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 ■ 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:

Example

C + E

C + U → L

Actual Operation

While holding down the C button, press E (D1).

While holding down the C button, first press U (F m 1), then press L (either J or K ).

Setting Up the CBX-K2 in Your Music System

Whatever your system, you should follow the basic instructions below when setting up your CBX-K2. Use the example illustrations as a general guide when making the connections with your own system.

Power Supply

Your CBX-K2 will run from the included power adaptor,

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 Batteries

To use the CBX-K2 on battery power, remove the battery compartment cover (as shown below) and insert six 1.5V

AA size (SUM-3, R-6 or equivalent) batteries in the battery compartment. Make sure to follow the polarity indications on the bottom case.

Battery compartment cover

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! ■ Do not attempt to use a power adaptor other than the PA-1D (or another adaptor recommended by Yamaha) . The use of an incompatible adaptor may result in irreparable damage to the CBX-

K2, 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.

DC IN

STANDBY ( ?

)

Securely replace the battery compartment cover when done installing the batteries.

When to Replace the Batteries

When the battery power runs too low to properly operate the CBX-K2, an “E1” message appears in the LED display.

When this happens, replace all batteries with a complete set of six new batteries of the same type.

CAUTION! ■ NEVER mix old and new batteries or different types of batteries! Also, to prevent possible damage due to battery leakage, remove the batteries from the instrument if it is not to be used for a long time.

Power adaptor

12


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.

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.

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.

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.

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 CBX-

K2’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.


Making the Connections

CAUTION! ■ Before making any connections, make sure that all equipment to be connected is set to minimum volume and turned off.

Operation

1.

Connect the MIDI OUT terminal of the CBX-K2 to the

MIDI IN terminal of the tone generator, sequencer or computer MIDI interface (as shown in the illustrations above).

2.

Make all necessary audio connections, making sure first 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.)

3.

Turn the power on for the various equipment in the following order:

1) CBX-K2

2) Computer

3) Tone generator(s)

4) Audio devices (mixer, amplifier, etc.)

When turning off the power, simply reverse the above order, turning off the CBX-K2 last.

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.

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.

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).

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! ■ Always release C before playing 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.

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.

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.

• 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 keyboard to hear the newly selected Voice.

16


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

1.

Simultaneously hold down C and press

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.)

2.

While continuing to hold down C, enter the number 64 (press 6, then 4), then press

K.

MSB value LSB 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.

MSB value LSB value

The display alternately flashes the

MSB and LSB values.

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


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 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.

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

1.

Simultaneously hold down C and press

S in the fi section.

The LED display indicates the current Assignable

Wheel’s Controller number.

2.

While continuing to hold down C, enter the 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

18 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

1.

Simultaneously hold down C and press

S in the ‡ section.

The LED display indicates the current Assignable

Slider’s Controller number.

2.

While continuing to hold down C, enter the 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.)


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

1.

Simultaneously hold down C, press ç, then ˙.

Pressing ç first (before any function key) calls up the Group B functions. The LED display indicates the current Touch Sensitivity value.

2.

While continuing to hold down C, enter the 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 CBX-

K2 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 how to use your CBX-K2, look through the Reference section that follows and try out some of the functions and operations that interest you.

19


The enormous flexibility and power of the CBX-K2 is in its

“hidden” or SHIFT-related functions — allowing you to send virtually any kind of MIDI message directly from the keyboard or use the Assignable Wheel/Slider for real-time control change.

Many of the functions can be done with one or two keystrokes, while others require you to enter a number value and press one of the L keys to execute the function.

All functions can be accessed or executed by using one of the operations described below.

The MIDI functions can be generally divided into three types, according to their operation.

1)

Holding C and pressing the function’s key. For these functions, such as Sequencer Stop and Start, pressing L is not necessary. These functions are shown on the panel without underline.

2)

Holding C, pressing the function’s key and then

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.

3)

Holding C, pressing the function’s key, entering 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

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

● 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.

NOTE ■ The order of MSB and LSB entry can be reversed. (See MSB 1ST/LSB 1ST on page 28.)

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 : results in a value of MSB = 000, LSB = 003.

* 0

→

3

→

K : results in a value of MSB = 000, LSB =

003.

