MIDI channels

MIDI performance data is assigned to one of sixteen
MIDI channels. Using these channels, 1 - 16, the
performance data for sixteen different instrument parts
can be simultaneously sent over one MIDI cable.
Think of the MIDI channels as TV channels. Each TV
station transmits its broadcasts over a specific
channel.Your home TV set receives many different
programs simultaneously from several TV stations and
you select the appropriate channel to watch the desired
program.

MIDI operates on the same basic principle. The
transmitting instrument sends MIDI data on a specific
MIDI channel (MIDI Transmit Channel) via a single
MIDI cable to the receiving instrument. If the receiving
instrument's MIDI channel (MIDI Receive Channel)
matches the Transmit Channel, the receiving instrument
will sound according to the data sent by the
transmitting instrument.

The Clavinova's keyboard and internal tone generator are also
connected by MIDI (page 145).
For example, several tracks (channels) can be
transmitted simultaneously, including the style data (as
shown below).
Example: Recording the auto accompaniment of the Clavinova to
an external sequencer

As you can see, it is essential to determine which data
is to be sent over which MIDI channel when
transmitting MIDI data (page 146). The Clavinova also
allows you to determine how the received data is
played back. (page 147).

■ System Messages

This is data that is used in common by the entire MIDI
system. System messages include messages like Exclusive
Messages that transmit data unique to each instrument
manufacturer and Realtime Messages that control the
MIDI device.
Message Name CVP-900 Operation/Panel Setting
System Exclusive Effect type settings (Mixing Console),
Message etc.
Realtime Messages Clock setting, Start/stop operation
The messages transmitted/received by the CVP-900 are
shown in the MIDI Data Format and MIDI
Implementation Chart in the separate Data List.

What You Can Do With MIDI

The following MIDI settings can be made on the
Clavinova:
• MIDI templates (preset MIDI setups for various
applications) (page 145)
• Transmit (page 146)
• Receive (page 147)
• Local Control (page 145)
• Clock (page 146)
■
Record performance data (1-16 channels) using the
CVP-900 Auto Accompaniment features on a external
sequencer (such as a personal computer). After
recording, edit the data with the sequencer, then play
it again on the CVP-900 (playback).
