Using Auto Accompaniment — Multi Fingering
The auto accompaniment function automatically generates bass and chord accom-
paniment for you to play along with, by using Multi Fingering operation. You can
change the chords of the accompaniment by playing keys in the ACMP area 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 Sin-
gle Finger Chords below). The Fingered technique is that of conventionally play-
ing all the notes of the chord. Whichever method you use, the EZ-150
“understands” what chord you indicate and then automatically generates the
accompaniment.

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, Bb7 is played as Bb and A.)

* Notes enclosed in parentheses are optional; the chords will be
recognized without them.
If the chord is inverted (i.e., C-E-G is played
as G-C-E), the EZ-150 will still recognize it
as a C chord. The chord recognition system
also has the following rules and exceptions:
• 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 recog-
nized as the root.
• 7th flatted 5th chords may be played with
the lowest note as the root or the flatted
7th.
• Augmented 7th and diminished 7th
chords are interpreted as simple aug-
mented and diminished.
• The following chords are not recognized :
B minor 6, B
b
minor 6, and B augmented.