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.

The operation steps enclosed in braces ({}) can be repeated or re-entered as long as C is held.

NOTE ■ This operation assigns a controller number for the Assignable Wheel or Slider, and sends a specific value for that controller number. You can also send a specific value for the controller (in the Group B functions) without altering the controller assignment.

6

Transpose Setting

Operation: C + G / H

To transpose up one semitone, use the H key

(F2). To transpose down one semitone, use the

G key (E2). Each repeated pressing of the key while holding C transposes the pitch by an additional semitone. To restore the normal default transpose setting, hold down C and press both

G / H keys simultaneously.

NOTE ■ You can also enter transpose values directly by using operation above.

8

Selecting a Drum Number (when editing a specific drum number with controller numbers 136 – 151)

You can use operation above to set the drum number for editing a specific drum number with controller numbers

136 – 151. However, the following operation lets you set the Drum number by playing it from the keyboard. This allows you to hear the drum sound you’ll be editing, since the last note played on the keyboard determines the drum sound to be changed.

Without pressing C, find the desired drum number by sound — by pressing keys on the keyboard. Next, hold down C, press F, then L. This sets the drum number to the last key pressed. Then (to set the controller number for that drum sound), hold down C and press S, then enter the controller number

(136 through 151). This sets the Controller Number for the

Drum parameter you wish to control with the Assignable

Wheel or Slider.

● Footnotes

*1 The operation steps in braces ({}) can be repeated or re-entered as long as C is held.

*2 Depending on the selected message or the particular device that is connected to the CBX-K2, there may be no response. Refer to the owner’s manual of the device for details.

*3 Be careful not to press the connected footswitch when footswitch is assigned to “SUS”; the operation cannot be executed while the footswitch is pressed.

*4 When Tempo is assigned to the Assignable Wheel or Slider, this setting is ignored. When the Assignable Wheel or Slider is set to a function other than Tempo, the current value is effective. The range for this function is 20 – 300 bpm; when the Wheel or Slider is set to control Tempo, the range is slightly narrower: 28 – 282 bpm. When this is set to 0, “oFF” is shown in the display.

*5 The entry order of the MSB and LSB values can be changed by using the MSB 1ST/LSB 1ST in Group B.

*6 The actual program change number transmitted by the CBX-K2 is the displayed number minus one. For example, program number 001 on the display is actually transmitted as 000.

*7 The value can also be easily increased or decreased. First, make sure that the display is set appropriately (to Program Change or Bank

*8 The connected device initializes itself upon reception of this message.

*9 When a MIDI error results, MIDI Merge is automatically set to OFF.

*10 • When RPN or NRPN is assigned, the Wheel or Slider is automatically set to control Data Entry and will change the relevant parameter on the connected device.

• To send a specific value for the current control number assignment of the Wheel or Slider, hold down C, enter the desired value, and press L. However, this cannot be done with the following controller numbers: 153 (Key Pressure), 157 (Velocity), or 158

(Tempo).

• The assigned MSB and LSB values alternately appear in the LED display. When no value is assigned, “---” is shown in the display.

*11 Transpose can be done in two ways: by repeatedly pressing

G or H key or by entering the transpose value directly after pressing G or H key.

To restore the normal transpose setting, hold C and press both fl keys simultaneously.

● Footnotes

*1 Depending on the selected message or the particular device that is connected to the CBX-K2, there may be no response. Refer to the owner’s manual of the device for details.

*2 The Time Signature Top value is selected in the following order: 4, 5,

6, ... 15, 16, 1, 2, 3, 4, etc. (“4” is used as the starting point, since that is the most commonly used Top value.) The order for the Time

Signature Bottom values is 4, 8, 16, 4, etc.

*3 The range for the Measure function depends on the currently set Time

Signature. When set to 4/4, the range is 1 – 999; when set to 8/4 or

16/8, the range is 1 – 512. The absolute maximum is 999.

*4 • The channel number can only be entered as a hexadecimal value (1

– F, 0).

• Using system exclusive messages to turn Merge on or off can only be done for all channels (as in the corresponding Group A function).

*5 When Fixed Velocity (in Group A) is set to a value other than 0, the

Touch Sensitivity function is inactive. The following table shows the velocity range for the minimum, medium, and maximum Touch

Sensitivity settings.


