Welcome to the CBX-K2
Congratulations and thank you for purchasing the Yamaha CBX-K2 MIDI Keyboard!
The CBX-K2 is a sophisticated, yet compact MIDI keyboard controller, for use
with computers and MIDI music systems. It allows you to play connected tonegenerators 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 MIDIcontrols that allow you to send virtually any MIDI message directly from the
keyboard. Moreover, the CBX-K2 has three built-in assignable controllers: Assign-able Wheel, Assignable Slider and Assignable Footswitch. The Assignable Wheel
and Assignable Slider can be set to control virtually any parameter on your connected tone generator or sequencer in real time, while the Assignable Footswitch
can be used for sustain, certain sequencer controls, or as an alternate SHIFT button.
Because of its portable size, convenient battery/AC adaptor power supply, com-
patibility with General MIDI (GM) and XG, and extraordinarily powerful and
comprehensive MIDI control functions, the CBX-K2 is an invaluable tool — a
MIDI Swiss army knife, of sorts — for all MIDI musicians and performers.
IMPORTANT ■ The CBX-K2 does not contain an internal tone generator. In order
to play sounds from the CBX-K2, 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-K2 may not be sup-
ported 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-K2.

The CBX-K2 — What It Is and What It Can Do
What It Is
The CBX-K2 is a compact, highly portable 49-key MIDI
keyboard, designed especially for use with computers and
MIDI music systems. The CBX-K2 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-K2 is in its
comprehensive MIDI controls. The CBX-K2 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-K2 has an Assignable
Wheel and Slider 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-K2 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 or Slider on the CBX-K2, you have direct realtime 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-K2. 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-K2. 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-K2 is small enough to fit on top of nearly any
keyboard, making it perfect as a second keyboard. Since
the CBX-K2 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-K2 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
MU100R), the CBX-K2 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-K2 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-K2 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.

How to Use This Manual
By and large, the CBX-K2 is very easy to use and this manual is self-explanatory. However, we strongly recommend that you
take time to read the manual — especially before trying some of the more sophisticated MIDI functions. Read through all of
the initial sections first, then go on to the “Guided Tour” to set up your CBX-K2, learn how to use its various functions, and
try out some of the practical application examples to help you become more familiar with its operations. For those who need
to delve deeper, the “Reference” section provides at-a-glance information and important details on all functions.
The following conventions are used throughout this manual:
* Panel buttons and controls are indicated as they appear on the actual instrument. (For example, C and
M.
* The functions and features assigned to the keyboard are shown like this: T and {.
* Unless indicated otherwise, L refers to either of the ENTER keys, J or K. However,
when you wish to enter a decimal value, make sure to press K. Likewise, when entering a hexadecimal
number, make sure to press J.
* Actual MIDI data messages (in hexadecimal) are indicated as follows: <<FE>> and <<En 00 40>>, etc.
* Operation steps are indicated as follows:
ExampleActual Operation

PA-1D or an equivalent. Batteries can also be used (see
below). However, we strongly recommend that you use the
power adaptor.
NOTE
■ Before making any connections, make sure that
all equipment to be connected is turned off.
Using a Power Adaptor
Connect one end of the power adaptor (PA-1D) to the DC
IN jack on the rear panel, and the other end to a suitable
electrical outlet.
CAUTION!
other than the PA-1D (or another adaptor recommended by Yamaha) . The use of an incompatible
adaptor may result in irreparable damage to the CBXK2, and even pose a serious shock hazard.
■
Be sure to disconnect the power adaptor from the
outlet when the CBX-K2 is not in use.
■ Do not attempt to use a power adaptor

Setting Up Your CBX-K2
All the devices must be turned off before making connections.
In this introductory section, you’ll learn how to set up the
CBX-K2 for use in your music system. A variety of setups
are covered here; read through the one that most closely
matches your own setup.
What You’ll Need
Since the CBX-K2 is strictly a MIDI controller and does
not generate any sound by itself, you’ll need other datareceiving and sound-producing equipment. Basically, you
will need:
* The CBX-K2 and PA-1D AC power adaptor (or a set of
batteries).
* A MIDI device (such as a tone generator, keyboard or
computer) which can receive and play back MIDI data,
and at least one MIDI cable.
* (Optional) An amplifier/speaker system, preferably
stereo, with proper audio connecting cables. Alternately, you can use a set of stereo headphones.
Setup Examples
NOTE
■ All devices must be turned off before making
connections.

In the simple system below, the CBX-K2 is used to play the
voices of the MU100R Tone Generator. This setup could
also serve as a simple, yet powerful live performance rig,
with the CBX-K2 being used as a portable keyboard
controller.

