SYSTEM MESSAGES

System messages are the data related to the overall
system of the device.

■ System Exclusive Messages

System Exclusive messages control various functions of
the S08, including master volume and master tuning,
tone generator mode, effect type and various other
parameters.
General MIDI (GM) System On
When "General MIDI system on" is received, the tone
generator mode will be changed to XG (Multi) mode.
When this happens, the S08 will receive the MIDI
messages which are compatible with GM System Level 1,
and consequently will not receive NRPN and Bank Select
messages.
F0 7E 7F 09 01 F7 (Hexadecimal)
n Make sure that the interval between this message and
the first note data of the song is at least a quarter note
or greater in length.
GM2 System On
When a "GM2 System on" message is received, the tone
generator mode changes to XG (Multi) mode. When this
happens, the S08 is set to receive the MIDI messages
which are compatible with GM System Level 2.
F0 7E 7F 09 03 F7 (Hexadecimal)
n Make sure that the interval between this message and
the first note data of the song is at least a quarter note
or greater in length.
GM System Off
When a "GM System off" message is received, the tone
generator mode changes to a mode other than GM/GM2
mode. The S08 performs the same function as when an
"XG System on" message is received.
F0 7E 7F 09 02 F7 (Hexadecimal)
n Make sure that the interval between this message and
the first note data of the song is at least a quarter note
or greater in length.
Master Volume
When received, the Volume MSB will be effective for the
System Parameter.
F0 7F 7F 04 01 ll mm F7 (Hexadecimal)
* mm(MSB) = appropriate volume value, ll(LSB) =
ignored

About MIDI
XG System On
When this data is received, the S08 will switch to XG
(Multi) mode and all the parameters will be initialized
accordingly, and XG-compatible messages such as NRPN
and Bank Select messages can be received.
F0 43 1n 4C 00 00 7E 00 F7 (Hexadecimal)
*n = device number (normally set to "0")
n Make sure that the interval between this message and
the first note data of the song is at least a quarter note
or greater in length.
Multi Mode On
F0 43 1n 6C 0A 00 00 01 F7 (Hexadecimal)
*n = device number (normally set to "0")
n There are some operating conditions in which the
S08 does not respond to MIDI data, such as when
using the Compare function or when in the Demo
mode.

■ System Realtime Messages

Active Sensing (Receive only)
Once FEH (Active Sensing) has been received, if no MIDI
data is subsequently received for longer than an interval
of approximately 300msec, the S08 will perform the same
function as when All Sounds Off, All Notes Off, and
Reset All Controllers messages are received, and will then
return to a status in which FEH is not monitored.
n Refer to the MIDI Data Format in the "Data List" book
for more information on the various messages.
