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.
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.

Each time the power is turned on, the CBX-K2 returns to the default condition. (See boxed section on page 10.) This is for connection to the MIDI IN terminal of another MIDI device (such as a MIDI tone generator, sequencer or computer that has a MIDI interface), for sending MIDI messages to that device.
Guided Tour 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.
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.
Setting Up Your CBX-K2 For tone generators without a built-in MIDI interface With Sequencer The CBX-K2 can be used with a stand-alone sequencer, for recording and editing performance data. CBX-K2 MIDI OUT CBX-K2 MIDI OUT MIDI OUT MIDI IN MIDI Interface MIDI IN MIDI IN Tone generator Serial port Sequencer Connect the MIDI OUT terminal on the CBX-K2 to the MIDI IN terminal on the sequencer.
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.
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.
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. 2. While continuing to hold down C, enter the number 64 (press 6, then 4), then press K. Operation 1. Simultaneously hold down C and press T.
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 pitch up. The Pitch Bend Wheel is spring-loaded for returning to center (normal pitch).
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.
Reference Using the SHIFT-Related Functions 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.
Using the SHIFT-Related Functions 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.

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.
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.
About MIDI ● All Notes Off (Control #123) Clears all notes currently on for the specified channel. note (when several notes are played together) when it is applied. However, if Sustain Switch or Sostenuto Switch is on, notes will continue sounding until these are turned off. ■ 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.
MIDI Data Format 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 <>, All Note Off messages (<>) <> and <> will not be merged. * When the CBX-K2 is set to send <> messages, <> messages from an external device will not be merged.
MIDI Data Format 2. Overview Transmitted data includes messages from the CBX-K2 itself and messages from an external device connected to MIDI IN. Besides conventional MIDI messages, single byte data can also be transmitted. 3. Transmitted Data <<9n kk vv>> 0-15 0-127 0 : note off, 1-127 : note on (2) Polyphonic key pressure <> n=Channel 0-15 kk=Note number 0-127 vv=Pressure value 0-127 * When pressing several keys simultaneously, after touch of only the highest note number is output.