Explanation

Song Select command for sequencer/rhythm machine.

This determines the top (numerator) value of the time signature for sequencer/rhythm machine, at the specified song position (see Measure Number below). When song position is received this data will be used.

This determines the bottom (denominator) value of the time signature for sequencer/rhythm machine, at the specified song position (see Measure Number below). When song position is received this data will be used.

This determines the measure number (song position) for sequencer/rhythm machine. This is used together with the Time Signature functions above, and should be entered before specifying the Time Signature.

This determines the Voice Map setting when used with the Yamaha MU100R Tone Generator.

(For details, see the MU100R Owner’s Manual.)

Sets the connected tone generator to Poly or Mono mode.

This resets all MIDI controller values on the connected device to their reset values (minimum or center).

This turns all sounds off over all MIDI channels. To turn all sounds off for a single specific

MIDI channel, use the All Sound Off function in Group A.

This performs a TG300B reset on a connected tone generator.

This merges all data received over the specified MIDI channel with the data generated by the

CBX-K2. This function can be set independently for each channel. (For details about MIDI

Merge, refer to page 34.)

This determines the Device Number when independently transmitting certain messages (such as XG On) to one of several connected MIDI devices.

This determines the relative velocity sensitivity of the CBX-K2 keyboard. The lower the Touch

Sensitivity value, the higher the output velocity becomes. In other words, when this is set to a value near 1, even soft playing strength results in a loud sound from the connected tone generator. (1: easy - 10: hard)

This allows you to directly send a specific value for a selected RPN controller number, without altering the current controller assignment of the Assignable Wheel or Slider.

This allows you to directly send a specific value for a selected Control Change controller number, without altering the current controller assignment of the Assignable Wheel or Slider.

This allows you to directly send a specific value for a selected NRPN controller number, without altering the current controller assignment of the Assignable Wheel or Slider.

This determines the density of the data sent by the Assignable Wheel when it is set to a continuous controller (such as modulation or volume). Set this to a value at or near 1, when you wish to limit the amount of data sent (for example, when sequencer memory limits the amount of data that can be recorded). (1: thin - 10: thick or full)

This inverts the MSB/LSB value entry (so that LSB precedes MSB). You can also set this to

LSB 1ST by simultaneously holding down N and turning on the power.

This determines the function for the connected footswitch. Available functions are: Sustain

(SUS), Continue/Stop for sequencer (Cnt), Start/Stop for sequencer (StA), SHIFT button operation (SFt).

This determines the density of the data sent by the Pitch Bend Wheel.

This determines the density of the data sent by the Assignable Slider when it is set to a continuous controller (such as modulation or volume). Set this to a value at or near 1, when you wish to limit the amount of data sent(for example, when sequencer memory limits the amount of data that can be recorded). It can also be used to create special “step” effects for certain controller numbers. (1: thin - 10: thick or full)

This sends a data message of a single byte.

About MIDI

MIDI is an acronym that stands for Musical Instrument

Digital Interface, which allows electronic musical instruments to communicate with each other, by sending and receiving compatible Note, Control Change, Program

Change and various other types of MIDI data, or messages.

The CBX-K2 can control a MIDI device by transmitting note related data and various types of controller data.

MIDI Messages Transmitted by the CBX-K2

MIDI messages can be divided into two groups: Channel messages and System messages. Below is an explanation of the various types of MIDI messages which the CBX-K2 can receive and transmit.

Depending on the particular device that you are using, some messages may not be available. Refer to the owner’s manual of the device for details.

CHANNEL MESSAGES

Channel messages are the data related to the performance on the keyboard for the specific channel.

■ Note On/Note Off (Key On/Key Off)

Messages which are generated when the keyboard is played.

Transmission note range = C-2 (0) - G8 (127), C3 = 60

Velocity range = 1 - 127 (only Note On velocity is transmitted)

Note On: Generated when a key is pressed.

Note Off: Generated when a key is released.

Each message includes a specific note number which corresponds to the key which is pressed, plus a velocity value based on how hard the key is struck.

