17
To start a rhythm with an introduction,
select and enter the rhythm, then press
INTRO . The introduction plays, then the
selected auto-rhythm automatically
starts.
Using FILL-IN
The FILL-IN feature lets you insert a
short (1- to 2-measure) fill-in segment
into a selected auto-rhythm.
To insert the fill-in segment, press and
release
NORMAL/FILL-IN while the auto-
rhythm is playing. The MD-1600 inserts
a 1- to 2-measure variation in the
rhythm, then the original rhythm auto-
matically resumes.
Using VARIATION
Each of the MD-1600’s 100 preset auto-
rhythms has a built-in variation (alter-
nate) to its normal beat pattern. The
variation differs slightly from the normal
rhythm, so it is almost like having two
rhythms in one!
To play the alternate rhythm, press VAR/
FILL-IN . The variation plays continuously
at the selected tempo.
To insert the fill-in segment in the alter-
nate rhythm, press
VAR/FILL-IN . The
keyboard adds a 1- to 2-measure varia-
tion in the rhythm.
To return to the normal rhythm, press
NORMAL/FILL-IN .
To stop the auto-rhythm, press START/
STOP .
Using ENDING
To end the selected rhythm with a spe-
cial 3- to 8-measure flourish, press
SYN-
CHRO/ENDING while the auto-rhythm is
playing, about 3–8 measures before you
want the rhythm to end. The MD-1600
plays a special ending, then automati-
cally stops the rhythm.
USING
AUTO-ACCOMPANIMENT
The 18 keys on the left side of the key-
board with note labels above them are
called
accompaniment keys.
You can set the MD-1600 to play three
different types of auto accompaniment.
Concert Chord — lets you play chords
on the accompaniment keys using chord
formations of from one to four notes.
The number of keys you press deter-
mines the type of chord that plays.
Standard Fingering — lets you play
chords on the accompaniment keys us-
ing standard chord formations of three
or four notes (see “Standard Fingering”
on Page 20).
Free Session — lets you play the melo-
dy using the entire keyboard while the
MD-1600 plays accompaniment based
on your auto-rhythm selection (see “Us-
ing FREE SESSION” on Page 21).
