How the Three Step Lesson System operates in Steps 1 through 3
When using an auto-accompaniment Song Bank tune with the Three Step Lesson
System, the lights indicate not only the note you should play, but how long you
should play it (how long you should keep the key depressed). The following de-
scribes what illumination of keys indicates.
•Note Guide: A lit key indicates the note to be played.
•Length Guide: Key remains lit for as long as note should be played.
•Next Note Guide: A flashing key indicates the next note to be played.
•Consecutive Note Guide: When a key lights, goes out momentarily, and then lights
again, it indicates that the same note should be played in succession.

1 to 3).
•When the power on alert function operates (page E-16).
Number of Simultaneously Lit Keys
Up to four keyboard keys can be lit at the same time.
To change the tone used for the melody of a Song Bank tune
1. Following step 3 of the procedure on page E-29, press the TONE button.
•Both the SONG BANK icon and TONE icon light,
along with the tone number of the tone that is cur-

Step 1: Easy Play
You can press the ONE KEY PLAY buttons or any of the keyboard keys to play along
with the melody (right hand part) of the Song Bank tune. You do not have to worry
about pressing the right key, so you can concentrate on getting the timing right.
1. Press the STEP 1 button.
•When you do, the STEP 1 icon lights.
•After a count sounds, the keyboard stands by and waits
for you to play the first note of the tune. If the tune in-
cludes intro measures, the keyboard enters standby after
the intro measures are complete.
2. Press the ONE KEY PLAY buttons to play each note of the tune.
•The accompaniment (left hand) part of the tune follows along as you
play the melody (right hand) part.
•The keyboard key that corresponds to the next note to be played
flashes, and lights when you play the note.
•The rhythm (percussion) part does not sound.
3. Try pressing any one of the keyboard keys in place of the ONE KEY PLAY buttons.
•Pressing any keyboard key plays the correct melody (right hand part) note.
•Pressing more than one (up to four) keyboard keys plays the corresponding number
of melody notes.
The correct note is played even if you do
not press the key that is lit.
4. To interrupt an Easy Play session, press the START/STOP button.
•When you do, the STEP 1 icon goes out.
Step 2: Slow Play
With Slow Play, you have to play the note that the Three Step Lesson System
indicates. But don’t worry - the accompaniment (left hand part) waits until you can
play the correct note before continuing. This means you can take your time and play
at your own pace.
1. Press the STEP 2 button.
•When you do, the STEP 2 icon lights.
•After a count sounds, the keyboard stands by and waits
for you to play the first note of the tune. If the tune in-
cludes intro measures, the keyboard enters standby after
the intro measures are complete.

To check if the right hand or left hand part is currently selected
(two-hand tunes only)
The Three Step Lesson System tells you what part is selected whenever you press the

MIDI
478B-E-038A
What is MIDI?
The letters MIDI stand for Musical Instrument Digital Interface, which is the name of
a worldwide standard for digital signals and connectors that makes it possible to
exchange musical data between musical instruments and computers (machines) pro-
duced by different manufacturers. MIDI compatible equipment can exchange key-
board key press, key release, tone change, and other data as messages.
Though you do not need any special knowledge about MIDI to use this keyboard as a
stand-alone unit, MIDI operations require a bit of specialized knowledge. This sec-
tion provides you with an overview of MIDI that will help to get you going.
MIDI Connections
MIDI messages are send out through the MIDI OUT terminal of one machine to the
MIDI IN terminal of another machine over a MIDI cable. To send a message from this
keyboard to another machine, for example, you must use a MIDI cable to connect the
MIDI OUT terminal of this keyboard to the MIDI IN terminal of the other machine.
To send MIDI messages back to this keyboard, you need to use a MIDI cable to
connect the other machine’s MIDI OUT terminal to the MIDI IN terminal of this
keyboard.
To use a computer or other MIDI device to record and playback the MIDI data
produced by this keyboard, you must connect the MIDI IN and MIDI OUT terminals
of both machines in order send and receive data.
MIDI IN MIDI OUTMIDI IN MIDI OUT
Computer etc. 
						

							E-37478B-E-039A
MIDI Channels
MIDI allows you to send the data for multiple parts at the same time, with each part
being sent over a separate MIDI channel. There are 16 MIDI channels, numbered 1
through 16, and MIDI channel data is always included whenever you exchange data
(key press etc.)
Both the sending machine and the receiving machine must be set to the same channel
for the receiving unit to correctly receive and play data. If the receiving machine is set
to Channel 2, for example, it receives only MIDI Channel 2 data, and all other
channels are ignored.
With this keyboard, messages received over MIDI Channels 1, 2, 3, 4, and 10 can be
used for multi-timbre play of up to five different instrument parts. The tone and
volume settings for these five channels must be controlled by messages sent from an
external device.
Conversely, keyboard operations are sent to external devices over MIDI Channel 1.
General MIDI
General MIDI standardizes MIDI data for all sound source types, regardless of
manufacturer. General MIDI specifies such factors as tone numbering, drum sounds,
and available MIDI channels for all sound sources. This standard makes it possible
for all MIDI equipment to reproduce the same nuances when playing General MIDI
data, regardless of the manufacturer of the sound source.
Though the sound source of this keyboard is not General MIDI compatible, you can
still connect the keyboard to a computer or other MIDI equipment to playback
General MIDI data that is widely available in stores, over computer networks, and
from other sources.
Notes
•General MIDI data made up of a large number of parts may not play correctly on this
keyboard.
•You will have most success playing back General MIDI data that has few parts and is
made up of data on channels 1, 2, 3, 4, and 10.
Messages
There is a wide variety of messages defined under the MIDI standard, and this
section details the particular messages that can be sent and received by this keyboard. 
						

							E-38
NOTE ON/OFF
This message sends data when a key is pressed (NOTE ON) or released (NOTE OFF).
A NOTE ON/OFF message include a note number (to indicate note whose key is
being pressed or released) and velocity (keyboard pressure as a value from 1 to 127).
NOTE ON velocity is always used to determine the relative volume of the note. This
keyboard does not receive NOTE OFF velocity data.
Whenever you press or release a key on this keyboard, the corresponding NOTE ON
or NOTE OFF message is sent by constant velocity from the MIDI OUT terminal.
PROGRAM CHANGE
This is the tone selection message. PROGRAM CHANGE can contain tone data
within the range of 0 to 127.
A PROGRAM CHANGE message (0 to 99) is sent out through this keyboard’s MIDI
OUT terminal whenever you manually change its tone number. Receipt of a PRO-
GRAM CHANGE message from an external machine changes the tone setting of this
keyboard.
This keyboard can send tone data within the range of 00 to 99 and receive tone data
within the range of 0 to 127*.
*When GM mapping is turned on. When turned off, tone data is received in the
range of 0 to 99.
Note
•Channel 10 is for the drum part only, and it does not receive Program Change
messages.  When receiving MIDI data, it sounds percussion sounds produced by this
keyboard.
PITCH BEND
This message carries pitch bend information for smoothly sliding the pitch upwards
or downwards during keyboard play. This keyboard does not send pitch bend data,
but is can receive such data.
CONTROL CHANGE
This message adds effects such as vibrato and volume changes applied during
keyboard play. CONTROL CHANGE data includes a control number (to identify the
effect type) and a control value (to specify the on/off status and depth of the effect).
The following is a list of data that can be received using CONTROL CHANGE.
