FR-7x V-Accordion
This section provides an overview of points to check and actions to take when the FR-7x does not function as you expect.
Feel free to contact your Roland dealer if your issue remains unsolved after reading through this section.
The screen is difficult or impossible to read
If you have trouble reading the information in the
display, change the “10.1 LCD Contrast” setting
(page 86).
No sound
■Did you turn the [VOLUME] knob all the way to
the small dot?
Set it to a higher value.
■ Did you turn the [BALANCE] 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 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 power
■Did you remove the supplied battery pack?
Be sure to install it again. Alternatively, connect the
FR-7x to the supplied FBC-7.
■ Did you install the cover of the FR-7x’s battery
compartment?
You need to install it before you can switch on the
FR-7x (page 16). Be sure to tighten the screws all the
way.
The FR-7x does not respond to your playing
■You may have selected “Ext. Seq. Playback” mode
for one or all sections.
Those sections therefore only respond to MIDI mes-
sages received from other instruments. Switch off
the “Ext. Seq. Playback” function (page 109).
The chord rows of the bass keyboard don’t play
accordion sounds
■You probably switched on the ORCHESTRA
CHORD section.
Switch it off (see p. 19).
Certain parameters cannot be selected
■Does the FR-7x display a message to inform you
that a parameter or section is not available?
If so, the section is off, which is why its parameters
cannot be edited. Switch the section on and try
again.
One section sounds off (flat)
Did you set “1.5 Scale Assign” to just one section? Set
it to “ALL” and try again (page 65).
Issues related to the bass buttons
■When I play bass notes and/or chords, I also hear
drum sounds. How do I switch them off?
See “3.7 Bass Drum” on p. 72 and “3.8 Chord Drum”
on p. 73.
■Some bass and chord buttons don’t play notes
Did you activate the “10.6 Function Switch” parame-
ter (page 88)? If so, switch it off.
■Why do the bass buttons only provide three
chord rows?
Because you set the “10.8 Bass&Chd Mode” parame-
ter to “3 Bs Rows” (page 89). Set it to “2 Bs Rows”.
■ Why can’t I play diminished chords using the
bass buttons?
Because you set the “Bass&Chd Mode” parameter to
“3 Bs Rows” (page 89). Set it to “2 Bs Rows”.
■ In Free Bass mode, the bass buttons play the
wrong notes.
You may have changed the “Free Bass Mode” setting.
Be sure to select the system that best suits your play-
ing style (page 90).
■ In Free Bass mode, only half the buttons play
notes.
That’s because the “STATUS” entry of the
“4.2 Register” parameter uses the same (“High” or
“Low”) setting for both reeds (or “Off” for one of
them and “High”/“Low” for the other). Choose com-
plementary settings (“High” for one, “Low” for the
other) or set at least one to “Whole” (page 74).
All my changes have gone
■The FR-7x only remembers the changes you
make until you switch it off or until it is
switched off by the “10.12 Auto Power Off”
function (page 92).
Those changes are lost and cannot be restored. Next
time Try to save your changes as quickly as possible.
