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.

Guided Tour

When using your CBX-K1 for the first time, read through this short section of the manual. It guides you step-by-step in using many of the basic operations: setting the instrument up, connecting it properly to other equipment, and — most importantly — playing it.

Setting Up Your CBX-K1

In this introductory section, you’ll learn how to set up the CBX-K1 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-K1 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-K1 and an optional PA-3 or PA-1B 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.

With Computer and Tone Generator

In the small MIDI system below, the CBX-K1 is connected to a computer and a single tone generator. With the proper sequencing software on the computer, the CBX-K1 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-K1 to start and stop the sequencer.

With Main Keyboard and Tone Generator

In this system, the CBX-K1 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-K1 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-K1.

NOTE

■

When an external MIDI device is connected to

the MIDI IN of the CBX-K1, the

lamp may flash, indicating a MIDI error. This is probably due to a longer-than-normal interval between active sensing messages received from the device. To remedy this, set the MIDI Merge of the CBX-K1 to ON. (See page 24.)

Making the Connections

■

CAUTION! that all equipment to be connected is turned off.

Operation

Connect the MIDI OUT terminal of the CBX-K1 to the 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

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.)

Finally, turn on the power of the CBX-K1, then turn on

the power of the connected equipment. (If necessary, follow the order as recommended in the owner’s manuals of the devices you are using.) When turning off the power, be sure to turn off the CBX-K1 last.

Before making any connections, make sure

Using the CBX-K1 — Basic Operations

Though the CBX-K1 has many sophisticated functions, it is very easy to use. All available functions can be controlled or executed by using the basic operations described in this section. (For details on individual functions, see pages 18-

22.)

NOTE ■ This introductory section assumes that the MIDI transmit channel of the CBX-K1 and the MIDI receive channel of the connected device match. When the CBX-K1 is turned on, the MIDI transmit channel is automatically set to 1. For the sake of the following sections, set the MIDI receive channel of the connected device to 1 (or Omni).

Playing the Keyboard and Other Operations

The illustration below shows how to use the basic real-time controls of the CBX-K1.

● Changing Voices (Program Change Up/Down)

You can easily step up or down through the voices (program numbers) on the connected MIDI device.

To do this, hold down C and press M (to advance one program number), or press N (to go back one program number). The LEDs quickly flash on and off when a program number message is sent. Release C to play the new voice.

When the CBX-K1 is turned on, the starting point for program change is 0. This means that when you first hold down C and press M, program number 1 will be selected.

NOTE ■ Always release CBX-K1 keyboard. Holding down the secondary or “hidden” functions, and you may inadvertently execute one of these functions by playing the keyboard while continuing to hold down

NOTE

■

This function does not “wrap around.” In other words, you cannot go back to program number 127 when at 0, or advance to program number 0 when at 127.

Using the SHIFT-Related Functions

The enormous flexibility and power of the CBX-K1 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 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.

Basic Operations

Selecting Group A and Group B Functions

● Selecting Group A Functions:

Hold down C and press the appropriate key. (See pages 14 and 18 for specific Group A functions and how to use them.)

● Selecting Group B Functions:

Hold down C and press K. The Group B functions are available as long as you continue to hold down C. (See pages 16 and 20 for specific Group B functions and how to use them.)

Entering Values

Value entry on the CBX-K1 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.

● 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.

* 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.

: results in a value of MSB = 000, 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.

■

NOTE

The order of MSB and LSB entry can be

reversed. (See page 20.)

Example — Setting the MIDI Transmit Channel to 12:

Decimal:

C + { → 1 → 2 → K

Hexadecimal:

C + { → c → J

Value Entry — Some Specific Examples

and Anomalies

● Using K

Examples: * 1 → 2 → K: results in a value of 12. * a → K: results in a value of 10. * 2 → a → K: results in a value of 210. * a → 2 → K: results in a value of 102. * 3 → a → K: results in a value of 310, which is

ignored since it is outside the legal value range (0-255).

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

, the value will be can-

celled.

■

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).

Selecting a Drum Number (when editing a specific drum number with controller

numbers 131 - 141)

You can use operation for editing a specific drum number with controller numbers 131 - 141. 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 (131 through 141). This sets the Controller Number for the Drum parameter you wish to control with the ASSIGNABLE Wheel.

GENERAL

General MIDI (GM)

General MIDI (GM) is a new addition to the worldwide MIDI standard. The main feature of GM is in the standardization of instrument sounds, ensuring that song data recorded in the GM format can be played back on GMcompatible tone generators of any manufacturer, and sound as the composer or programmer intended.

(controller number on panel) *2

Before executing the operation below, use the keyboard to select the desired drum sound (see page 15 ).

