Roland FR-4X - Installing Batteries; Turning On the Power

Introduction
The Sections of Your FR-4x
Right Hand Section
This section is normally used for
playing the melody.
The FR-4x’s right hand keyboard is
velocity sensitive.
Right Hand Registers
This section contains the registers for
the right hand and other selectors
Bellows
The movement of the bellows indeed
lends expression and dynamics to the
sound.
Several techniques are available, one of
which is called “bellows shake” (rapid
opening and closing movements).
You can adjust the resistance of the
bellows, and adjust the air button to
specify the inertia of the bellows (the
force required to open and close the
bellows).
Left Hand Registers
This section contains seven registers
for the left hand.
Left Hand Bass and chord section
This section is normally used to play
the accompaniment.
There are two general categories: one
is called “Stradella,” and the other
“Free Bass.”
In Bass & Chord mode, the first two or
three rows of buttons are used to play
bass and the remaining buttons are
used to play chords.
If you select the “Free Bass” system,
the first two rows of buttons are used
to play bass and the remaining buttons
are used to play melodies using the
free bass button layout.
The FR-4x’s bass and chord section is
velocity sensitive.
Air Button
The air button operates a valve that
allows the bellows to open and close
without the accordion making any
sound.
