different notes)
You can play in a different key—without changing the
keys you are playing. That way, even songs originally
written in a difficult key with many ¿(sharps) or,
(flats) (i.e. with many black keys), can be played in a
more convenient way. This is especially useful when
you are used to playing a given song in one key, while
someone else wants you to play it in another key: just
change the Transpose setting and you're there.
The transposition remains in effect until you change it
or until you switch off the HP-137.
[Ex.] Playing in C and sounding in E
1. Press and hold the volume button.
2. While still holding the volume button, use the
C2~B2 notes to select the key. (For our example,
press the second "E" from the left.)

Gray= higher / White= lower
Note: Refer to "Functions assigned to the keyboard" on
page 16 for the exact keys to press.
3. To return to the previous condition, hold down the
volume button while pressing the C2 key.
Note: The transposition only applies to the notes you play
on the HP-137's keyboard. It does not apply to note mes-
sages received via the MIDI IN connector.
In situations such as when playing in ensemble with
other instruments, you can adjust the HP-137's refer-
ence pitch to that of another instrument.
Middle A ("A4") is generally used for tuning instru-
ments. When playing in ensemble with other instru-
ments, tune each instrument to the same reference
pitch.
"440Hz" is the power-on default for the reference
pitch,
Lowering/ raising the reference pitch
1. Press and hold the volume button.
2. While still holding the volume button, press the
"C4" note to lower the reference pitch, or the "D4"
note to raise it.
Note: Refer to "Functions assigned to the keyboard" on
page 16 for the exact location of the keys you need to press.
Each time you press the "C4" 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 "D4" key, the pitch will rise by
0.1 Hz. If you continue holding the key, the pitch will
continue rising.
