Convenient Functions
Setting the
reference pitch and
temperament (Tuning)
Refer to p. 43 for the procedure.
Tuning
In situations such as when playing in ensemble with other
instruments, you can adjust the HPi-5’s reference pitch to that of
another instrument. Middle A is used as the reference pitch for
tuning instruments.
The process of adjusting the reference pitch to match another
instrument is called “Tuning.”
Setting
415.3 Hz–440.0 Hz—466.2 Hz
Stretch Tuning
Pianos are generally tuned so that the low range is flatter and the
high range is sharper than equal tempered pitches. This method of
tuning is unique to the piano, and is known as “stretched tuning.”
Setting
On
This tuning curve expands the low range and high range. It
is suitable for piano solos. This setting is selected when the
power is turned on.
Off
This is the standard tuning curve. It is suitable when playing
in an ensemble with other instruments.
Temperament
You can play classical styles such as Baroque using historic
temperaments (tuning methods).
Today, compositions are generally created with equal temperament
in mind and are played using equal temperament. However in past
ages of classical music, a variety of temperaments were used. By
playing in the temperament that was in use when a composition was
created, you can experience the sonorities of chords originally
intended for that song.
Setting
Equal
This temperament divides the octave into 12 equal parts. All
intervals will be slightly out of tune by the same amount.
Just Major
This temperament makes the 5th and 3rd intervals pure. It is
unsuitable for playing melodies and modulation is not possible, but
it produces beautifully harmonious chords.
Just Minor
Just intonation differs between major and minor keys. The same
results as major can be obtained in a minor key.
Arabic
This tuning is suitable for the music of Arabia.
Kirnberger
This temperament is a modification of meantone temperament and
just intonation, allowing more freedom of modulation. It allows you
to play in all keys (third method).
Meantone
This temperament is a partial compromise of just intonation in order
to allow modulation.
Pythagorean
This temperament is based on the theories of the Greek philosopher
Pythagoras, and has pure fourths and fifths. Chords containing a
third will sound impure, but melodies will sound good.
Werkmeister
This temperament is a combination of meantone and Pythagorean
temperaments. It allows you to play in all keys. (First method,
number three.)
Key
When playing in a temperament other than equal temperament, you
must specify the tonic (the note corresponding to C for a major key,
or to A for a minor key) of the key in which you will play.
If you have selected equal temperament, it is not necessary to select
the tonic.
Setting
C, C#, D, Eb, E, F, F#, G, G#, A, Bb, B
Playing back the performance of a
specific instrument (16 Track)
Commercially available SMF music files normally consists of 16
parts, and the performance of a different instrument is recorded on
each part.
Of these 16 parts, you can select and play (solo) a specific part, or
mute (silence) a selected part. (Muting just one specific part of the
playback is referred to as “minus-one.”)
Select a song before you begin the procedure.
Solo and mute can also be specified while playing back the
song.
1
Press the [Function] button, and select “16 Track” in the
screen.
