Welcome to the CBX-K1

Congratulations and thank you for purchasing the Yamaha CBX-K1 MIDI Keyboard!

The CBX-K1 is a sophisticated, yet compact MIDI keyboard controller, for use with
computers and MIDI music systems. It allows you to play connected tone generators
and rhythm machines, and enter performance data to sequencers and computers. It
features a sophisticated touch-sensitive keyboard that can be adjusted to cover the full

128-note MIDI range. It also provides a wealth of MIDI controls that allow you to
send virtually any MIDI message directly from the keyboard. Moreover, the CBX-K1

has a versatile ASSIGNABLE Wheel that lets you control a wide variety of parameters
on your connected tone generator or sequencer in real time. Because of its exceptionally

portable size, convenient battery/AC adaptor power supply, compatibility with Gen-
eral MIDI (GM) and XG, and extraordinarily powerful and comprehensive MIDI
control functions, the CBX-K1 is an invaluable tool — a MIDI Swiss army knife, of sorts

— for all MIDI musicians and performers.

IMPORTANT ■ The CBX-K1 does not contain an internal tone generator. In order to
play sounds from the CBX-K1, you need an external tone generator, such as the
Yamaha MU series or TG series tone generators.

NOTE ■ The many MIDI functions and features of the CBX-K1 may not be supported

by your particular MIDI device. Be sure to refer to the owner’s manual of your par­ticular MIDI device when using it with the CBX-K1.

The CBX-K1 — What It Is and What It Can Do

What It Is

The CBX-K1 is a compact, highly portable 37-key MIDI
keyboard, designed especially for use with computers and
MIDI music systems. The CBX-K1 does not generate any
sound itself, but can be used as a keyboard controller for
playing sounds on a connected tone generator or rhythm
machine. It’s also ideal for recording to sequencers and
computers. The keyboard is touch-sensitive and its octave
range can be changed to cover the full 128-note MIDI
range.

The true power and flexibility of the CBX-K1 is in its
comprehensive MIDI controls. The CBX-K1 allows you to
send virtually any type of MIDI message to connected
MIDI devices. Pre-programmed commands provide easy
control of basic sequencer/rhythm machine functions such
as Start, Stop, Tempo and Song Select, while comprehen­sive program change commands let you easily select
program banks and voices.

Most importantly, though, the CBX-K1 has an ASSIGN­ABLE Wheel that can be set for control of any controller
number. This means that you can use the ASSIGNABLE
Wheel to control a wide variety of parameters on your
connected tone generator — such as Volume, Pan, Bright­ness, and the Depth of various effects — in real time. This
gives you expressive control over different aspects of the
sound in live performance.

The CBX-K1 is also the latest instrument in the Yamaha
line to support the XG format, a new addition to the
General MIDI standard. In short, XG provides for more
instrument sounds and variations, and greater expressive
control over voices and effects. With the use of the
ASSIGNABLE Wheel on the CBX-K1, you have direct
real-time control over many of these newly supported
functions and parameters.

What It Can Do

Here are a few application ideas on how you can use the
CBX-K1. The list below is not comprehensive, but is
meant to be a general guide to the possibilities and provide
a starting point or springboard for your own creative ideas
and explorations.

● Using With a MIDI Tone Generator

In one of the most basic setups, you can play a connected
tone generator from the CBX-K1. Because it’s so compact
and portable, you can even use it as a hand-held keyboard
for live performance.

● Using as a Second Keyboard or Dedicated

MIDI Controller

The CBX-K1 is small enough to fit on top of nearly any
keyboard, making it perfect as a second keyboard. Since
the CBX-K1 has a MIDI IN terminal, you can connect it
between your main keyboard and your tone generator, and
use the extensive MIDI capabilities of the CBX-K1 for
greater expressive control during your performance.

● Using in a MIDI Music System

Combined with a laptop computer and a compact tone
generator (like the General MIDI/XG-compatible Yamaha
MU80), the CBX-K1 gives you comprehensive music
making power — for recording, composing, arranging,
practicing, and editing — in a portable system that’s ready
to go wherever you go. The CBX-K1 is an ideal addition
to larger MIDI studios as well, since it provides far greater
MIDI control and flexibility than nearly any other keyboard
controller. Use it along side your main MIDI keyboard as a
kind of MIDI Swiss army knife — sending necessary MIDI
messages, working the real-time controllers, or editing
already recorded sequencer tracks.

