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

1.Set MODE to FINGERED.

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 START/ STOP or INTRO.

To synchronize the start of the selected auto-rhythm with your accompaniment, press SYNCHRO/ ENDING.

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 START/STOP.

Set MODE to FULL RANGE CHORD 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-1600 plays that chord. The MD-1600 responds with melody sounds if you press fewer than three keys.

Notes:

•In the full-range chord mode, the MD-1600 recognizes these 23 chords in addition to the 15 chords in the standard fingering mode (examples show C as the base note):

C6	Cm6	C6/9	C/C	D/C	E/C
F/C	G/C	A/C	B/C	BCm/	Dm/C
				C
Fm/C	Gm/C	Am/C	Bm/C	Dm7-	C
				5/
A7/C	F7/C	Fm7/	Gm7/	Aadd9/C
		C	C

•When the composite notes of a chord are more than five notes apart, the lowest sound becomes the base note.

Full-Range Chords

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 on any of the MD-1600’s keys.

Using FREE SESSION

The MD-1600 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.
