SYSTEM MESSAGES

System messages are the data related to the overall system
of the device.
I System Exclusive Messages
System Exclusive messages control various functions of
the S03, including master volume and master tuning,
tone generator mode, effect type and various other
parameters.
General MIDI Mode On
When General MIDI mode on is received, the tone
generator mode will be changed to XG mode.
When this happens, the S03 will receive the MIDI
messages which are compatible with GM System Level 1,
and consequently will not receive NRPN and Bank Select
messages.
Since approximately 50ms is required to execute this
message, be sure to leave an appropriate interval before
the subsequent message. The S03 responds to this
message only when it is set to the Multi mode.
F0 7E 7F 09 01 F7 (Hexadecimal)
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
XG System On
When this data is received, the S03 will switch to XG
mode and all the parameters will be initialized
accordingly, and XG-compatible messages such as NRPN
and Bank Select messages can be received.
Since approximately 50ms is required to execute this
message, be sure to leave an appropriate interval before
the subsequent message. The S03 responds to this
message only when it is set to the Multi mode.
F0 43 1n 4C 00 00 7E 00 F7 (Hexadecimal)
*n = device number (normally set to "0")
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
S03 does not respond to MIDI data, such as when
using the Compare function or when in the Demo
mode.
I Active Sensing (Receive only)
Once FE (Active Sensing) has been received, if no MIDI
data is subsequently received for longer than an interval
of approximately 300msec, the S03 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 FE is not monitored.
Refer to the MIDI Data Format in the "Data List" book
for more information on the various messages.
