Adjusting the Sensitivity of the Bellows
Like acoustic accordions, the FR-4x/FR-4xb produce sound when
you use your left hand to open and close (expand and contract) the
bellows. In general, sound is not produced unless you move the
bellows.
On the FR-4x/FR-4xb, you can adjust the sensitivity of the bellows
to your preference.
To adjust the sensitivity of the bellows, you’ll use the bellows
resistance regulator located at the side of the left-hand bellows
strap, and a setting within the FR-4x (bellows curve).
1.
Use the bellows resistance regulator to adjust the
resistance of the bellows to being opened or closed.
Turning the bellows resistance regulator changes the resistance
when opening or closing the bellows.

Next, change the internal setting (bellows curve) as follows.
2.
Hold down the [SHIFT] button and press the right-
hand register [7/14] button.
The following screen appears.
3.
Use the VALUE [-] [+] buttons to change the value.
Value Explanation
FIX.L (Fixed Low)
FIX.M (Fixed Med)
FIX.H (Fixed High)
The volume is fixed, regardless of bellows
movement. This is convenient when you
want to play without moving the bellows.
“Fixed Low” is a low volume, “Fixed High”
is a high volume, and “Fixed Med” is an
intermediate volume.
X-LT (X-Light)
Adequate volume change can be
obtained by moving the bellows even
more gently than the “Light” setting.
LIGT (Light)
Volume change can be obtained even by
moving the bellows gently. This setting
allows easy playing when the bellows
resistance regulator is set to a light setting.
STD (Standard)
This is the standard setting. This setting
allows easy playing when the bellows
resistance regulator is set to a medium
setting.
Value Explanation
HEVY (Heavy)
Although the bellows must be moved
strongly to obtain volume change, this
setting allows a broad range of nuances to
be added. This setting allows easy playing
when the bellows resistance regulator is
set to a heavy setting.
X-HV (X-Heavy)
This setting requires the bellows to be
moved even more strongly than the
“Heavy” setting.

Press the [EXIT] button to return to the previous
screen.
MEMO
The bellows curve setting is automatically saved when you turn
off the power.
Air button
Pressing the air button lets you open or close the bellows quickly.
Use this if the bellows are open when you’ve finished playing.
Adjusting the Volume
To change the volume, turn the [VOLUME] knob located at the
right-hand keyboard side.
Turn the knob toward the right to increase the volume, or toward
the left to decrease it.
Adjusting the Balance
Turn the [BALANCE] knob to change the volume balance between
the right-hand keyboard (TREBLE) and the left-hand button
keyboard (BASS).
Normally, you’ll leave this in the center.
