MIDI, the Musical Instrument Digital Interface, is a world-
standard communication 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 versatil-
ity and control than is available with isolated instruments. For
example, 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 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 automati-
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-810S 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 terminals. 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 system allows transmission and reception of MIDI data
on 16 different channels. Multiple channels have been implemented to
allow selective control of certain instruments or devices connected in
series. For example, a single MIDI sequence recorder could be used to
“play” two different instruments or tone generators. One of the
instruments or tone generators could be set to receive only on channel
1, while the other is set to receive on channel 2. In this situation the
first instrument or tone generator will respond only to channel-1
information transmitted by the sequence recorder, while the second
instrument or tone generator will respond only to channel-2 informa-
tion. This allows the sequence recorder to “play” two completely
different parts on the receiving instruments or tone generators.
In any MIDI control setup, the MIDI channels of the transmitting
and receiving equipment must be matched for proper data transfer. An
“ALL” receive mode is also available, which allows reception on all 16
MIDI channels.
