Roland MP-500 Changing Tuning Curves

Convenient Functions

When you want to perform using a tuning other than equal

temperament, you’ll need to specify the keynote (tonic for

major, sixth for minor) appropriate for the key of the song

you want to play.

Key Temperament Description

Equal With this tuning, the octave is divided

into twelve equal intervals. Regardless

of the interval, very little ambiguity is

produced.

Pythagorean Developed by the philosopher

Pythagoras as a method of tuning that

resolved the ambiguousness of fourths

and fifths. As a result, melodies sound

cleaner, but a certain amount of

ambiguousness is produced with

triads.

Just Major This tuning eliminates the

ambiguousness of fifths and thirds.

This tuning is not suitable for melodies,

and transposition is impractical, but

rich sonorities can be produced by

chords.

Just Minor Just Major and Minor tunings are

different. You can get the same effects

in the minor scale as in the major scale.

Mean Tone A partial compromise of the Just Major

tuning, created to make transposition

possible.

Werckmeister A combination of the Mean Tone and

Pythagorean tunings. This tuning can

be used in all keys.

Kirnberger As a result of improvements made to

the Mean Tone and Just temperaments,

it is relatively tolerant towards

transposition, and can be used to play

in all keys.

NOTE

When performing in ensemble with other instruments, be aware

that depending on the key, there may be some shifting of the pitch.

Please tune to the other instruments in the ensemble.

NOTE

When you play back a recorded performance, it will be played using

the temperament that was selected at that time.

Changing Tuning Curves

Pianos are commonly tuned so pitches in the lower registers

are adjusted relatively flat, and pitches in the higher registers

are tuned sharper compared to equal temperament. This

kind of tuning method for the piano is called “Stretch

Tuning.”

The graphic representation of the differences in pitch when

comparing equal-tempered tuning with the actual tuning

used is called the “Tuning Curve.” Changing the tuning

curve results in a subtle change in the sound of the chords.

MP-500 can switch the tuning curve.

“Type 2” (Stretch Tuning) is the power-on default for the

tuning curve.

Key Type Description

Type 1 Standard tuning curve. This is the right

choice when using Dual Play (p. 16), or

when playing in ensemble with other

instruments.

Type 2 A tuning curve wherein the low and

high registers are widened slightly—

low pitches are a little lower, the high

pitches a little higher (Stretch Tuning).

Appropriate for piano solos.

NOTE

This setting is only available with piano tones.