● Multimedia

Since it’s portable and compatible with the General MIDI
and XG formats, the CBX-K1 is a natural for multimedia
applications. Because of its ease of use and comprehensive
functions, it’s the only keyboard you’ll ever need for
recording and editing MIDI data on your multimedia
creations.

Precautions

Your CBX-K1 will give you years of reliable service if you
follow the simple precautions below:

● LOCATION

Keep the instrument away from locations where it is likely
to be exposed to high temperatures (such as direct sunlight)
or humidity. Also avoid locations which are subject to
excessive dust accumulation or vibration which could
damage the instrument.

● USE THE CORRECT POWER ADAPTOR

Use only the recommended PA-1B or PA-3 Power Adaptor
for supplying power. Use of another adaptor may cause
serious damage to the instrument or the adaptor itself. Also
avoid using a multiple-plug adaptor; plug the adaptor
directly into a wall outlet.

● MAKE SURE POWER IS OFF WHEN MAKING

OR REMOVING CONNECTIONS

To prevent damage to the instrument and other connected
equipment, always turn off the power prior to connecting or
disconnecting cables. Also, turn the power off when the
instrument is not in use, and disconnect the power adaptor
during electric storms.

● ELECTROMAGNETIC INTERFERENCE

Avoid using the unit near televisions, radios or other
equipment generating electromagnetic fields. Proximity to
such equipment may cause the unit to malfunction, and may
generate interference noise in the other appliance as well.

● DO NOT OPEN THE CASE OR TRY REPAIRING

THE INSTRUMENT YOURSELF

The instrument contains no user-serviceable parts. Never
open the case or tamper with the internal circuitry in any
way, since doing so may result in damage to the instrument.
Refer all servicing to qualified Yamaha service personnel.

● MIDI CABLES

When connecting the instrument to other MIDI equipment,
be sure to use only high-quality cables made especially for
MIDI data transmission. Also, avoid using cables longer
than 15 meters, since long cables can result in data errors.

Yamaha is not responsible for damage caused by
improper handling or operation.

● NO MEMORY BACKUP

The CBX-K1 has no internal memory backup. As a result,
all settings are returned to the factory default when turning
the power off.

● HANDLE THE INSTRUMENT WITH CARE

Although the instrument has been constructed to withstand
the rigors of normal use for optimum sturdiness and
reliability, avoid subjecting it to strong physical shocks
(such as dropping or hitting it). Since the CBX-K1 is a
precision-made electronic device, also avoid applying
excessive force to the various controls. When moving the
instrument, first unplug the power adaptor and all other
cables to prevent damage to cords and jacks. Always
unplug cables by gripping the plug firmly, not by pulling
on the cable.

● CLEAN WITH A SOFT, DRY CLOTH

Never use solvents such as benzine or thinner to clean the
instrument, since these will damage the cabinet finish or
dull the keys. Wipe clean with a soft, dry cloth. If neces­sary, use a soft, clean, slightly moistened cloth — making
sure to wipe the instrument off again with a dry cloth. Do
not leave vinyl on the panel as this may stick to and
discolor the surface.

q Keyboard

The CBX-K1 has a 37-key, 3-octave keyboard (C2 to C5),
featuring initial touch (velocity) control. All note on, note
off and velocity data is transmitted via the MIDI OUT
terminal. When used with the C button, the keys are
used for changing various settings and sending special
MIDI messages. (See page 12.)

About the Functions of the CBX-K1: The functions are

divided into two groups: Group A and Group B. The
Group A functions are shown on the panel, above the
left section of the keyboard. The Group B functions are
“hidden” and are listed on pages 12 and 20. Several
functions can be used by pressing only the relevant key;
in other words, pressing L is not necessary. These
functions, such as Sequencer Stop and Start, are shown
on the panel without underline. The right section of the
keyboard serves as value entry and is used for those
functions whose names are underlined on the panel and
require value entry, such as Program Change and
Tempo. Functions whose names appear with a dashed
underline on the panel (for example, GM ON and XG
ON) require pressing L. Value entry on the CBX­K1 can be done in two number systems: Decimal and
Hexadecimal. The keys labeled A through F are for
Hexadecimal entry.
