Follow these steps to start standard fin-
gering auto accompaniment.

1. Set 

 to 

.

2. Select and enter an auto-rhythm.

(See “Selecting/Playing an Auto-
Rhythm” on Page 15.)

3. To start the auto-rhythm before your

auto accompaniment, press 

 or 

.

To synchronize the start of the
selected auto-rhythm with your
accompaniment, press 

.

4. Begin the accompaniment at the

desired interval by pressing at least
three accompaniment keys to play
the desired chord.

To play a melody along with the
accompaniment, press any key(s) to
the right of the accompaniment
keys.

5. To change chords without interrupt-

ing the rhythm, simply press the
auto accompaniment keys required
to form the new chord.

6. To stop accompaniment and the

auto-rhythm, press 

.

While the easy random and standard fin-
gering methods limit chord formations to
the accompaniment keys, the full-range
chord method lets you play chords of
any type using any of the MD-1200’s
keys.

Set 

 to 

 and

follow the steps under “Standard Finger-
ing.” If you press three or more keys
anywhere on the keyboard that form a
chord, the MD-1200 plays that chord.
The MD-1200 responds with melody
sounds if you press fewer than three
keys. 

• In the full-range chord mode, the

MD-1200 recognizes these 23
chords in addition to the 15 chords
in the standard fingering mode
(examples show C as the base
note):

• When the composite notes of a

chord are more than five notes
apart, the lowest sound becomes
the base note.

The MD-1200 lets you set the keyboard
to play an automatic accompaniment
(based on your auto-rhythm selection)
while you play the melody using a tone
you select. Refer to the “Free Session
Chord Progression Chart” on Page 54
for the chord progression, tempo, and
tone associated with each auto-rhythm.