■ Bank Select

● Bank Select MSB (Control #000)

● Bank Select LSB (Control #032)

Messages (MSB/LSB) which set the voice bank of a tone generator.

When used on an XG-compatible tone generator set to

XG operation, normal or drum voice bank is selected by the MSB value, and the particular voice bank is selected by the LSB value. With Yamaha MU-series instruments, bank select will not function when a GM System On message is received.

■ Control Change

Control Change messages let you control volume, panning, modulation, portamento time, brightness and various other controller parameters, through specific Control Change numbers which correspond to each of the various parameters.

● Modulation (Control #001)

Messages which control vibrato depth using the Modulation Wheel.

Setting the value to 127 produces maximum vibrato and

0 results in vibrato off.

● Portamento Time (Control #005)

Messages which control the duration of portamento, or a continuous pitch glide between successively played notes.

Setting the value to 127 produces maximum portamento time and 0 results in minimum portamento time.

Portamento is turned on/off by Control #065.

● Data Entry MSB (Control #006)

● Data Entry LSB (Control #038)

Messages which set the value for the parameter specified by RPN or NRPN MSB/LSB. Parameter value is determined by combining MSB and LSB.

● Main Volume (Control #007)

Messages which control the volume.

Setting the value to 127 produces maximum volume and

0 results in volume off.

● Pan (Control #010)

Messages which control the stereo panning position of each voice (for stereo output).

Setting the value to 127 positions the sound to the far right and 0 positions the sound to the far left.

● Expression (Control #011)

Messages which control intonation expression of each voice during performance.

Setting the value to 127 produces maximum volume and

0 results in volume off.

● Sustain Switch (Control #064)

Messages which control sustain on/off.

Setting the value between 64 - 127 turns the sustain on, between 0 - 63 turns the sustain off. On the CBX-K2, a connected footswitch can be assigned to control sustain when “SUS” is set.

31

About MIDI

● Portamento Switch (Control #065)

Messages which control portamento on/off.

Setting the value between 64 -127 turns the portamento on, between 0 - 63 turns the portamento off.

● Sostenuto Switch (Control #066)

Messages which control sostenuto on/off.

Setting the value between 64 - 127 turns sostenuto on, between 0 - 63 turns sostenuto off.

When notes are held before and during the time sostenuto is turned on, those notes (and only those notes) will be sustained until sostenuto is turned off.

● Soft Pedal Switch (Control #067)

Messages which control soft pedal on/off.

Setting the value between 64 - 127 turns soft pedal on, between 0 - 63 turns soft pedal off.

When soft pedal is on, the sound becomes softer and lower in volume.

● Harmonic Content (Control #071)

Messages which adjust the VCF resonance set for each voice.

Higher values will result in a more characteristic, resonant sound. Depending on the voice, the effective range may be narrower than the range available for adjustment.

● Release Time (Control #072)

Messages which directly adjust the AEG release time set for each voice.

● Attack Time (Control #073)

Messages which directly adjust the AEG attack time set for each voice.

● Brightness (Control #074)

Messages which directly adjust the VCF cutoff frequency set for each voice.

Lower values will result in a softer sound. Depending on the voice, the effective range may be narrower than the range available for adjustment.

● Effect1 Depth (Reverb) (Control #091)

Messages which adjust the send level for the Reverb effect.

● Effect3 Depth (Variation Chorus) (Control #093)

Messages which adjust the dry/wet balance for the

Chorus Variation Effect.

● Effect4 Depth (Variation Depth) (Control #094)

Messages which adjust the send level for the Variation

32 depth.

● Data Increment (Control #096)

● Decrement (Control #097) for RPN

Messages which increase or decrease the value of Pitch

Bend Sensitivity, Fine Tune, or Coarse Tune.

You must assign one of those parameters using the RPN in the external device in advance.

● RPN (Registered Parameter Number) LSB (Control

#100)

● RPN (Registered Parameter Number) MSB (Control

#101)

Messages which offset, or add or subtract values from the Pitch Bend Sensitivity, Fine Tune, or Coarse Tune parameters.

First send the RPN MSB and RPN LSB to specify the parameter which is to be controlled. Then use Data

Increment/Decrement to set the value of the specified parameter.

