When this is received, the Volume MSB will be reflected by
the System parameter MASTER VOLUME.

2.1.3 XG parameter change
This message sets XG-related parameters. Each message can
set a single parameter.
The message format is as follows.
11110000 F0H Exclusive status
01000011 43H YAMAHA ID
0001nnnn 1NH N:device Number
01001100 4CH Model ID

0lllllll LLH Address Low
0sssssss SSH Data

11110111 F7H End of Exclusive
For parameters whose Data Size is 2 or 4, the appropriate
amount of data will be transmitted as indicated by Size.
EXAMPLE OF PARAMETER CHANGE
Changing chorus type to “Flanger1”
First, check the Effect Type List (page 84) to identify
the MSB and LSB numbers; for “Flanger1” Chorus type
numbers are MSB = 43, LSB = 0.
Next, check the Address in Table 1-4 (page 103) for the
CHORUS TYPE parameter; in this case the address is
High,Mid,Low = 02,01,20, respectively.
Apply these to the 2.1.3 XG parameter change list as
follows:
11110000 F0H Exclusive status
01000011 43H YAMAHA ID
0001nnnn 1NH N:device Number*
01001100 4CH XG Model ID
00000010 02H Address High