Setting Up Your CBX-K2
With Main Keyboard and Tone Generator
In this system, the CBX-K2 effectively serves as a second
keyboard. The main keyboard (in this case, the Clavinova)
is used to play both its own internal sounds and the sounds
of the connected multi-timbral tone generator on one
channel, while the CBX-K2 is used to play the sounds of
the tone generator on another channel. This lets you play
two sounds at once from the Clavinova, and play a third
sound from the CBX-K2.

Making the Connections
CAUTION!
sure that all equipment to be connected is set to
minimum volume and turned off.
Operation
Connect the MIDI OUT terminal of the CBX-K2 to the
1.
MIDI IN terminal of the tone generator, sequencer or
computer MIDI interface (as shown in the illustrations
above).
Make all necessary audio connections, making sure first
2.
that all level controls on those devices are set to the
minimum. (Refer to the owner’s manuals of the devices
you are using for more information on connections.)
Turn the power on for the various equipment in the
3.
following order:
When turning off the power, simply reverse the above
order, turning off the CBX-K2 last.
■ Before making any connections, make
1) CBX-K2
2) Computer
3) Tone generator(s)
4) Audio devices (mixer, amplifier, etc.)
Connect the MIDI OUT terminal on the main keyboard to
the MIDI IN terminal on the CBX-K2. Also connect the
MIDI OUT terminal on the CBX-K2 to the MIDI IN terminal
on the tone generator.
In a variation of the above setup, set the Clavinova and
CBX-K2 to transmit on the same channel, and set the CBXK2’s MIDI Merge function to ON. This lets you play the
tone generator from either keyboard and use the versatile
MIDI functions of the CBX-K2 to control the tone generator — for example, changing the brightness of the sound in
real time with the Assignable Wheel.
NOTE
■ When an external MIDI device is connected to
the MIDI IN of the CBX-K2, the LED display may
indicate a MIDI error. This is probably due to a
longer-than-normal interval between active sensing
messages received from the device, or could be the
result of an improper connection. In such a case, the
CBX-K2 automatically resets to Merge Off (pages 26,
34). Check the connected device or cable before
continuing.

