Auto Bass Chord (ABC)
The Conventional Full-keyboard ABC mode can be engaged by pressing the
[FULL KEYBOARD] and [SINGLE/FINGERED] buttons simultaneously (both
indicators will light). In this mode the split point is de-activated and notes played any-
where on the keyboard are detected and used to determine the harmonization of the
accompaniment. In the Conventional Full-keyboard ABC mode, chord detection is
possible when at least three notes are played anywhere on the keyboard. The name of
the detected chord will appear on the display.
NOTES
2-note fingerings are not recognized in the Conventional Full-keyboard ABC mode.
If more than 5 notes are played in the Conventional Full-keyboard ABC mode, the
lowest 4 notes are used to specify the chord.

Solo Styleplay will automatically be turned off whenever the Full-keyboard or Conven-
tional Full-keyboard ABC mode is engaged.

Volume Control
The RHYTHM, CHORD 1, CHORD 2, and BASS volume controls can be used to
adjust the volume of the corresponding accompaniment parts when using ABC. In
general, CHORD 1 controls rhythmic chords while CHORD 2 controls more decora-
tive chords (arpeggios, etc.). The volume of the keyboard can be independently con-
trolled by using the BASS volume control while holding the [UTILITY] button.
NOTES
Some styles may not use all four parts: RHYTHM, CHORD 1, CHORD 2, and BASS.

tion” function described on page 64 is turned on. The default setting for this function is
off.
