CALIBRATION (con’t)
OSCILLATOR 2 FREQUENCY (OSC2 FREQ):
This option allows you to select OSC2 Frequency Calibration. This
calibrates the OSC2 FREQ control so that turning the editing dial all
the way CCW turns OSC2 down exactly a fth (-7 semitones) and
turning all the way CW turns OSC2 up exactly a fth (+7 semitones).
Press ENTER to access the OSC2 Frequency Calibration menu.
You will be asked if you wish to proceed. Use the VALUE knob to se-
lect YES or NO. If you are uncertain, or if you change your mind about
performing this calibration, select NO and press ENTER. You will be
returned to the System Utilities Calibration menu. Otherwise, select
YES and press ENTER.
Calibration will begin, and the display will appear as shown. The rst
number that appears on the display is the base note for calibration
(MIDI note 60). The second number is the calibration value (this is
the value stored in the LP’s EEPROM), and the third number is the
actual measured note, which is displayed in MIDI Note Number Cents
(in the example shown here, ‘64.37’ indicates MIDI note 64, and the
actual measured value is 37 cents sharp). When calibration starts, the
LP rst tunes itself to the base note. As this happens, you will see the
measured note value hone in on 60.00. Then the calibration value will
change as the note climbs to 67.00, at which point it has calibrated the
maximum value (+7 semitones), and then the note descends to 53.00
at which point it has calibrated the minimum value (-7 semitones).
When the calibration is complete, the message ‘SUCCESSFUL’ will ap-
pear on the display and the new calibration values will be stored in the
LP’s EEPROM. To exit the calibration, press ENTER to return to the
System Utilities Calibration menu or press MASTER to exit the calibra-
tion and return to the highest level of the System Utilities menu.
