Inserting Silence
The Insert Silence command is a simple and con-
venient way to insert silence on audio, MIDI,
and Instrument tracks. This command lets you
make a selection on a track (or tracks) and insert
precisely that amount of silence.
In Shuffle mode, all data on the track is shuffled
later in the track by an amount equal to the se-
lection.
In Grid mode, the Insert Silence command
works just like the Clear command.
Shuffle Mode When inserting silence on multi-
ple tracks in Shuffle mode, the following condi-
tions apply:
‹ If any track is displayed as audio or MIDI data,
the selected duration of silence is inserted into
the audio or MIDI data and all underlying auto-
mation data on all selected tracks. All subse-
quent regions are shuffled by the amount of
silence inserted. On MIDI tracks, only notes that
are selected from the beginning are affected, so
if you have selected the tail of a note and you In-
sert Silence, the note will remain unchanged.
‹ If all selected tracks are displayed as automa-
tion data, the selected range is cleared of auto-
mation data only of the type visible on each
track. Regions are not shuffled. Instead, a blank
gap appears equal to the length of the selection.
‹ If all selected tracks are displayed as automa-
tion data, press the Start key (Windows) or Con-
trol (Mac) while choosing the Insert Silence
command to inserts silence on all automation
playlists for all selected tracks. Regions are not
shuffled.
The Insert Silence command also affects
markers in any selected Conductor Rulers
(such as the Tempo or Meter rulers).
