Connecting phones cuts off output from the keyboard’s built­in speakers, so you can play even late at night without dis­turbing anyone.

Audio Equipment (Figure 2)

Connect the keyboard to a audio equipment using a com­mercially available connecting cord with a standard plug on
one end and two PIN plugs on the other end. Note that the
standard plug you connect to the keyboard must be a stereo
plug, otherwise you will be able to output only one of stereo
channels. In this configuration, you normally set the input
selector of the audio equipment to the terminal (usually
marked AUX IN or something similar) where the cord from
the keyboard is connected. See the user documentation that
comes with your audio equipment for full details.

Combination tones

Selecting a Tone

This keyboard comes with 100 built-in tones. Use the follow­ing procedure to select the tone you want to use.

To select a tone

1.

Find the tone you want to use in the keyboard’s
tone list and note its tone number.

The following describes the two types of combination tones
that are available.

Layered Tones (Tone Numbers: 80 through 89)

Example: 80 STR PIANO

This tone layers a strings tone with a piano tone so they both
sound when a keyboard key is pressed.

Split Tones (Tone Numbers: 90 through 96)

Example: 90 BASS/PIANO

This tone splits the keyboard so one range is assigned a bass
tone and another range is assigned a piano tone.

Sound Effect Tones

With sound effect tones 77 through 79, the type of sound pro­duced depends on the octave where the key you press is lo­cated. When 78 PHONE is selected available sound types are
PUSH TONE 1, PUSH TONE 2, RING 1, RING 2, and BUSY
SIGNAL.

Polyphony

The term polyphony refers to the maximum number of notes
you can play at the same time. The keyboard has 12-note po­lyphony, which includes the notes you play as well as the
rhythms and auto-accompaniment patterns that are played
by the keyboard. This means that when a rhythm or auto­accompaniment pattern is being played by the keyboard, the
number of notes (polyphony) available for keyboard play is
reduced. Also note that some of the tones offer only 6-note
polyphony.

❚

NOTE

• When rhythm or auto accompaniment is playing, the number
of sounds simultaneously played is reduced.

Digital Sampling

A number of the tones that are available with this keyboard
have been recorded and processed using a technique called
digital sampling. To ensure a high level of tonal quality, sam­ples are taken in the low, mid, and high ranges and then com­bined to provide you with sounds that are amazingly close
to the originals. You may notice very slight differences in
volume or sound quality for some tones when you play them
at different positions on the keyboard. This is an unavoid­able result of multiple sampling, and it is not a sign of mal­function.

IMPORTANT!

Howling (Feedback Noise)

Any of the following conditions can cause howling (feedback
noise).

Using the Microphone Jack
(CTK-491 only)

Connecting a commercially available microphone to the MIC
IN jack makes it possible to sing along with the keyboard’s
built-in tunes or with output from a MIDI device. When con­necting a microphone, be sure to first adjust the MIC VOL­UME to a relatively low setting, and then adjust to the level
you want after connecting.

1.

When connecting a microphone, we recommend

• Covering the head of the microphone with your hand

• Positioning the microphone too near to a speaker

Should howling occur, try grasping the microphone further
away from the head, and move away from any nearby speak­er.

Static Noise

Fluorescent lighting can cause static noise in the microphone
signal. When this happens, move away from the lighting you
suspect may be causing the static.

CHORD BOOK

The Chord Book feature of this keyboard makes it possible
for you to look up information about chords quickly and eas­ily. Simply input the name of the chord and the keyboard
keys you should press, the fingers you should use, and the
notes that make up the chord appear on the display along
with the chord name.

What is a chord?

A chord is made up of a root note, upon which is stacked a
number of other notes. A variety of different chords can be
created by changing the notes stacked onto a root.

<Example: C chord>

Chord Names

Chords are named using upper-case letters from A through
G, which indicate the root note of the chord. If the root note
is a sharp or flat, the chord itself is sharp or flat. A chord
name may also be followed by a degree number or other sym­bols that indicate certain characteristics about the chord.

Sharps and flats can be referred to using either
of the names shown here. The names in the
upper row of this illustration are used by this
keyboard, because they are the names that are
most commonly used in musical notation.

Inverted Forms

There are a number of different ways to play the same chord.
A form that is different from the basic form but still produces
the same chord is called an “inverted form.”

• You can also use the [+] and [–] buttons to change the dis-
played chord name.

• The tone used to sound chords you play on the accompani­ment keyboard while using the Chord Book is the same tone
used by the accompaniment part of the rhythm that was se­lected before you entered the Chord Book mode. Depending
on the rhythm that was selected, some of the notes that make
up a chord may be omitted when you play the chord on the
accompaniment keyboard in the Chord Book Mode. This is due

NOTE

• Since the chord fingerings that appear on the display are se­lected to allow chord play within the accompaniment keyboard,
inverted chord forms (page E-26) are often suggested. Invert­ed chord forms are useful to help you learn how to play chord
variations that make it possible to move from one chord to an­other with minimal hand movement. These forms come in handy
when using FINGERED Auto Accompaniment play.

• While a chord name is on the display, you can press keys on
the accompaniment keyboard to find out the fingerings of the
same chord with a different root.

• You can also scroll through chord names using the [+] and [–]
buttons.

• Chord fingerings that appear on the display are formed using
only the keys within the range of the accompaniment keyboard
(leftmost 18 keys). Chords that cannot be formed using the
keys within this range are not displayed.

MIDI

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) produced by different manufacturers. MIDI com­patible equipment can exchange keyboard 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 section 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 to send and receive data.

MIDI IN MIDI OUT

MIDI IN MIDI OUT

MIDI sequencer

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.
When sending operation of this keyboard to an external de­vice, Channel 1 should be selected as the MIDI send channel.

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.

❚

NOTE

• 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.

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.

❚

NOTE

• The pitch of a note depends on the tone that is being used, as
shown in the Note Table on page A-2. Whenever this keyboard
receives a note number that is outside its range for that tone,
the same tone in the nearest available octave is substituted.

TRANSPOSE/TUNE/MIDI

[+]/[–]

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 PROGRAM CHANGE
message from an external machine changes the tone setting
of this keyboard (this page).
This keyboard can send tone data within the range of 00 to
99 and receive tone data within the range of 0 to 127.

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.
