Page: 16 / 80

Split, transposition functions do not work on the external instrument.
• Is the MIDI OUT set to DELAY OUT? (If it is not set to KEYBOARD OUT, these functions will
not operate.)
• Does the transmission channel of the Disklavier match the reception channel of the external
instrument?
When playing ensemble music, the external instrument receives all parts.
• Is the reception channel of the external instrument set to OMNI ON?
The MIDI OUT CH. was specified, but information is not output through the specified
channel.
• Is the MIDI OUT set to DELAY OUT? (If the performance information transmission channel
was set to KEYBOARD OUT only, you can change to the original channel and transmit.)
Voicing data was dumped from the keyboard or other instrument connected to the MIDI
IN terminal of the Disklavier to the keyboard or instrument connected to the MIDI OUT
terminal of the Disklavier, but on the Disklavier, "MIDI DATA ERROR" is displayed and
the command is not implemented.
• If a large volume of data is transmitted, dump without sending the data via the Disklavier.
You recorded ensemble music yourself, but when you play it back, the rhythm goes
haywire.
• Sometimes if the amount of data is too large, the rhythm goes haywire.
To protect the piano, avoid sending overly large amounts of data. Also, avoid entering quick
repeated not or successive or long scores as much as possible.
The piano repeats the same note over and over.
• Is there a loop in the wiring of the MIDI cable?
Playback is started on the Disklavier, and you wanted to start the rhythm machine and
sequencer simultaneously by using system realtime messages, but cannot start them.
• Timing Clock, Start, Continue, and Stop can be transmitted only in Stop or Recording mode,
when the metronome function is ON.
