Some bass and chord buttons
don’t play notes.

No sound is heard when
an external amplifier is
connected.
It may be that the connection cables are broken, or that your amp or speaker has
malfunctioned.
Check the cables and your equipment once again.
—
Did you connect the audio cables to the correct jacks?
Check the connection cables.
—
The volume level of the
instrument is too low when it is
connected to an amplifier.
Could you be using a connection cable that contains a resistor?

The FR-4x does not respond to
your playing.
Did you set the “External Seq. Playback” to “On”?
If this is “O n ,” the FR-4x responds only to MIDI messages that it receives; playing the FR-4x’s
keyboard does not produce sound. Change the setting to “Off” for the appropriate part.

Issues related to the bass
buttons board.
Why do the bass buttons only provide three chord rows?
Because you set the “B&C Mode (Bass & Chord Mode Layout)” to “3 bass rows.”
Set it to “2 Bs Rows.”

Why can’t I play diminished chords using the bass buttons.
Because you set the “B&C Mode (Bass & Chord Mode Layout)” to “3 bass rows.”
Set it to “2 Bs Rows.”
