IMPORTANT SAFETY PRECAUTIONS
TASCAM DP-02/DP-02CF
1 – Starting out with your DP-02/DP-02CF
Because a song is not just the parts you hear, but possibly
unused audio parts (see “About track editing” on page 47),
there may be operation history such as cut out, copy or etc.
that you want to delete so you don’t waste hard disk or a
CF card space.
CAUTION
This operation cannot be undone. Only do it if you are
sure you do not want the unused parts.
You can delete the unused data and all the operational
histories from the currently-loaded song.
1. Press and hold the
SHIFT
key and press the
CLEAR
key. This action brings up the
HISTORY
screen as
below:
2. Press
YES/ENTER
to delete the unused data and the
operation history, or
NO/EXIT
to cancel the opera-
tion.
When
YES/ENTER
is pressed, the unit confirms
again if you are sure.
3. Press
YES/ENTER
to delete.
Deleting unused data
Undoing many actions at once (multi-undo) or redoing
many actions at once (multi-redo) is possible using the
HISTORY
key.
1. Press
HISTORY
. The history list appears:
An asterisk (*) is shown to the right of the current
action.
When you undo an action (or event), you undo the
action highlighted, and all actions before it.
When you redo an action (or event), you redo the
action highlighted, and all actions after it.
NOTE
Event numbering starts at
-START UP- 0
at the
bottom of the history list (you can’t change this list).
The top line on the list is the most recent event.
2. Use the
DATA
dial to scroll up and down through the
list until you come to the action you want to undo
or redo (together with all the actions that have been
performed since then).
3. Press
YES/ENTER
to do the multi-undo or multi-
redo.
The screen goes back to the home screen, and the
status of the unit changes to the status that it had
immediately after or before the highlighted opera-
tion in the list was performed.
The
HISTORY
key lights up.
To cancel the
HISTORY
function, select the most
recent event (the action on the top of the list) and
press
YES/ENTER
. The screen goes back to the
home screen and the
HISTORY
key becomes unlit.
After performing a multi-undo, and when a new menu
action is performed (copy, cut or etc.), all the redoable
actions are deleted and the new action becomes the most
recent action on the undo history list.
When the
HISTORY
key is lit, and when undo is performed
using the
UNDO/REDO
key, the
UNDO/REDO
key
also lights up. When two keys are lit, and when redo is
performed, the
UNDO/REDO
key becomes unlit. The
HISTORY
key stays lit.
NOTE
You cannot use the UNDO/REDO key when the UNDO
HISTORY screen is showing.
CAUTION
Of your operational history (actions), only the 500
most recent operations are stored when you shut
down the unit. Any history operation older than the
500th one is forgotten.
