Tune
The TUNE function allows you fine tune the instrument. The tuning can vary
between 427.5 Hz and 452.5 Hz (corresponding to an excursion of approx. one
semitone) in steps of +/– 0.5 Hz. The default status of the instrument
corresponds the equal standard A = 440 Hz.
1. Press and hold the TUNE function key (D7) and press either the DATA Ħ
or the DATA Ĥ button to raise or lower the tuning accordingly.
The first time you press the DATA
Ħ
or DATA
Ĥ
button, the instrument
will automatically play a sinusoidal reference sound (A = 440 Hz).
To raise the tuning
2. While still holding down the TUNE function key (D7), press the DATA Ħ
button again to obtain the first increment (+0.5 Hz).
Continue in this way until you obtain the required tuning level. The
sinusoidal reference sound will help you fine tune the instrument.
Release the TUNE function key (D7) to escape the function.
To lower the tuning
3. While holding down the TUNE function key (D7), press the DATA Ĥ
button to activate the function.
You will hear the reference sinusoidal sound play with the last set tuning
(the one set in step 2 above).
Press DATA
Ĥ
again to obtain the first decrement (–0.5 Hz) and
continue in this way until you obtain the required tuning level.
Release the TUNE function key (D7) to escape the function.
The current Tune setting will remain memorized even after turning the
instrument off. To restore the pitch to normal, see step 4 below.
To reset the tuning
4. Hold down the TUNE function key (D7) and press both the DATA Ħ/Ĥ
buttons at the same time.
You will hear the reference sinusoidal sound play with the standard
Pitch (C=C), or with the current Transpose pitch.
