You can use Song Memory to record your lesson play (lesson
recording) and to record your keyboard play along with the
Auto Accompaniment you are using (performance recording).
Parts and Tracks
How data is recorded to Song Memory and the type of data
that is recorded depends on whether you are performing a
performance recording operation or a lesson recording
operation.
Lesson Recording
With lesson recording, you use the LEFT/TRACK1 button
and the RIGHT/TRACK 2 button to select recording of only
the left-hand part, only the right-hand part, or both the left-
hand and right-hand parts.
Performance Recording
With performance recording, Song Memory operates like a
tape recorder or sequencer. In this case, you can use the LEFT/
TRACK1 button and the RIGHT/TRACK 2 button to select
the Song Memory track you want to record to.
Performance recording records the data shown in the
illustration below, using two memory tracks.
•Since each track is independent of the other, you can edit a
recording by re-recording only one of the tracks.

Using the SONG MEMORY Button
When performing a performance recording or lesson
recording, you will need to use the SONG MEMORY button
to select recording or playback. Each press of the SONG
MEMORY button cycles through the song memory options
in the sequence shown below.
Song Memory Capacity
Song Memory can hold a total of approximately 13,000 notes,
which can be divided between a lesson recording and a
performance recording. Note that you can use up all 13,000
notes for either the lesson recording or the performance
recording. If you do, you will not be able to record anything
for the other type of recording.
•When the number of remaining notes becomes less than
about 100 while you are recording, the SONG MEMORY
indicator and the track/part indicator (L, R) will start to
flash at high speed.
•Recording will stop automatically if Song Memory becomes
full.
If you are using Auto Accompaniment or a rhythm, they will
also stop playing at this time.
IMPORTANT!
•Never turn off the keyboard while it is recording or
standing by for recording to Song Memory. Doing so will
cause all of the song data currently stored in the Song
Bank user area to be deleted.

Recorded Data Storage
•Anything previously stored in song memory is replaced
whenever you make a new recording.
•Song Memory contents are retained even when power is
turned off, as long as the keyboard is being supplied battery
or AC adaptor power. If you remove the batteries or should
the batteries go dead while the keyboard is not being
supplied power by the AC adaptor, song memory contents
will be deleted. Be sure to supply power to the keyboard
with the AC adaptor when replacing batteries.
•Turning off the keyboard while a record operation is in
progress causes the contents of the track you are currently
recording to be lost.
Recording Play Along with a Built-

This section describes how to use layer (to play two tones
with a single key) and split (to assign different tones to either
end of the keyboard), and how to make touch response,
transpose, and tuning settings.
Using Layer
Layer lets you assign two different tones (a main tone and a
layered tone) to the keyboard, both of which play whenever
you press a key. For example, you could layer the FRENCH
HORN tone on the BRASS tone to produce a rich and brassy
sound.
To layer tones
1First select the main tone.
Example:To select “078 BRASS” as the main tone, press
the TONE button and then use the number
buttons or [+] and [–] buttons to input 0, 7 and
then 8.
2Press the LAYER button.

3Select the layered tone.
Example:To select “077 FRENCH HORN” as the layered
tone, use the number buttons or [+] and [–]
buttons to input 0, 7 and then 7.
4Now try playing something on the keyboard.
•Both tones are played at the same time.
5Press the LAYER button again to unlayer the tones
and return the keyboard to normal.

Using Split
With split you can assign two different tones (a main tone
and a split tone) to either end of the keyboard, which lets
you play one tone with your left hand and another tone with
your right hand. For example, you could select STRINGS as
the main (high range) tone and PIZZICATO STRINGS as the
split (low range) tone, putting an entire string ensemble at
your fingertips.
Split also lets you specify the split point, which is the location
on the keyboard where the changeover between the two tones
occurs.
To split the keyboard
1First select the main tone.
Example:To select “062 STRINGS” as the main tone,
press the TONE button and then use the
number buttons or [+] and [–] buttons to input
0, 6 and then 2.
2Press the SPLIT button.
3Select the split tone.
Example:To select “060 PIZZICATO STRINGS” as the
split tone, use the number buttons or [+] and
[–] buttons to input 0, 6 and then 0.
4Specify the split point. While holding down the
SPLIT button, press the keyboard where you want
the leftmost key of the high end range to be.
Example:To specify G3 as the split point, press the G3
key.

Transposing the Keyboard
Transpose lets you raise and lower the overall key of the
keyboard in semitone units. If you want to play an
accompaniment for a vocalist who sings in a key that’s
different from the keyboard, for example, simply use
transpose to change the key of the keyboard.
To transpose the keyboard
1Press the RHYTHM button to enter the Rhythm
Mode.
•Note that you cannot transpose the keyboard while
in the Song Bank Mode or Piano Bank Mode.

Using Layer and Split Together
You can use layer and split together to created a layered split
keyboard. It makes no difference whether you layer tones
first and then split the keyboard, or split the keyboard and
then layer tones. When you use layer and split in combination,
the high range of the keyboard is assigned two tones (main
tone + layered tone), and the low range two tones (split tone
+ layered split tone).
To split the keyboard and then layer
tones
1Press the TONE button and then input the tone
number of the main tone.
2Press the SPLIT button and then input the number
of the split tone.
•After specifying the split tone, press the SPLIT button
to unsplit the keyboard.
3Press the LAYER button and then input the number
of the layered tone.
•Note that you can reverse steps 2 and 3, specifying
the layered tone first and then the split tone.

NOTE
•The keyboard can be transposed within a range of –12
(one octave downwards) to +12 (one octave upwards).
•The default transpose setting is “00” when keyboard
power is turned on.
•If you leave the transpose screen on the display for about
five seconds without doing anything, the screen is
automatically cleared.
•The transpose setting also affects playback from memory
and Auto Accompaniment.
•To return the keyboard to its default key, perform the
above procedure and press both of the KEY CONTROL/
TRANSPOSE buttons ( 
 and  ) at the same time in
step 2. You could also use the [+] and [–] buttons to
change the transpose setting to “00”.
•The effect of a transpose operation depends on the pitch
of each note and on the tone you are currently using. If
a transpose operation causes a note to be outside of
the allowable range for a tone, the same note in the
nearest octave within the range will be substituted.
Using Touch Response
When touch response is turned on, the relative volume of
sound output by the keyboard is varied in accordance with
the amount of pressure applied, just like an acoustic piano.
Touch response provides a choice of three settings, described
below.
OFF:This setting turns off touch response. Keyboard pressure
does not have any affect on the output notes.
1:This setting provides touch response that is suited for
normal play.
2:This setting increases touch response, so stronger keyboard
pressure has a greater effect than the “1” setting.
1Press the FUNCTION button until the TOUCH
RESPONSE SELECT screen appears.
2Use the [+] and [–] or [0] and [1] buttons to change
the setting.
Example: To select touch response 2.
•Touch response is on when TOUCH RESPONSE
indicator is on.
•Touch response is off when TOUCH RESPONSE
indicator is off.
NOTE
•Touch response not only affects the keyboard’s internal
sound source, it also is output as sending message.
•Song memory playback and accompaniment do not
affect the touch response setting.
About FUNCTION button
Each press of the FUNCTION button cycles through a total
of 10 setting screens. If you accidentally pass the screen you
want to use, keep pressing the FUNCTION button until the
screen appears again.
