(2) To record each part separately:
You can also record the parts of your performance
independently; for example, first recording the chords and
bass to the song (using the Lower and Pedalboard), and
after that recording the melody. This function also lets you
record keyboard percussion and performance control data,
such as registration changes and expression pedal operation,
separately from the other parts of the song.

Set up the M.D.R. for recording, as you did in the
section above.
The first steps in recording parts separately are the
same as for normal recording on page 71:
1. Memorize all the registrations needed for your
performance to the Registration Memory
numbered buttons, and set the registration that
will be used at the beginning of the song.
2. Insert a formatted disk.
3. Select the song number to which you will record
your performance.
4. Press the RECORD button to make the Music
Disk Recorder ready to record.

Select the parts for recording.
Pressing the RECORD in the procedure 1.-4) above
turns on the all parts' LEDs in the upper left row
indicating that each part is ready to record.
Press the RECORD buttons for each part in the upper
left row to turn off the parts you don't want to record.
For this example, press RECORD/UPPER. The
PLAY/UPPER lamp in the upper right row lights
up.
RECORD/UPPER - Records the performance
data of the Upper keyboard when turned on.
RECORD/LOWER - Records the performance
data of the Lower keyboard when turned on.
RECORD/PEDAL - Records the performance
data of the Pedalboard when turned on.
RECORD/CONTROL - Records the Control
data (see Outline of M.D.R. Operation above) when
turned on.
The LED lamps above the buttons indicate the record
status of the parts.
This example operation disables recording of the
Upper part.
