Observations:
The Set function of the System Exclusive is able to automatically identify the amount of the field to update, regardless of the
format with which the data is sent with the following exceptions:
∑ the format 0 always modifies a bytes relating to the addres of the variable to update, therefore, if for example, we want to
modify with format 0 a variable of 32 bits of the current value equalling 0x12345678 (hexadecimal value), after sending the data
0x7F we will obtain the variable updated to the value 0x7F345678. The correct method to update a variable with a value greate
than 7 bit (correspnding to the decimal value 127) is to use the format 1 or 2; in the way, to update a 16 bit variable to the
hexadecimal value 0x1234 you can send:
format 1:
format 2:
∑ the formats 4 and 5 do not consider the limits accepted by the filed in memory for which case should be taken not to send a
numder of data higher than the accepted limit.
APPENDIX B
Creation of RESOURCE ACCESS files.
To control the resources via system exclusive (RESOURCE ACCESS) makes use of the solution of packaging the various files
which constitute the same resource into a single buffer.
Generally, therefre, we would have the following situation:
for a total of (n+2) files (with n which can also be 0).
Each file can be identified by a set of three numbers which represente their own description:
This document wants to indicate how to identify the files concerned for each resource to be accessed, how to operate to manipu-
late these files and, finally, the effective transmission mode.
Types of Resources
The resources can be classified as follows:
for each of which concern various files
For each of the resourcces available, it is possible to send a command requesting all the resources which make up the part of that
groups (all the SOUNDS, all the SONGS, ...), or, it is possible to refer to a single resource of the currently selected group (send the
selected SONG, the selected STYLE, ...).
