System information
Item Description
Enable looping on 
events by default
When this check box is selected, the Loop event switch will be 
enabled for new events.
When this switch is enabled, events will repeat if you drag the end of 
an event past the end of the media file.
Preserve pitch when 
stretching audio events
When this check box is selected, the pitch of  an audio event is 
preserved when you hold Ctrl and drag the end of the  event to 
change its duration. When the check box is cleared, audio events'  
pitch will increase when you make an event shorter and will decrease 
when  you make an event longer.
If you change this setting during an editing  session, the new 
setting will affect only media that you add to the timeline  after 
changing the setting. To change the behavior for existing events
  on the timeline, use the Time stretch  / pitch shift controls on 
the Audio Event tab of the Event Properties dialog.
For more information, see "Editing Event Properties" on page 180 and 
"Adjusting an Event's Length" on page 158.
Cut, copy, and delete 
grouped events
When this check box is selected, cutting, copying, or deleting an 
event will affect all events in the same group.
For more information, see "Cutting, copying, and pasting events" on 
page 142 and "Grouping Events" on page 173.
Do not quantize to 
frames for audio-only 
edits
When this check box is selected, edits to audio events (such as event 
moves, trims, and ASR times) are not quantized to frame boundaries 
even if Quantize to Frames is enabled.
For more information, see "Moving events" on page 137, "Adjusting 
an Event's Length" on page 158, "Event Envelopes" on page 166, and 
"Quantize to Frames" on page 142.
Collapse loop region 
when no time selection 
is present
When this  check box is selected, the loop region is reset when no data 
is selected.  If the check box is cleared, the loop region will retain the 
last selection.
JKL/shuttle speed Choose a setting  from the drop-down list to set the speed that will be 
used for scrubbing  the timeline with the JKL keys or with a 
multimedia  controller.
For more information, see "Scrubbing" on page 33 and "Using a
