16. Troubleshooting
This section provides an overview of points to check and actions to take when the FR-3x 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).
No sound is heard when an external amplifier is
connected
■Did you switch on the connected amplifier?
Please check this.
■ Did you connect the audio cables to the correct
sockets?
If so, check the cables for possible damage.
No sound when you play on the treble keyboard
You may have muted the Treble section. See “Switch-
ing off the treble section” on p. 27 for how to acti-
vate it again.
No sound when you play on the bass keyboard
You may have muted the Bass/Chord section. See
“Switching off the Bass and/or Chord section” on
p. 31 for how to activate it again.
No sound and the display shows “---”
■Did you set the “MId” parameter to “In”?
In that case, the FR-3x only responds to MIDI mes-
sages. Set the parameter to “Out” (page 58).
No power
■Did you disconnect the adapter?
Connect the supplied adapter, or install optional bat-
teries.
■Did the FR-3x go off after several seconds?
The “Auto Power Off” function may be active. Set it to
“Off” (page 55).
The FR-3x does not respond to your playing
■Did you set the “MId” parameter to “In”?
In that case, the FR-3x only responds to MIDI mes-
sages. Set the parameter to “Out” (page 58).
■ 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 53). 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 53). 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 51).
MIDI-related issues
■What MIDI channels does the FR-3x use by
default?
See the table on page 56.
■ The FR-3x does not change sounds when my
sequencer transmits program change numbers.
The program change number probably outside the
range of the FR-3x’s registers (see “Program change
messages” on p. 71). Such “excess” program numbers
are ignored by the FR-3x.
■ The FR-3x 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 58).
■ 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. 62.
Other issues
■Can’t read the/write to USB memory
Are you using a USB memory made by another man-
ufacturer than Roland?
