use the
Selection Information window to type in the
selection.
UNDO HISTORY
Each audio file has its own Undo History. To open
its Undo History window, choose Edit menu >
Undo History while the audio file is being displayed
in the Waveform Editor and the Waveform Editor
has the window focus. The audio file undo history
allows you to take back changes you’ve made to the
audio file. You can even remove individual
destructive edits in the undo history, without
affecting other items in the history. For complete
details, see “Undo History for audio files” on
page 556.
THE AUDIO FILE OVERVIEW
As shown in Figure 44-1 on page 504, the narrow
strip above the main waveform display provides an
overview of the entire audio file.
