SPECIAL FEATURES
CHANGING KEYS
The Concertmate 970 automatically
selects the key of middle C each time
you turn it on.
For added flexibility as you make mu-
sic, the Concertmate 970 lets you
change (transpose) the musical key in
which it plays.
1. Press and hold
SOUND
, then
press and release
RHYTHM.
The
display shows the current key set-
ting
.
Note: The number on the display
is the number of “semitones” to
which the keyboard is set, com-
pared to its default key. A semi-
tone is a measurement that
represents the acoustical interval
between the keys of any two keys
on the keyboard. For example, the
difference between C and C or B
and B is one semitone. You can
transpose the key down 6 semi-
tones (to an F ) and up 5 semi-
tones (to an F) — a full octave.
2. Within 5 seconds, press

s
or t to raise or lower

key, the number on the display in-
creases or decreases by 1 (semi-
tone).
