STEP 2

The 3-step lesson feature takes you through the three distinct
steps described below to help you learn to play tunes on the
keyboard.

J Step 1 – Master the timing.
In this step, pressing any key on the keyboard plays the
correct note, so you can concentrate on getting the timing
right without worrying about playing the right note. The submelody (obbligato) waits until you press a key before
proceeding to the next phrase.

J Step 2 – Master the melody.
In this step, you use the display to learn which fingers you
should use and how loud or soft to play, and the key light
system to learn which keyboard keys to press. The submelody (obbligato) waits until your play the correct note, so
you can learn at your own pace.

LEFT/TRACK 1
STEP 3

tunes for a 3-step lesson, you can practice playing along with
the melody (right hand) part only.

J Two-hand Tunes (Numbers 70 through 99)
These types of tunes are played with both hands, as in a piano
solo. When using these tunes for a 3-step lesson, you can
practice playing along with both the left hand and right hand
parts.

Key Lighting System Operation and Display
Contents During 3-step Lesson Play
Whenever you select an Auto Accompaniment tune (00 to 69)
for 3-step lesson play, the key lighting system shows you
which keys to press, while the display shows you the notes
and their fingerings.

J Step 3 – Play at normal speed.
This is where you enjoy actually playing the tunes you learn
using Step 1 and Step 2. The key light system still shows you
which keyboard keys to press, but accompaniment proceeds
at normal speed regardless of whether or not you play the
correct notes.

J Note Pitch
The keyboard key that should be pressed lights, while the
actual pitch of the note appears in the display’s staff notation
area. The fingers you should use to play the notes are also
shown on the display.

J Note Length

Tune Types and Their Parts
There are two types of tunes in the Song Bank: Auto
Accompaniment tunes and two-hand accompaniment tunes.
The parts available for 3-step lesson practice depend on the
type of tune you are using.

J Auto Accompaniment Tunes (Numbers 00 through
69)

Keyboard keys stay lit for as long as the note should be
played. The staff notation and fingerings also remain on the
display for the length of the note.

J Next Note
The keyboard key for the next note to be played flashes, while
a number appears on the display near the finger you should
use to play the next note.

As their name suggests, these tunes are made up of an Auto
Accompaniment part and a melody part. When using these

Note length is not indicated when you are using two-hand
tunes (70 to 99) with 3-step lesson Steps 1 and 2. As soon
as you press a lit key, it goes out and the next key to be
played starts to flash.
Note length is indicated by the key light system when you
use a two-hand tune with Step 3. In this case, the next key
to be pressed does not flash when you press a lit key and
the next finger number does not appear on the display.
Only the current finger number is shown.

Accompaniment (left-hand part) waits until you
press any key to play a note.

Use the procedure under “Adjusting the Tempo” on page
E-22 to adjust the tempo for 3-step lesson play.

If you accidentally press more than one key in
succession, accompaniment is played for the
corresponding number of notes.

Step 1 – Master the timing.

Pressing more than one key at the same time
counts as a single melody note. Pressing a key
while another key is held down is counted as two
melody notes.

Select the Song Bank tune you want to use.
Press the STEP 1 button to start Step 1 play.
After a count sounds, the keyboard stands by and
waits for you to play the first note of the tune.

Press any keyboard keys to play the melody
(right hand part).

The key for the next note to be played flashes
while the keyboard waits for you to play it. When
you press any key to play the note, the key
remains lit as the note plays.

Song Memory Button Operation
Each press of the SONG MEMORY button cycles through the
functions shown below.

Tracks
The song memory of this keyboard records and plays back
notes much like a standard tape recorder. There are two
tracks, each of which can be recorded separately. Besides
notes, each track can be assigned its own tone number.
During playback you can adjust the tempo to change the
speed of playback.

Selecting a Track
Press the LEFT/TRACK 1 button to select Track 1 and the
RIGHT/TRACK 2 button to select Track 2. The letter “L” (left)
appears on the display to indicate Track 1 is selected, and the
letter “R” (right) appears to indicate Track 2 is selected.

J Playback
Track 1 is the basic track, which can be used to record Auto
Accompaniment along with the melody. Track 2 can be
used for melody only, and is for adding to what is recorded
in Track 1.
Note that each track is independent of the other. This
means that if you make a mistake while recording, you
need to re-record only the track where the mistake was
made.

E-36

Each press of the LEFT/TRACK 1 and RIGHT/TRACK 2
button while the keyboard is in playback standby (see “Song
Memory Button Operation” above) toggles playback of the
corresponding track on and off. The letter that identifies a
track (L or R) appears on the display whenever playback of
that track is turned on.

Memory Data Storage
Anything previously stored in memory is replaced
whenever you make a new recording.
Memory contents are retained as long as the keyboard is
supplied with electrical power. Unplugging the AC
adaptor when batteries are not loaded or when loaded
batteries are dead cuts off the keyboard’s electrical power
supply, causing all data stored in memory to be deleted.
Be sure to plug the keyboard into an electrical outlet with
the AC adaptor before 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.

