MIDI Troubleshooting and Know-how
When MIDI Is connected, there are a few mistakes and problems that occur frequently.
A sound source instrument has been connected to the MIDI OUT terminal, but no sound
is produced by the external instrument.
• Are you sure the MIDI cable is firmly connected between the MIDI OUT terminal of the
Disklavier and the MIDI IN of the external instrument?
• Does the reception channel of the external instrument match the transmission channel of
the Disklavier?
• If you are performing, is the MIDI OUT switched to KEYBOARD OUT?
• During playback, is the MIDI OUT switched to DELAY OUT? (In this case, the transmission
channel of the Disklavier cannot be changed.) Or, if it is KEYBOARD OUT, is the volume
setting of the MIDI OUT VOL. or the piano volume too low?
A keyboard or sequencer is connected to the MIDI IN terminal, and performance took
place on the external instrument, but the piano keys were not struck.
• Is the MIDI cable firmly connected between the MIDI OUT terminal of the external instrument
and the MIDI IN of the Disklavier?
• Is the power on, and has a floppy disk been inserted?
• Does the reception channel of the Disklavier match the transmission channel of the external
instrument?
• Is the volume setting of the piano (MIDI IN VOL.) too low?
A keyboard or sequencer is connected to the MIDI IN terminal of the Disklavier, and
performance took place on the external instrument, but the piano keys were struck
with delay.
• It takes about 0.5 seconds from the time the information is received until the time the piano
keys are struck.
There is a difference in pitch between the piano and the external instrument.
• Is the transposition function on?
• Is the TRANS/BEAT set to something other than "normal"?
The voicing of the external instrument can not be changed.
• Does the transmission channel of the Disklavier match the reception signal of the external
instrument? (If they do not match, the voicing cannot be changed.)
The MIDI OUT VOL. function does not operate for the external instrument.
• Does the transmission channel of the Disklavier match the reception channel of the external
instrument? (If they do not match, switching is not possible.)
During performance or playback on the piano, there is no problem with the piano, but
the upper or lower tones are not produced on another keyboard.
• Are you playing music separated for left and right hand?
• Is the split function on?