C + F → L

XG is a major new enhancement to the GM format developed by Yamaha, and it provides for more instrument sounds and variations, as well as greater expressive control over voices and effects. XG-compatible instruments feature full compatibility with GM, while ensuring forward compatibility with future instruments and software.

Stop command for sequencer/rhythm machine. Continue command for sequencer/rhythm machine. Start command for sequencer/rhythm machine. Tempo entry for sequencer/rhythm machine. Setting this to 0 disables the MIDI clock transmission. When ASSIGNABLE Wheel is set to Tempo (cntrl. no. 148), this is inactive. This allows selection of voice banks on tone generators that support multiple banks. The bank select message must include both MSB and LSB values. This allows entry of program numbers. Stepping up or down through program numbers is also possible by holding down C and using the N / M buttons; see page 10. This resets the connected tone generator to General MIDI operation. WARNING: Be careful when using this, since it automatically changes whatever settings you’ve made on the tone generator. (Only GMcompatible tone generators respond to this message.) This turns all sounds off over the current MIDI channel. To turn all sounds off for all MIDI channels, use All Sound Off in Group B. This resets the connected tone generator to XG operation. WARNING: Be careful when using this, since it automatically changes whatever settings you’ve made on the tone generator. (Only XG-compatible tone generators respond to this message.) When set to ON, this merges all data received at MIDI IN with the data generated by the CBX-K1. Merge can be set independently for each channel in the Group B functions. This determines the MIDI transmit channel for the CBX-K1. This should be set to match the MIDI receive channel of the connected MIDI device.

This sets a fixed velocity value for the keyboard; in other words, playing the keyboard at any strength results in a certain velocity value. When this is set to 0 (initial touch on), Touch Sensitivity can be set in the Group B functions. When ASSIGNABLE Wheel is set to Velocity (147), this is inactive. This determines the RPN (Registered Parameter Number) for the ASSIGNABLE Wheel. This function should be used for all RPN’s not listed on the panel. The message must include both MSB and LSB values. This determines the Controller Number for the ASSIGNABLE Wheel. Though not all are listed on the panel, any of the standard Control Change numbers (0 -119) can be assigned. The RPN, NRPN and Others numbers on the panel can also be assigned here. This determines the NRPN (Non-Registered Parameter Number) for the ASSIGNABLE Wheel. This function should be used for all NRPN’s not listed on the panel. The message must include both MSB and LSB values. This determines the drum number for use with the drum-related controller numbers (131-141).

● 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 CBXK1 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.

This resets all MIDI controller values to their reset values (minimum or center). — — — — This turns all sounds off over all MIDI channels. To turn all sounds off for one specific MIDI channel, use SOUND OFF in Group A. This performs a GM-B reset on a connected tone generator. (This affects only certain tone generators, making their operation compatible with the Yamaha TG300.) — This merges all data received over the selected MIDI channel with the data generated by the CBX-K1. This function can be set independently for each channel. This determines the relative velocity sensitivity of the CBX-K1 keyboard. The lower the Touch Sensitivity value, the higher the output velocity becomes. In other words, when this is set to a value near 0, the less playing strength that is needed to get a louder sound from a connected tone generator. 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.

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.

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.

This determines the Device Number when independently transmitting certain messages (such as XG On and Master Tuning) to more than one connected MIDI devices. This inverts the operation of both Wheels, for ease in playing the CBX-K1 as a hand-held keyboard. An alternate way to change this setting is to simultaneously hold down N and turn on the power. This inverts the MSB/LSB entry (so that LSB precedes MSB). An alternate way to change this setting is to simultaneously hold down M and turn on the power. This sends a data message of a single byte.

Troubleshooting

Even though the CBX-K1 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)

● 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.

● A certain function does not respond or work properly.

— The connected MIDI device may not support the relevant

function on the CBX-K1.

● Incoming data is not merged.

— Make sure that Merge is set to ON. Make sure also that the

Merge on/off function in Group B is set to ON for the relevant MIDI channel.

● Some messages cannot be merged.

— Please refer to the Merge-related Notes in the MIDI Data

Format section, page 24.

● Merge is inadvertently set to OFF.

— When there is some kind of MIDI receive error, Merge is

automatically turned off. Please also refer to the Mergerelated Notes in the MIDI Data Format section, page 24.

● When turning Merge off, the connected tone generator

continues to sound.

— Please refer to the Merge-related Notes in the MIDI Data

Format section, page 24.

● The connected device does not respond to MIDI clock

messages, or MIDI clock messages are not sent.

