Selecting an Accordion Sound for the Left-
Hand Button Keyboard
The left-hand button keyboard plays bass and chords.
The two rows of buttons enclosed by gray shading play bass, and
the remaining buttons play chords.
Some of the bass rows have reference caps with concave tops
to help you determine the position of the bass and chord rows
without looking at them.
At the factory, these reference caps are installed on the three black
buttons shown in the above illustration, but if you prefer, you can
remove these and reinstall them elsewhere if another location is
more convenient for you.

MEMO
Reed combinations differ slightly for each accordion set.
For the left-hand button keyboard, you can also select a Free Bass
mode for advanced players as an alternative to the standard bass
mode typically used for performing. These two modes each have a
different arrangement of left-hand button keyboard.
& For details on the Free Bass mode, refer to the "Reference
Manual" (PDF).

Adding Depth and Richness to the Sound

[REVERB] knob
This produces acoustic ambience that is reminiscent of a
performance in a concert hall, adding depth to the sound.
Turning the knob toward the right makes the effect stronger. If the
knob is turned all the way to the left, no reverb is applied.
[CHORUS] knob
This produces a sound reminiscent of multiple units of the same
instrument playing in unison.
Turning the knob toward the right makes the effect stronger. If the
knob is turned all the way to the left, no chorus is applied.
Reverb and chorus apply to both the right-hand and left-hand
sounds.
* You can choose the types of reverb and chorus.
& "Reference Manual" (PDF)
NOTE
Depending on the type of sound and the settings, it might be
difficult to detect the result of applying reverb or chorus.
