Troubleshooting
If your system is not operating as you think it should be, first check
the following points. If after checking these points the
problem persists, consult your dealer or local Roland Service Station.
* If any sort of message is being displayed on the screen during an
operation, refer to
“Error Messages/Messages”
(p. 105).
No power
Is the AC Adapter plugged into the power
socket correctly?
No sound
Is the power for the connected amp and
speakers turned on? (p. 15)
Is the volume turned down?
Check the volume settings for the JUNO-D and any connected
amp or mixer (p. 15).
Are the components properly connected? (p. 14)
If you are able to hear sound through headphones, this may
suggest a short in a cable or a malfunctioning amp or mixer.
Recheck connector cables and the connected equipment.
If you are in Performance mode, have the Part
Level settings been lowered? (p. 56)
Have you switched the JUNO-D mode to that
for listening to demo songs?
Press [EXIT] to return to regular performance mode (p. 18).
Is [SOLO SYNTH] set to ON?
The JUNO-D does not sound if you just switch [SOLO SYNTH]
on. Hold down keys, then move your hand over the D Beam (p.
32).
Are the effects settings correct?
Check effects ON/OFF (p. 65), multi-effects levels (p. 46, p. 56),
and other related settings.
Has the pitch of the patch exceeded the range
in which it can be sounded normally?
Use “Octave Shift” to lower (raise) the range being played (p.
30).
If no sound is produced when you press keys
on the keyboard, is Local control set to OFF?
Set Local Control to ON (p. 89).
Do the transmission and reception channels match?
• If using the JUNO-D to sound an external MIDI sound generator,
check to make sure the channels being used for transmission by
the keyboard are matched up with the channels used for
reception by the relevant Parts on the external MIDI sound
generator (p. 93).
• If using an external MIDI device to sound the JUNO-D, each
Part’s reception channel needs to be set so it matches the
channels that will be used for transmission by the external MIDI
device (p. 94).
Are volume levels being lowered by pedal
movements, or by MIDI messages (expression
messages) received from an external MIDI
device?
Is the MIDI Rx (Receive) Switch of the
corresponding part set to “OFF”?
If using the JUNO-D with an external MIDI device, turn it “ON”
(p. 95).
Could the Bank Select and Program Change
messages transmitted by an external device
have the wrong values?
If using the JUNO-D with an external MIDI device, make sure
that the correct Bank Select and Program Change messages (p.
95) are transmitted.
Is the Clock Source set to MIDI?
If you set the clock source to “MIDI,” some of the effects that are
synchronized with the tempo will not work. Set the clock source
to “INT” except when you want to synchronize the JUNO-D
with an external MIDI device (p. 89).
The pitch is off
Could Transpose be on? (p. 31)
Are the Octave Shift settings correct? (p. 30)
Are the Scale Tune settings correct? (p. 91, p.
58)
Are the Master Key Shift settings correct? (p.
89)
Are the Master Tune settings correct? (p. 89)
Sounds are missing
Could a Solo switch be set to ON?
When a Solo switch (p. 46) is on, only one sound is played even
when more than one key is pressed. If you want multiple sounds
to play simultaneously, set the Solo switch to OFF.
Are you attempting to play more than 64
voices simultaneously?
• Reduce the number of notes that are played simultaneously.
• Set Voice Reserve higher for an important Part, to help assure
that it will always be sounded (p. 56).
