Auto Bass Chord
1 Mode: Off, Single, Fingered, Custom
Off
Cancels the Auto Bass Chord function.
Single (Single Finger mode)
The Single Finger mode provides the fastest and easiest means to obtain
many different chord/bass combinations, by simply using one, or at most,
two or three fingers to play the chords.
Refer to the chart below, Chords Recognized in the Single Finger Mode,
for details on playing chords in this mode.
Fingered (Fingered Chord mode)
The Fingered Chord mode automatically produces bass and chord
accompaniment for chords played in the Lower keyboard. It allows you to
use a wider range of chord types than in the Single Finger mode. In the
Fingered Chord mode, you play all the notes of the chord while the Auto
Bass Chord function automatically selects the appropriate bass pattern and
rhythmic accents.
Refer to the chart below, Chords Recognized in the Fingered Chord Mode,
for details on playing chords in this mode.
Custom (Custom A.B.C. mode)
The Custom A.B.C. mode is a slight variation on the Fingered Chord
mode. It allows you to determine what bass notes will be played in the
accompaniment by playing a note on the Pedalboard along with the
chords you play in the Lower keyboard.
2 Memory
The Memory function allows you to have the bass and chord
accompaniment continue even after you release your fingers from the
keyboard. Independent Memory settings are available for the Lower
keyboard and Pedalboard, making it possible, for example, to have the bass
continue with the rhythm while the chord accompaniment "rests." The
Memory function can also be used independently from the A.B.C. feature.
The bottom right Data Control button pair is used to control the Memory
function. The left button corresponds to the Lower keyboard, and the
right button corresponds to the Pedalboard.
L (Lower)
When Lower is set to on (solid box), the chord accompaniment of the
Lower Keyboard voices continues to play even after you release your
fingers from the Lower keyboard.
P (Pedal)
When Pedal is set to on (solid box), the bass accompaniment of the
Pedalboard voices continues to play even after you release your fingers
from the Lower keyboard.
The Auto Bass Chord function
can also be selected from the
NOTE
A.B.C./ M.O.C. page. To select
the A.B.C./ M.O.C. page, press the
A.B.C./ M.O.C. button in the DISPLAY
SELECT section.