Playing and Using Your CBX-K2
This section of the manual guides you through some of the
basic features and functions of the CBX-K2. It also
provides some advanced operation examples, so that you
can get a feel for what the CBX-K2 is capable of, and how
you can best use it. Master the basics in this section, and
you’ll have the experience and know-how to easily and
confidently use any of the more advanced functions covered
later in the Reference section.
Selecting and Playing Voices
The CBX-K2 lets you select voices (or program numbers)
on your connected MIDI device in two ways: stepping up
or down through the program numbers, or directly selecting
a specific program number.
•To step up or down through the program numbers:
First, make sure that the program number is shown
in the display (see the Display Program Change
function, page 26). Then, simultaneously hold down
C and press M (to advance one
program number), or press N (to go
back one program number).
In this section, you’ll learn how to:
•Transmit program change messages and play the
keyboard.
•Select a voice bank.
•Change the octave setting of the keyboard.
•Use the Pitch Bend and Assignable Wheels.
•Re-assign the controller for the Assignable Wheel
and Slider.
•Change the Touch Sensitivity of the keyboard.
When the CBX-K2 is turned on, the starting point for
program change is 001. This means that when you first
hold down C and press M, program
number 002 will be selected.
IMPORTANT!
the CBX-K2 keyboard. Holding down C accesses
the secondary A or B group or other functions, and you
may inadvertently execute one of these functions by
playing the keyboard while continuing to hold down
C.
■
Always release C before playing
The program number in the LED display changes accordingly, and the OCTAVE SHIFT lamps quickly flash on and
off. Release C, and play the keyboard to hear the
newly selected voice.
To quickly move up or down through the program numbers,
continuously hold down C and the appropriate OC-TAVE SHIFT button.
NOTE
■ This function does not “wrap around.” In
other words, you cannot go back to program number
128 when at 001, or advance to program number 001
when at 128.
•To change the program number:
While holding down C, press the key corresponding to Y (F1), then the keys
corresponding to the desired number, then the key
corresponding to K.
For example, to select program number 017, continue
holding down C and press Y, 1,
7, then K. Release C, and play the key-
board to hear the newly selected Voice.
16
Playing and Using Your CBX-K2
Changing the Voice Banks
Many currently available tone generators feature multiple
banks of voices. The CBX-K2 can be used to quickly and
easily select these additional banks. Some banks may not
be available on your particular tone generator; check the
manual for details.
Operation
Simultaneously hold down C and press
1.
T.
The LED display indicates the current Bank setting by
alternately flashing the MSB and LSB values. (In this
case, the default setting, both of these values are 000.)
MSB valueLSB value
The display alternately flashes the
MSB and LSB values.
While continuing to hold down C, enter the
2.
number 64 (press 6, then 4), then press
K.
MSB valueLSB value
This sets the Bank to 064 (LSB value). The LED
display alternately flashes the MSB and LSB values,
000 and 064.
To restore the original Bank (or select other Banks), hold
down C, press T, 0 (or another number
for a different Bank), and K.
Changing the Octave Range
The range of the 4-octave keyboard can be easily shifted up
or down to cover the full 10-1/2-octave (128-note) range of
MIDI notes. (See on page 9 for the note range.)
Operation
To shift the keyboard up one octave, press
M. To shift the keyboard down one
octave, press N.
When the octave range is changed, the LED display briefly
indicates the new setting. The OCTAVE SHIFT lamps
also rapidly flash one or more times, according to the
selected octave range. For example, when the setting is
changed to two octaves below normal, the left lamp flashes
twice.
You can instantly restore the normal octave range by
pressing both N/M buttons
simultaneously.
NOTE
■ At the highest octave setting, keys outside the
legal MIDI note range will repeat a previous octave.
17
Playing and Using Your CBX-K2
Using the Pitch Bend Wheel, Assignable Wheel, and Assignable Slider
These two wheels and slider let you control different
aspects of the sound in realtime as you play. These controls affect the connected MIDI instrument.
Move the Pitch Bend Wheel as you play to change the pitch
of the sound. Moving the wheel away from you bends the
Re-assigning the Assignable Wheel and Slider
As mentioned above, the Assignable Wheel and Slider can
be used to control a variety of different functions. The
default setting for the Wheel is modulation (MIDI Controller #1), and the default for the Slider is data entry (MIDI
Controller #6). However, either can be set to control
volume, pan position, attack or release time, coarse tuning
or fine tuning, and reverb or chorus depth, among other
Controllers. (For a complete list of the available Controllers and their numbers, see on page 30.)
Assignable Wheel / Operation
Simultaneously hold down C and press
1.
S in the fi section.
The LED display indicates the current Assignable
Wheel’s Controller number.
While continuing to hold down C, enter the
2.
number 10 (press 1, then 0), then press
K.
This sets the Assignable Wheel to Controller number 10
(Pan). Play the keyboard and move the Assignable Wheel
as you play, and hear how the sound moves left and right in
the stereo image as you move the Wheel. As you move the
Wheel, the currently assigned Controller number appears in
the LED display. The Assignable Wheel is particularly
pitch up. The Pitch Bend Wheel is spring-loaded for
returning to center (normal pitch).
Move the Assignable Wheel as you play to change the
modulation of the sound (MIDI Controller #1). Moving the
wheel away from you increases the modulation. Moving
the Assignable Slider changes the Data Entry value (MIDI
Controller #6). (Notice that the “006” flashes in the
display, indicating data for Controller #6 is being transmitted.) The Assignable Wheel and Assignable Slider can also
be set to control other functions; see the section below for
details.
Depending on the connected device and the selected voice,
there may be no response or change in the sound. Refer to
the owner’s manual of the particular device for details.
suited to control numbers such as #10 (Pan) and #73
(Attack Time) because of its center detent.
Try entering other Controller numbers, repeating steps 1
and 2 above. (A short list of Controllers is printed on the
panel. Try entering some of these; many—but not all—of
these will have an obvious effect on the sound as you move
the wheel.)
Assignable Slider / Operation
Simultaneously hold down C and press
1.
Sin the ‡ section.
The LED display indicates the current Assignable
Slider’s Controller number.
While continuing to hold down C, enter the
2.
desired Controller number (for example, “7” for
MIDI volume control), then press K.
Play the keyboard and move the Assignable Slider as
you play, and hear how the volume of the sound
changes (if you are using Controller #7).
* You can also assign RPN and NRPN numbers to the
Assignable Wheel or Slider. (Pages 26 and 30.)
18
Playing and Using Your CBX-K2
Changing the Touch Sensitivity of the Keyboard
The Touch Sensitivity function lets you change how the
Voices respond to your playing strength.
NOTE
■
Touch Sensitivity is a “Group B” function. The
“Group A” functions (such as Program Change, Bank
Select, and Controller, which were covered above) are
shown on the panel and explained in detail on pages 26
– 27. The Group B functions (listed and explained on
pages 28 – 29) are also shown on the panel but are
accessed differently than Group A functions.
Operation
Simultaneously hold down C, press ç,
1.
then ˙.
Pressing ç first (before any function key) calls
up the Group B functions. The LED display indicates
the current Touch Sensitivity value.
While continuing to hold down C, enter the
2.
number 1, then press K.
This sets Touch Sensitivity to 1 (easy). Now, when you
play the keyboard, even playing softly results in a
reasonably loud sound.
Try entering other values (the range is 1–10), and hear how
they affect the response of the keyboard. The default value
is 10, and can also be restored by simply turning the CBXK2 off and on again.
NOTE
■ When Fixed Velocity is set to a value other
than 0 (off), the Touch Sensitivity setting has no effect.
For more information on Touch Sensitivity, see footnote #5
on page 28.
This concludes the basic tour of some of the important functions of the CBX-K2. To find out more about

