Optimizing a song
By using the top panel [UNDO] key and [REDO] key, you can cancel or re-exe-
cute the last-performed recording or track editing operation. By repeatedly press-
ing the [UNDO] key, you can retrace as many as 15 previous operations. Undo/
redo can be a very convenient function, but when you record or perform a track
editing operation, data for the corresponding number of Undo operations must
be maintained, and this data will occupy space on the hard disk.
The “Optimize” command deletes any audio data that is not currently being used
by the song; i.e., it deletes the Undo data. In order to recover this space, we rec-
ommend that you execute the Song Optimize command when you are finished
recording and editing.
1. Press the [SONG] key → [F3] key.
The SONG screen Song Edit page will appear in the display. The upper part of the
display will show a list of the songs currently saved on the hard disk.
2. Move the cursor to the list in the upper part of the display, use the
[DATA/JOG] dial to select the song that you wish to optimize, and press
the [ENTER] key.
An “E” symbol will appear in the left edge of the list, and the corresponding song
will be selected optimization.
It is not possible to execute Optimize with more than one song selected. If Opti-
mize is executed when the “E” symbol is displayed for more than one song, an
error message will be displayed.
3. Move the cursor to the OPTIMIZE button, and press the [ENTER] key.
A popup window will ask you to confirm the Optimize command.
4. To execute the Optimize command, move the cursor to the OK button
and press the [ENTER] key.
The current song will be saved automatically, and then the Optimize command
will be executed.
