MIDI "Messages" Transmitted

& Received by the Clavinova

Note and Velocity Data

This information tells the receiving keyboard or tone generator to play a certain note (specified by the MIDI

note number) at a certain dynamic level (specified by the MIDI velocity value). Note and velocity data is trans-

mitted by the Clavinova whenever a key is pressed, and the Clavinova's internal AWM tone generator will

"play" the corresponding note(s) whenever note and velocity data is received from an external MIDI device.

Program Change Numbers

The CLP-123 transmits a MIDI program change number between 0 and 8 when one of its voice selectors is

pressed. This normally causes the correspondingly numbered voice to be selected on a receiving MIDI device.

The Clavinova will respond in the same way, automatically selecting the appropriate voice when a MIDI pro-

gram change number is received. See "Program Change ON/OFF" on page 16 for information on turning pro-

gram change number reception and transmission ON or OFF.

Control Change Numbers

Control Change data representing Soft, Sostenuto and Damper pedal operations is transmitted by the

Clavinova whenever one of these pedals is used. If the receiving device is a tone generator or another keyboard,

it will respond in the same way as the Clavinova's internal tone generator when one of the pedals is used. The

Clavinova also receives and responds to the appropriate control change data. See "Control Change ON/OFF" on

page 17 for information on turning control change number reception and transmission ON or OFF.

MIDI, the Musical Instrument Digital Interface, is a world-standard com-

munication interface that allows MIDI-compatible musical instruments and

equipment to share musical information and control one another. This

makes it possible to create "systems" of MIDI instruments and equipment

that offer far greater versatility and control than is available with isolated

MIDI IN

instruments. For example, most MIDI keyboards (including the Clavinova,

DOM-30

of course) transmit note and velocity (touch response) information via the

MIDI OUT connector whenever a note is played on the keyboard. If the

MIDI OUT connector is connected to the MIDI IN connector of a second

keyboard (synthesizer, etc.) or a tone generator (essentially a synthesizer

with no keyboard), the second keyboard or tone generator will respond

precisely to notes played on the original transmitting keyboard. The result is

that you can effectively play two instruments at once, providing thick multi-

instrument sounds.

This same type of musical information transfer is used for MIDI se-

quence recording. A sequence recorder such as the Yamaha DRC-20 Disk

Recorder can be used to "record" MIDI data received from a Clavinova, for

MIDI OUT

MIDI IN

example. When the recorded data is played back, the Clavinova automati-

DRC-20

cally "plays" the recorded performance in precise detail.

The examples given above really only scratch the surface. MIDI can do

much, much more. The CLP-123 offers a number of MIDI functions that

allows it to be used in fairly sophisticated MIDI systems.

Note: Always use a high-quality MIDI cable to connect MIDI OUT to MIDI IN termi-

nals. Never use MIDI cables longer than about 15 feet, since cables longer than

this can pick up noise which can cause data errors.

The MIDI information (messages) transmitted and received by the

Clavinova are as follows:
