Master Tuning - Roland HP-1 Owner's Manual

4.3 Master Tuning

When playing in ensemble with other instruments, you can adjust the HP-1's reference pitch to that of another instru-
ment.
Middle A ("A4") is generally used for adjusting the tuning of the instruments. When playing in ensemble with other
instruments, tune each instrument to the same reference pitch. "440Hz" is the power-on default for the reference pitch.
The following operations only work after selecting the HP-1's Function mode (see p. 12 for how to select it).
Sounding the A4 note
While tuning, it is of utmost importance to compare
the HP-1's tuning with that of the external instrument
or device. Since the keyboard is used for setting the
Function parameters, it is no longer available for play-
ing that note the normal way.
That is why there are six keys that allows you to sound
the A4 note. These are the first six keys in the tuning
range indicated on p. 12:
Press these keys to sound the
A4 note.
Lowering/ raising the reference pitch
The following keys ("G1" and "G#1") can be used for
lowering or raising the HP-1's pitch in very small
steps:
Press the "G1" note to lower the reference pitch, or
the "G#1" note to raise it.
Each time you press the "G1" key, the pitch will fall by
0.1 Hz. If you continue holding the key, the pitch will
continue falling.
Each time you press the "G#1" key, the pitch will rise
by 0.1 Hz. If you continue holding the key, the pitch
will continue rising.
Higher
Lower
Returning to 440Hz
Press the "A1" key on the keyboard.
Return to 440Hz
The reference pitch will be set to 440.0 Hz. This is the
most commonly used setting.
Setting the reference pitch to 442Hz straight
away
"442Hz" is a popular tuning pitch for concert grands.
Rather than trying to set it using the "G1" and "G#1"
keys, you can press the "A#1" key to select that tuning
right away:
The standard pitch will be set to 442Hz, and all other
notes will change accordingly.
