About Multi Fingering

The Auto Accompaniment function automatically generates 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.
Though detection of the Single Finger and Fingered methods is automatic with Multi Fingering, you can set Auto
Accompaniment to function exclusively in either the Single Finger or Fingered mode.
To set Auto Accompaniment to Single Finger:
Turn the power off, then hold down the "-" key on the numeric keypad and simultaneously turn the power on. ("SINGLE"
briefly appears in the display.)
To set Auto Accompaniment to Fingered:
Follow the same steps as above, holding down the "+" key instead. ("FINGERED" briefly appears in the display.) To switch
back to Multi Fingering operation, simply turn the power off and on again.
Single Finger Chords
Chords that can be produced in Single Finger operation are major, minor, seventh and minor seventh. The illustration below
shows how to produce the four chord types. (The key of C is used here as an example; other keys follow the same rules. For
example, B 7 is played as B

• If the chord is inverted (i.e., C-E-G is played as G-C-E), the PortaTone will
still recognize it as a C chord.
• Minor 6th chords are recognized only in root position, however; all other
inversions are interpreted as minor 7th/flatted 5th.
• If augmented and diminished 7th chords are inverted, the lowest note will
be recognized as the root.
• 7th flatted 5th chords may be played with the lowest note as the root or
the 7th.
