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 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-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
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:
Example Actual Operation
C + E While holding down the C button, press E (D1).
C + U → L While holding down the C button, first press U (Fm1), then
press L (either J or K).

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.

The setup examples below show only the MIDI
connections. The audio connections would vary
according to the particular equipment you use. Refer
to the owner’s manuals of your other equipment for
audio connection instructions.
With Computer and Tone Generator
In the small MIDI system below, the CBX-K2 is connected
to a computer and a single tone generator. With the proper
sequencing software on the computer, the CBX-K2 can be
used both for recording performance data to the computer
and playing the sounds of the connected tone generator.
You can also conveniently use the CBX-K2 to start and stop
the sequencer.
For tone generators with a built-in MIDI interface (such as
the Y amaha MU100R)

When connecting the instrument to other MIDI devices, be
sure to use only high-quality MIDI cables. Also, avoid
using cables longer than 15 meters, since long cables can
result in data errors.
The HOST SELECT switch
on the MU100R allows you
to match the type of
computer, when connecting
directly to a computer.
Connect the MIDI OUT terminal on the CBX-K2 to the
MIDI IN terminal on the MU100R. The MU100R should be
connected to the proper port on the computer. (For
complete connection instructions, refer to the owner’s
manual of your particular tone generator.)

With Tone Generator
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.