Note that once the RPN has been set for a channel, subsequent data entry will be recognized as the same

RPN’s value change. Therefore after you use the RPN, you should set a Null (7FH, 7FH) value to avoid an unexpected result.

Messages which can be transmitted are as follows:

● All Sounds Off (Control #120)

Clears all sounds currently sounding on the specified channel. However, the status of channel messages such as Note On and Hold On is maintained.

● Reset All Controllers (Control #121)

The values of the following controllers will be reset to the defaults: Pitch Bend, Channel Pressure, Sustain

Switch, Modulation, Expression, Portamento, RPN*,

NRPN*, Volume, Pan.

* Number not specified; internal data will not change.

● All Notes Off (Control #123)

Clears all notes currently on for the specified channel.

However, if Sustain Switch or Sostenuto Switch is on, notes will continue sounding until these are turned off.

This message cannot be sent by any CBX-K2 operation; however, when a MIDI error occurs, this message is sent automatically.

● Mono (Control #126)

Performs the same function as when an All Sounds Off message is received, and if the 3rd byte (mono number) is in the range of 0 - 16, sets the corresponding channel to Mono Mode (Mode 4 : m = 1).

● Poly (Control #127)

Performs the same function as when an All Sounds Off message is received, and sets the corresponding channel to Poly Mode (Mode 3).

■ Program Change

Messages which select voices.

■ Channel Aftertouch

The CBX-K2 keyboard does not have aftertouch sensitivity and thus cannot send aftertouch messages by keyboard pressure. However, Channel Aftertouch data can be sent by the Assignable Wheel or Slider. Channel

Aftertouch affects the sound of all notes when it is applied.

■ Polyphonic Aftertouch

The CBX-K2 keyboard does not have aftertouch sensitivity and thus cannot send aftertouch messages by keyboard pressure. However, Polyphonic Aftertouch data can be sent by the Assignable Wheel or Slider.

Polyphonic Aftertouch affects the sound of only the top

About MIDI

note (when several notes are played together) when it is applied.

■ Pitch Bend

Pitch Bend messages are continuous controller messages that allow the pitch of designated notes to be raised or lowered by a specified amount over a specified duration.

SYSTEM MESSAGES

System messages are the data related to the overall system of the device.

■ System Exclusive Messages

System Exclusive messages let you use the CBX-K2 to control various functions on connected devices, including master volume and master tuning, effect type and various other parameters.

● Master Volume

This message controls the volume over all MIDI channels.

F0 7F 7F 04 01 ll mm F7 (Hexadecimal)

* mm(MSB) = appropriate volume value, ll(LSB) = ignored

■ Active Sensing

Once FE (Active Sensing) has been received, if no MIDI data is subsequently received for longer than an interval of approximately 300msec, the CBX-K2 will register an

Active Sensing error.

Refer to the following MIDI Data Format for more information about the various messages.

MIDI Reception

● Merge-related Notes

When Merge is set to ON, MIDI messages received from an external device at MIDI IN can be merged with the data generated by the CBX-K2, and are transmitted as is from

MIDI OUT. However, there are some exceptions, as listed below:

* Active sensing messages <<FE>>, All Note Off messages (<<Bn 7B 00>>) <<F4>> and <<F5>> will not be merged.

* When the CBX-K2 is set to send <<F8>> messages,

<<F8>> messages from an external device will not be merged.

* When the CBX-K2 is not set to send <<F8>> messages,

<<F8>> messages from an external device can be merged.

* When Merge is set to ON, and an <<FE>> message has not been received for over approximately 300 ms, an

Active Sensing error occurs.

* With the exception of System Exclusive data, messages not conforming to the legal byte format will not be merged. System Exclusive data that doesn’t conform to the legal byte format can be merged.

* If during transmission of System Exclusive messages, the messages are cut off or interrupted (for over approximately 400 ms), a MIDI error occurs.

* When Merge is set to on, and RPN/NRPN messages are sent from both the CBX-K2 and an external device connected to MIDI IN, the resulting messages may be mixed and corrupted.

* When Merge is turned off while a key is held, a stuck note results. This is because the CBX-K2 simply turns

Merge off, without changing the Note On status.

