How to Replace a Right Hand Button of Your FR-4xb Keyboard
Since your FR-4x is an electronic musical instrument, changing the
note assignments to the buttons is a matter of selecting the preset
that best suits your playing style. You’ll probably only change this
setting once. But it’s nice to know that it exists in case you let a
fellow accordion player from another country play your FR-4x.
Please look at the illustrations on pages “TrblMode (Treble Mode
Layout)” (p. 74) and p. 102–p. 103 to identify the setting you
need. Pay attention to the note names (all Cs appear on a gray
background) and look at how they are arranged, then make your
selection. The numbers next to the letters refer to the octave. The
numbers below the note names represent the corresponding MIDI
note numbers.
You may have noticed that the treble buttons are colored white (for
notes without alteration) and black (notes with alteration, i.e.
¾
/
²
).
This coloring doesn’t change when you select another system.
The FR-4x is supplied with additional white and black buttons.
You can use these additional buttons to adapt the black and white
treble buttons to reflect the selected treble mode.
To do this, first remove the button you wish to replace by turning
it counterclockwise, then install the new button and screw it
clockwise.
WARNING
Take care do not force to tighten the treble
button (tighten with a torque 0.3 Nm max).
Tightening this excessively might strip the
button’s screw threads.
If you remove the treble button from the
button keyboard, be sure to replace it; don’t
leave them lying around where it could
accidently be swallowed by small children.
Bass & Chord Button Board
The FR-4x is supplied with several reference caps (concave and
with lines) designed to help you locate the bass and chord buttons
without looking at them. At the factory, three caps are installed on
the buttons shown in the illustration below. Feel free to remove
them and to slide them over other buttons if that feels more
comfortable.
