When the accompaniment mode is set to NORMAL during
step recording, you can specify chords using a method that is
different from CASIO CHORD and FINGERED fingerings.
This chord specification method can be used to input 18
different chord types using only two keyboard keys, so
chords can be specified even if you don’t know how to
actually play them.
To specify a chord, hold down the key on the root input
keyboard that specifies the root, and press the key in the
chord type input keyboard to specify the chord type. When
inputting a chord with a specified bass note, pressing two
keys of the root input keyboard causes the lower note to be
specified as a bass note.
Example 1:
To input Gm7, hold down G on the root input
keyboard and press the m7 key on the chord
type input keyboard.