The MIDI functions can be generally divided into three
types, according to their operation.
Holding C and pressing the function’s key. For
1)
these functions, such as Sequencer Stop and Start,
pressing L is not necessary. These functions are
shown on the panel without underline.
Holding C, pressing the function’s key and then
2)
L. These functions are indicated with a dashed
underline on the panel (for example, GM ON and XG
ON) and require pressing L to execute.
Holding C, pressing the function’s key, entering
3)
a value and then pressing L. These functions
are indicated with an underline on the panel (for example, PROGRAM CHANGE and TEMPO), and
require that a value (Decimal or Hexadecimal) be
entered.
When changing a function, the LED display indicates
the on/off status or the value of the function.
In using the SHIFT-related functions, remember
Keep holding down C until the end of the
operation. If C is released in mid-operation,
you’ll have to start the operation all over again.
In the instructions that follow, “L” refers to either of
the ENTER keys, J or K. In other
words, this means that either key can be used, unless
indicated otherwise.
NOTE
■ Both N / M
lamps flash briefly when a function is executed. The
LED display flashes briefly when a MIDI message is
sent.

Basic Operations
Using the SHIFT-Related Functions
Selecting Group A and Group B Functions
● Selecting Group A Functions:
Hold down C and press the appropriate key. (See
on pages 26 – 27 for specific Group A functions and
how to use them.)
● Selecting Group B Functions:
Hold down C and press ç. The Group B
functions are available as long as you continue to hold
down C. (See on pages 28 – 29 for specific Group
B functions and how to use them.)
Entering Values
Value entry on the CBX-K2 can be done in two number
systems: Decimal and Hexadecimal. The keys labeled A
through F are for Hexadecimal entry.
● Entering a decimal value:
Hold down C, press the appropriate function key,
enter the desired value in decimal format, then press
K.
● Entering a hexadecimal value:
Hold down C, press the appropriate function key,
enter the desired value in hexadecimal format, then
press J.
Example — Setting the MIDI Transmit Channel to 12:
Decimal:
C + { → 1 → 2 → K
Hexadecimal:
C + { → c → J
* Also see the Decimal-Hexadecimal Conversion Chart
on page 33.)
Value Entry — Some Specific Examples
and Anomalies
● Entering MSB/LSB Values with K (3 digit bytes
for MSB, 3 digit bytes for LSB; 6 digits total message).
For messages beginning with zeroes, the first zeroes
can be omitted.
Examples:
* 3→K
* 0→3→K: results in a value of MSB = 000, LSB =
003.
: results in a value of MSB = 000, LSB = 003.
* 1→0→0→3→K: results in a value of
MSB = 001, LSB = 003.
* 0→1→0→0→3→K: results in a
value of MSB = 001, LSB = 003.
● Entering MSB/LSB Values with J (2 digit
bytes for MSB, 2 digit bytes for LSB; 4 digits total
message). For messages beginning with zeroes, the
first zeroes can be omitted.
Examples:
* 3→J: results in a value of MSB = 00, LSB = 03.
* 0→3→J: results in a value of MSB = 00,
LSB = 03.
* 1→0→3→J: results in a value of MSB
= 01, LSB = 03.
* 0→1→0→3→J: results in a value
of MSB = 01, LSB = 03.
When entering MSB and LSB values, the LED display
alternately flashes the MSB and LSB values in hexadecimal
or decimal form.

reversed. (See MSB 1ST/LSB 1ST on page 28.)
NOTES ON THE BASIC OPERATION
■
If you inadvertently press two or more function keys
while performing a function, the last pressed key has
priority.
■
If, after entering a value, you press another function
key before pressing L, the value will be cancelled.
■
If you enter a value that is outside of a function’s
range, it will be ignored. Legal messages can be one
byte in length (a value from 0 – 255) exception for
Tempo value and Measure Number.