Track 1 Real-time Recording Variations
The following describes a number of different variations you
can use when recording to Track 1 using real-time recording.
All of these variations are based upon the procedure
described under “To record to Track 1 using real-time

The length of the ending depends on the rhythm you are
using. Check the length of the pattern you are using and set
the length of the chord accordingly in step 7. Making the
chord too short in step 7 can result in the ending pattern
being cut off.

J To step record chords without rhythm
After performing steps 1 through 4, you can use the number
buttons to input the length of the specified chord. Skipping
step 5 (not pressing the SYNCHRO/ENDING button) creates
chord without rhythm, so you can input a rest by pressing the
[0] button in step 6 and then specifying the length of the rest
in step 7.

J To add chord accompaniment part way through

Editing Data While Step
Recording
Memory data can be thought of as a musical score that
progresses from left to right, with the input point normally at
the far right of the recorded data. The following procedure
describes how to move the input point to the left in order to
make changes in data you have already input. Note, however,
that moving the input point to the left and changing data
automatically deletes all of the data to the right of the input
point.

If you move from an area that contains note data
to an area that does not contain note data, each
press of FF moves the input point to the next beat.
Pressing the REW button, however, causes the
input point to jump back to the location of the
first note or rest to the left.

To edit data while step recording

While a step recording operation is in progress,
use the FF and REW button to move the input
point to the location where you want to edit the
data you have already input.
If notes are already recorded, each press of FF or
REW moves the input point to the next successive
note. The data recorded at the current input point
appears on the display.

Press the [+] and [–] buttons.

Press the [+] button to start the data editing
operation or [–] to clear the data editing screen
without changing anything.
Pressing the [+] button automatically clears all
data to the right of the current input point. Next,
the keyboard stands by for input of step
recording data.
Pressing the [–] button clears the data editing
screen and returns to the step recording screen
where you can move the input point.

If notes are not recorded, each press of FF or REW
moves the input point to the next successive beat.

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.

Select the layered tone.
Example:
To select “060 FRENCH HORN” as the layered
tone, use the number buttons or the [+] and [–]
buttons to input 0, 6 and then 0.

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.

Now try playing something on the keyboard.

To layer tones

First select the main tone.
Example:
To select “061 BRASS” as the main tone, press
the TONE button and then use the number
buttons or the [+] and [–] buttons to input 0, 6
and then 1.

Press 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 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

To select “048 STRINGS 1” as the main tone,
press the TONE button and then use the number
buttons or the [+] and [–] buttons to input 0, 4
and then 8.

To specify G3 as the split point, press the G3 key.

Now try playing something on the keyboard.
Every key from F#3 and below is assigned the
PIZZICATO tone, while every key from G3 and
above is assigned the STRINGS tone.

Press the SPLIT button again to unsplit the
keyboard and return it to normal.

SPLIT

Press the SPLIT button.

Specify 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:

First select the main tone.
Example:

Lit

Select the split tone.
Example:
To select “045 PIZZICATO STR” as the split
tone, use the number buttons or the [+] and [–]
buttons to input 0, 4 and then 5.

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).

Press the TONE button and then input the tone
number of the main tone.

Lit

Specify the split point.
While holding down the SPLIT button, press the
keyboard where you want the leftmost key of the
low end range to be.

To split the keyboard and then layer tones

Input the number of the layered split tone.

Play something on the keyboard.
Press the LAYER button to unlayer the keyboard,
and the SPLIT button to unsplit it.

LAYER SPLIT

Press the SPLIT button and then input the
number of the split tone.

Lit

After specifying the split tone, press the SPLIT
button to unsplit the keyboard.

Press 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.

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.

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 turn touch response on and off

Press the TOUCH RESPONSE button to toggle
touch response on and off.
Touch response is on when touch response
indicator is on.

To transpose the keyboard

Press the TRANSPOSE/TUNE/MIDI button
until the transpose screen appears on the
display.

Use the [+], [–], and the number buttons to
change the transpose setting of the keyboard.
Example:

Lit

To transpose the keyboard five semitones
upwards.

Touch response is off when touch response
indicator is off.

You can adjust touch response sensitivity using the
procedure under “TOUCH CURVE (Default: 0)” on page
E-55.
Touch response not only affects the keyboard’s internal
sound source, it also is output as MIDI data.
Memory playback, accompaniment, and external MIDI note
data does not affect the touch response setting.

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 song
memory and Auto Accompaniment.

TRANSPOSE/TUNE/MIDI Button
Each press of the TRANSPOSE/TUNE/MIDI button cycles
through a total of 12 setting screens: the transpose screen, the
tuning screen, and 10 MIDI setting screens (page E-52). If you
accidentally pass the screen you want to use, keep pressing
the TRANSPOSE/TUNE/MIDI button until the screen
appears again.

The keyboard can be tuned within a range of –50 cents to
+50 cents.
* 100 cents is equivalent to one semitone.
The default tuning setting is “00” when keyboard power is
turned on.
If you leave the tuning screen on the display for about five
seconds without doing anything, the screen is
automatically cleared.
The tuning setting also affects playback from song memory
and Auto Accompaniment.
