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: Assignable 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, compatibility 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 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-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.

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.

NOTE ■ Before making any connections, make sure that all equipment to be connected is turned off.

Using a Power Adaptor

Connect one end of the power adaptor (PA-1D) to the DC IN jack on the rear panel, and the other end to a suitable electrical outlet.

CAUTION! ■ 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 CBXK2, and even pose a serious shock hazard.

■ Be sure to disconnect the power adaptor from the outlet when the CBX-K2 is not in use.

DC IN

STANDBY (?)

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

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

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.

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.