During merging of System Exclusive data, all operations from the CBX-K2 are ignored, and <<FE>> and <<F8>> messages from the CBX-K2 will be stopped. This may cause some problems, as listed below:

* Any operations executed from the CBX-K2, in the middle of a System Exclusive message (<<F0- F7>>) sent from an external device, are ignored.

* CBX-K2 operations that start before or end after the

System Exclusive message will be incomplete.

To avoid these problems:

* Turn Merge off or disconnect the MIDI cable (if the

Merge function is not needed).

* Do not operate the CBX-K2 during reception of large

System Exclusive messages, such as bulk dumps.

* When receiving many short System Exclusive messages, operate the CBX-K2 slowly, or avoid operating it at all.

● Response of the CBX-K2 During MIDI Errors

When a MIDI reception error occurs (such as buffer full,

Active Sensing, interruption of System Exclusive, etc.), the

CBX-K2 responds as follows:

1. Merge is set to OFF.

2. Damper Off, All Note Off, All Sound Off messages are transmitted over all channels.

3. The M lamp flashes and the relevant error number appears in the LED display.

To set Merge to ON again, hold down C and press

P.

Troubleshooting

Even though the CBX-K2 is easy to use, it may occasionally not function as you expect it to. If that happens, check the possible problems and solutions below before assuming that the instrument is faulty.

● (Problem)

— (Possible Cause and Solution)

● No sound from the connected device.

— The cables may have been connected incorrectly.

— Controller data, such as Volume, Expression and Master

Volume, may have been set to values too low to produce sound.

— The Fixed Velocity setting may be too low.

● When the power is turned off and on again, the settings you made have been cancelled.

— This is normal. The CBX-K2 has no internal memory backup.

● Sound is cut off.

— When incoming active sensing messages exceed that allowed by the MIDI standard, the sound will automatically be cut off.

● A certain function does not respond or work properly.

— The connected MIDI device may not support the relevant function on the CBX-K2.

● Specific functions/messages cannot be executed or sent properly.

— While holding down C in the middle of an operation, you may have inadvertently released C. Make sure to hold down C for the duration of the operation.

● The connected device does not respond or synchronize to MIDI clock messages, or MIDI clock messages are not sent.

— Make sure that the Tempo setting on the CBX-K2 is set to a value other than oFF. Also make sure that the connected device is set properly for receiving MIDI clock messages. If another device is connected to the MIDI IN of the CBX-K2 and that device is sending the MIDI clock messages, Merge must be set to ON.

● The Tempo cannot be set.

— The Tempo setting is inactive when Tempo is assigned to the

Assignable Wheel or Slider.

● With Merge set to ON, tempo change messages sent from an external device have no effect.

— If an external device is connected to the MIDI IN of the CBX-

K2, and the CBX-K2 is sending its own MIDI clock messages, the MIDI clock messages of the external device will not be sent via MIDI OUT. To have the external device’s clock messages sent, set Tempo on the CBX-K2 to 0.

● Sending a bank select message also sends a program change message.

— This is normal. The CBX-K2 automatically sends the currently set program change number together with a bank select message.

● The RPN or NRPN controller number assigned to the

Assignable Wheel doesn’t function properly.

● The RPN or NRPN direct data send function doesn’t work properly.

About RPN and NRPN

Registered Parameter Numbers (RPN) are controllers that have been added to the MIDI specification and are common among various MIDI devices of different manufacturers. Unlike the Control Change numbers, these use messages composed of three bytes: MSB, LSB and Data Entry.

Non-Registered Parameter Numbers (NRPN) are controllers that have been created by one or more manufacturers, but have not been added to the MIDI specification.

Thus, NRPN functions may be found on some instruments and not others. The NRPN functions of the CBX-

K2 support all XG-compatible devices. Unlike the

Control Change numbers, these use messages composed of three bytes: MSB, LSB and Data Entry.

Other RPN or NRPN messages not provided on the panel can be transmitted using the RPN or NRPN functions in

Group A and B.

Yamaha CBX-K2 Specification

SPECIAL MESSAGE SECTION (U.S.A.)

PLEASE KEEP THIS MANUAL

PRECAUTIONS

PLEASE READ CAREFULLY BEFORE PROCEEDING

WARNING

CAUTION

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-

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.