— Make sure that the Tempo setting on the CBX-K1 is set to a

value other than 0. 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-K1 and that device is sending the MIDI clock messages, Merge must be set to ON.

● 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-

K1, and the CBX-K1 is sending MIDI clock messages, the external device cannot be used to send MIDI clock messages.

● Sending a bank select message also sends a program change

message.

— This is normal. The CBX-K1 automatically sends the

currently set program change number together with a bank select message.

● The RPN or NRPN controller number assigned to the ASSIGN-

ABLE Wheel doesn’t function properly.

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

properly.

— Please refer to the Merge-related Notes in the MIDI Data

Format section, page 24.

● When the power is turned off and on again, the settings you

made have been cancelled.

— This is normal. The CBX-K1 has no internal memory backup.

● Octave Shift function has no effect.

— Octave Shift cannot be changed while a key is being held

down.

● The B lamp flashes, indicating a MIDI error.

— There may be a problem with incoming Active Sensing

messages. (See the Note on page 9.)

— A MIDI device connected to MIDI IN may have been turned

off, or the connecting MIDI cable may have been unplugged or damaged.

— Make sure not to connect a MIDI cable to the MIDI IN while

executing a function on the CBX-K1.

— Too much MIDI data (exceeding the receive capability of the

CBX-K1) may have been received at MIDI IN.

● Instead of both V / B lamps flashing

(indicatiing proper execution of an operation), only the V lamp flashes.

— The battery power is too low for proper operation. Replace all

batteries.

● The keyboard is not touch sensitive.

— Make sure that Fixed Velocity is set to 0.

● The Fixed Velocity setting has no effect.

— Tne Fixed Velocity setting is inactive when Velocity is

assigned to the ASSIGNABLE Wheel.

● The Tempo setting has no effect.

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

ASSIGNABLE Wheel.

● The All Sound Off function has no effect.

— All Sound Off in the Group A functions only applies to the

cureently selected MIDI channel. Also, some tone generators may not respond to the All Sound Off message.

● The rightmost five keys of the keyboard do not sound at the

expected pitch.

— When set to the highest octave range, the rightmost five keys

are set to play notes Gm4 (80) through C5 (84).

● Even when Touch Sensitivity is active, the effective velocity

range is narrower than expected.

— Please refer to Footnote #2 on page 21 for details on velocity

range.

● Some of the keys do not respond to after touch pressure when

playing several notes simultaneously.

— Polyphonic Key Pressure After Touch applies only to the

highest note played.

MIDI Data Format

■ MIDI Reception

● Merge-related Notes

MIDI messages received from an external device at MIDI IN can be merged with the data generated by the CBX-K1, and are transmitted as is from MIDI OUT. However, there are some exceptions, as listed below: * <<F4>>, <<F5>> and any subsequent data bytes will

not be merged.

* All Note Off message (<<Bn 7B 00>>) will not be

merged.

* When the CBX-K1 is set to send <<F8>> messages,

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

* When the CBX-K1 is not set to send <<F8>> messages,

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

merged. * <<FE>> will not be merged. * When Merge is set to ON, and an <<FE>> message has

not been received for over approximately 600 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 ap-

proximately 400 ms), a MIDI error occurs. * When Merge is set to on, and RPN/NRPN messages are

sent from both the CBX-K1 and an external device

connected to MIDI IN, the resulting messages will be

mixed and corrupted. * When Merge is turned off while a key is held, a stuck

note results. This is because the CBX-K1 simply turns

Merge off, without changing the Note On status.

During merging of System Exclusive data, all operations from the CBX-K1 are ignored, and <<FE>> and <<F8>> messages from the CBX-K1 will be stopped. This may cause some problems, as listed below: * Any operations executed from the CBX-K1, in the

middle of a System Exclusive message (<<F0-F7>>)

sent from an external device, are ignored. CBX-K1

operations that start before or end after the System

Exclusive message will be incomplete. To avoid this

problem, be careful not to execute operations from both

the CBX-K1 and the external device at the same time.

Also: * If the Merge function is not needed, turn Merge off or

disconnect the MIDI cable. * Do not operate the CBX-K1 during reception of large

System Exclusive messages, such as bulk dumps.

● Response of the CBX-K1 During MIDI Errors

When a MIDI reception error occurs (such as buffer full, Active Sensing, interruption of System Exclusive, etc.), the CBX-K1 responds as follows:

1. Merge is set to OFF.

2. The MIDI transmit/receive buffer is cleared.

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

4. Transmission of messages (including <<FE>> and <<F8>>) are interrupted for approximately 0.8 seconds. During this time, operations from the CBX-K1 are ignored.

5. The B lamp flashes, indicating a MIDI error.
