• A Brief Introduction to MIDI

MIDI, the Musical Instrument Digital Interface, is a world

MIDI Gable

standard communication interface that allows MIDI-compatible

MIDI IN

musical instruments and equipment to share musical information and

control one another. This makes it possible to create "systems" of

1DOu·,·1

MIDI instruments and equipment that offer far greater versatility and

control than is available with isolated instruments. For example,

Clavinova

most MIDI keyboards (including the Clavinova, 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

Data Being Recorded

sequence recording. A sequence recorder can be used to "record"

MIDI data received from a Clavinova, for example. When the

recorded data is played back, the Clavinova automatically "plays"

the recorded performance in precise detail.

The examples given above really only scratch the surface. MIDI

can do much, much more. The Clavinova MIDI functions allow it to

After selecting ",e

or "F

8.':1",

press the [+/YES] button to engage the MIDI function sub

mode, then use the FUNCTION [.,..] and [..-] buttons to select the desired MIDI function, as listed

below.

NOTE

• The rear-panel HOST SELECT switch must be set to "MIDI" in order to use the MIDI connectors. When you use

the TO HOST connector, set the HOST SELECT switch to the appropriate position for the type of computer you

are using (see page

38).

In this situation, a/l MIDI settings described below will have affect on the MIDI signal in

and out of the TO HOST connector .

• Always use a high-quality MIDI cable to connect MIDI OUT to MIDI IN terminals. Never use MIDI cables longer

than about 15 meters, since cables longer than this can pick up noise which can cause data errors.

the instruments or tone generators could be set to receive only on channell, while the other is set to

receive on channel 2. In this situation the first instrument or tone generator will respond only to

channel-l information transmitted by the sequence recorder, while the second instrument or tone
