Using the Auto Accompaniment
Function/Multi Fingering
The Auto Accompaniment function automatically gener-
ates bass and chord accompaniment for you to play along
with, by using Multi Fingering operation. You can change
the chords of the accompaniment by playing keys in the
AUTO ACCOMP. SECTION of the keyboard using either the
“Single Finger” or “Fingered” method. With Single
Finger you can simply play a one-, two- or three-finger
chord indication (see Single Finger Chords below). The
Fingered technique is that of conventionally playing all the
notes of the chord. Whichever method you use, the
PortaTone “understands” what chord you indicate and
then automatically generates the accompaniment,
