10. Troubleshooting
This section provides an overview of points to check and actions to take when the FR-3 does not function as you expect.
Feel free to contact your Roland dealer if your issue remains unsolved after reading through this section.

No sound

■Did you turn the [VOL] knob all the way to the
small dot?
Set it to a higher value.
■Did you turn the [BAL] knob all the way to one
side?
Change its setting and try again.
■Are you moving the bellows while triggering
accordion sounds?
The Treble and Bass/Free Bass sections only produce
sound if you move the bellows while playing notes
(like on an acoustic accordion).
■Did you connect the FR-3/FR-3b to an external
amplifier?
The FR-3/FR-3b doesn’t contain internal speakers and
therefore needs to be connected to an external
amplification system. Alternatively, you can use a
pair of headphones.
■Did you connect the audio cables to the correct
sockets?
If so, check whether the external amplifier, mixing
console, etc., is switched on. Also check the cables for
possible damage.

No sound and the display shows “---”

■Did you set the “MId” parameter to “In”?
In that case, the FR-3 only responds to MIDI mes-
sages. Set the parameter to “Out” (page 50).

No power

■Did you disconnect the adapter?
Connect the supplied adapter, or install optional bat-
teries.
■Did you remove the battery cover?
For your safety, the power is automatically switched
off within a few seconds after the battery cover is
removed.
■Did the FR-3 go off after several seconds?
You probably did not install the battery cover all the
way, which is why the power was automatically
switched off.

The FR-3 does not respond to your playing

■Did you set the “MId” parameter to “In”?
In that case, the FR-3 only responds to MIDI mes-
sages. Set the parameter to “Out” (page 50).
■Are you moving the bellows while triggering
accordion sounds?
The Treble and Bass/Free Bass sections only produce
sound if you move the bellows while playing notes
(like on an acoustic accordion).

Issues related to the bass buttons

■Why do the bass buttons only provide three
chord rows?
Because you set the “Bass & Chord Mode” parameter
to “2”, “3”, “4” or “5” (page 45). Set it to “1”.
■Why can’t I play diminished chords using the
bass buttons?
Because you set the “Bass & Chord Mode” parameter
to “2”, “3”, “4” or “5” (page 45). Set it to “1”.
■In Free Bass mode, the bass buttons play the
wrong notes.
You my have changed the “Free Bass Mode” setting.
Be sure to select the system that best suits your play-
ing style (page 43).

MIDI-related issues

■What MIDI channels does the FR-3 use by
default?
See the table on page 47.
■The FR-3 does not change sounds when my
sequencer transmits program change numbers.
The program change number probably outside the
range of the FR-3’s registers (1~10 for Treble, 1~7 for
Bass/Free Bass/Orch. Bass/Orch Chord/Orch Free Bass,
1~10 for Orchestra). Such “excess” program numbers
are ignored by the FR-3.
■The FR-3 does not receive the MIDI messages I
recorded for it.
That’s because the “MId” parameter is currently set to
“Out”. Set it to “In” (page 50).
■All of the FR-3’s settings have changed.
You probably transmitted a “Bulk” file. The settings of
that file have replaced your own settings. We regret
that your settings cannot be restored. Be sure to
archive the internal settings before transmitting bulk
data to the FR-3 (page 54).
■The external sequencer keeps displaying a “MIDI
Buffer Overflow” message
The bellows sends too many data at once (its data are
transmitted on five channels simultaneously). Select
a different setting (“2” or “1”). This leads to a coarser
resolution, and maybe to audible steps, but at least,
your sequencer will be able to record the data. See
“Bellows TX Resolution” on p. 52.
