<Example 3> Retrieving data for Temporary Performance (RQ1)

*When a data transfer is executed in Utility mode, data that is accessed will be the same as that which is transmitted when the Type parameter is set to PERFORM and the Source parameter is set to TEMP: -PATCH

The “Parameter Address Map” gives the following start addresses for Temporary Performance data.

01 00 00 00H	Temporary Performance Common
01 00 10 00H	Temporary Performance Part 1
:
01 00 1F 00H	Temporary Performance Part 16

Since Performance Part has a size of 00 00 00 19H, we add that size to the start address of the Temporary Performance Part 16, resulting in:

01 00 1F 00H +) 00 00 00 19H 01 00 1F 19H

Thus, the Size for the retrieved data will be:

01	00	1F	19H
-) 01	00	00	00H
00	00	1F	19H

Calculating the checksum as shown in <Example 2>, we get a message of F0 41 10 6A 11 01 00 00 00 00 00 1F 19 47 F7 to be transmitted.

Part and Rhythm Set data (RQ1)

*When a data transfer is executed in Utility mode, the data that is accessed will be the same as that which is transmitted when the Type parameter is set to PERFORM and the Source parameter is set to TEMP: +PATCH

The “Parameter Address Map” gives the following start addresses for Temporary Performance, Performance Mode Temporary Patch and Performance Mode Temporary

Rhythm.
01	00 00 00H	Temporary Performance
02	00 00 00H	Performance Mode Temporary Patch (part 1)

The Patch offset addresses are as follows.
00	00H	Patch Common
10	00H	Patch Tone 1
:
16	00H	Patch Tone 4

Since Patch Tone has a size of 00 00 01 01H, we add this size to the start address of Performance Mode Temporary Patch (Part 16) Tone 4, to get:

02 0F 00 00H

1600H +) 00 00 01 01H 02 0F 17 01H

Thus, the size of the retrieved data will be:

MIDI Implementation

■Scale Tune Function

(Model ID: 42H (GS), address: 40 1x 40H)

Scale Tune is a function that makes fine adjustments to the pitch of each note C-B. Settings are made for one octave, and applied to the notes of all octaves. By making Scale Tune settings you can use tunings and temperaments other than the standard Equal Temperament. Here we give three types of settings as examples.

*Scale tune messages for any parts are recognized in the patch mode.

❍Equal Temperament

This temperament divides the octave into 12 equal steps, and is the temperament most frequently used today, especially in western music. Initially, the Scale Tune function of this instrument is set to Equal Temperament.

❍Just Intonation (tonic of C)

The primary triads sound more beautiful in just intonation than in equal temperament. However, this applies only in one key, and chords will be discordant if you play in a different key. The settings here are for a tonic of C.

❍Arabian-type Scale				Appendices
The Scale Tune function allow you to use various tunings of ethnic music. Here is one of the
Arabian scales.
Setting examples
Note	Equal Temp.	Just (in C)	Arabian-type Scale
C	0	0	-6
C#	0	-8	+45
D	0	+4	-2
Eb	0	+16	-12
E	0	-14	-51
F	0	-2	-8
F#	0	-10	+43
G	0	+2	-4
G#	0	+14	+47
A	0	-16	0
Bb	0	+14	-10
B	0	-12	-49

The values in the above table are in units of 1 cent. Convert these values to hexadecimal, and transmit them as exclusive data. For example to set the Scale Tune of Part 1 to an Arabian-type scale, transmit the following data.

F0 41 10 42 12 40 11 40 3A 6D 3E 34 0D 38 6B 3C 6F 40 36 0F 76 F7

■ASCII Code Table

On the JV-1010, the following ASCII code set is used for processing data such as the Patch Name and the Performance Name.
