V-Accordion FR-18 diatonic
Troubleshooting
This section provides an overview of points to check and
actions to take when the FR-18 diatonic does not func-
tion 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 [VOLUME] knob all the way to
the small dot?
Set it to a higher value.
■ Did you set the balance all the way to one sec-
tion?
Change this setting and try again. See “How to bal-
ance the various sections” on p. 31 and “Treble/
Bass&Chord Balance” on p. 43.
■ Are you moving the bellows while triggering
accordion sounds?
The Treble and Bass & Chord sections only produce
sound if you move the bellows while playing notes
(like on an acoustic diatonic 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 cor-
rect sockets?
If so, check the cables for possible damage.
The bellows exhibits an erratic behavior
If the bellows doesn’t work as expected, causing
notes to sound even while it is not moved, its sensors
may need resetting.
To do so, switch off the FR-18 diatonic, then press
and hold the [ORCH.BASS] and [TABLATURE/INC] but-
tons while switching the FR-18 diatonic back on. If
this operation doesn’t solve the problem, contact
your Roland dealer.
The button keyboards play the wrong notes
You may have selected the wrong tablature setting or
the wrong key. See “Selecting a tablature with its
original key” on p. 33.
Alternatively, you may have loaded different tabla-
ture settings and are now using one of those (see
p. 39). Please check the file in question on your com-
puter.
No sound when you play on a button keyboard
You may have muted the section in question. See
“Switching off sections you don’t need (Mute func-
tion)” on p. 30 for how to activate it again.
No power
■Did you disconnect the adapter?
Connect the supplied adapter, or install commercially
available batteries.
■Did the FR-18 diatonic go off after several sec-
onds?
The “Auto Power Off” function may be active. Set it to
“Off” (page 46).
The FR-18 diatonic does not respond to your
playing
■Did you set the “MIDI OUT/IN” parameter to “In”?
In that case, the FR-18 diatonic only responds to
MIDI messages. Set the parameter to “Out” (page 50).
■ Are you moving the bellows while triggering
accordion sounds?
The Treble and Bass sections only produce sound if
you move the bellows while playing notes (like on an
acoustic diatonic accordion).
Issues related to the bass buttons
■Why do some bass buttons trigger chords?
Because you changed the assignments by selecting a
different tablature (see p. 33).
■ Why are the chords played with the chord but-
tons incomplete?
Because you selected the behavior where the third is
omitted. Select full chord mode (see p. 28).
MIDI-related issues
■What MIDI channels does the FR-18 diatonic use
by default?
See the table on page 47.
■ The FR-18 diatonic does not change sounds
when my sequencer transmits program change
numbers.
The program change number probably lies outside
the range of the FR-18 diatonic’s registers (see “Pro-
gram Change numbers” on p. 64). Such “excess” pro-
gram numbers are ignored by the FR-18 diatonic.
■ The FR-18 diatonic does not receive the MIDI
messages I recorded for it.
That’s because the “MIDI OUT/IN” parameter is cur-
rently set to “Out”. Set it to “In” (page 50).
■ 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). You
may be able to solve the problem by setting the “Bel-
lows Expression TX” parameter (see p. 49) to “Right
hand” or “Left hand”, depending on which section
needs to transmit expression messages for the bel-
lows.
Other issues
■Can’t read the/write to USB memory
Are you using a USB memory made by another man-
ufacturer than Roland?
