TUNING THE KEYBOARD
Although your Concertmate 970 never
goes out of tune, it does let you adjust
its pitch to match other instruments or
musical recordings.
Note: You cannot tune the keyboard
while the juke box mode is turned on.
1. Press and hold SOUND , then
press and release JUKE BOX . The
display shows the current pitch
setting.
Note: The number on the display
is the number of “cents” to which
the keyboard is currently tuned,
compared to its default pitch. A
cent is the measurement that rep-
resents the acoustical interval
between two tones. 1200 cents
equal 1 octave.
2. Within 5 seconds, repeatedly
press TRANSPOSE/TUNE s or t to
raise or lower the keyboard's
pitch. Each time you press the
key, the number on the display
increases or decreases by 1
(cent).
