MIDI Implementation
●The Scale Tune Feature (address: 40 1x 40)
The scale Tune feature allows you to finely adjust the individual pitch of the notes from C
through B. Though the settings are made while working with one octave, the fine
adjustments will affect all octaves. By making the appropriate Scale Tune settings, you can
obtain a complete variety of tuning methods other than equal temperament. As examples,
three possible types of scale setting are explained below.
❍Equal Temperament
This method of tuning divides the octave into 12 equal parts. It is currently the most widely
used form of tuning,
especially in occidental music. On this instrument, the default settings for the Scale Tune
feature produce equal temperament.
❍Just Temperament (Keytone C)
The three main chords resound much more beautifully than with equal temperament, but
this benefit can only be obtained in one key. If transposed, the chords tend to become
ambiguous. The example given involves settings for a key in which C is the keynote.
❍Arabian Scale
By altering the setting for Scale Tune, you can obtain a variety of other tunings suited for
ethnic music. For example, the settings introduced below will set the unit to use the Arabian
Scale.
Example Settings
Note name Equal Temperament
C 0
C# 0
D 0
D# 0
E 0
F 0
F# 0
G 0
G# 0
A 0
A# 0
B 0
The values in the table are given in cents. Refer to the explanation of Scale Tuning to convert
these values to hexadecimal, and transmit them as exclusive data.
For example, to set the tune (C-B) of the Part1 Arabian Scale, send the data as follows:
F0 41 10 42 12 40 11 40 3A 6D 3E 34 0D 38 6B 3C 6F 40 36 0F 50 F7
