3-3-1 System Exclusive Messages
Changes internal tone generator settings such as Part and effect settings, remote switch
control, tone generator mode switching, and others via MIDI.
The Device Number of the synthesizer must match the Device Number of the external MIDI
device when transmitting/receiving bulk data, parameter changes or other System Exclusive
Messages. System Exclusive Messages control various functions of this synthesizer, including
master volume and master tuning, tone generator mode, effect type and various other
parameters. Some System Exclusive Messages are called Universal Messages (for example,
GM System On) and do not require a Device Number.
3-3-2 System Realtime Messages
System Common messages control the sequencer.
General MIDI (GM)
System On
When this message is received, the synthesizer will receive MIDI
messages that are compatible with GM System Level 1, and consequently
will not receive Bank Select messages. When the instrument receives the
GM System On message, each receive channel of parts 1 - 16 (in a Multi)
will be assigned to 1 - 16.
For best results, make sure that the interval between this message and the
first note data of the song is a quarter note or longer.
Data Format: F0 7E 7F 09 01 F7 (Hexadecimal).
MIDI Master Volume When this message is received, the Volume MSB will be effective for the
System Parameter.
Data Format: F0 7F 7F 04 01 ll mm F7 (Hexadecimal), in which:
 ll (LSB) = ignored;
 mm (MSB) = appropriate volume value.
Start (FAH) This message lets the MIDI sequence data start playing back from the
beginning.
This message will be transmitted when pressing the [] (Play) button at
the top of the Song or Pattern.
Continue (FBH) This message lets the MIDI sequence data start playing back from the
current song position.
This message will be transmitted when pressing the [] (Play) button at
the middle of the Song or Pattern.
Stop (FCH) This message causes MIDI sequence data (song) to stop playing back.
This message will be transmitted when pressing the [] (Stop) button
during playback.
Active Sensing (FEH) This is a type of MIDI message used to prevent unexpected results when
a MIDI cable is disconnected or damaged while the instrument is being
played.
Once this message has been received, if no MIDI data is subsequently
received within an interval period, the same function is performed as when
All Sounds Off, All Notes Off, and Reset All Controllers messages are
received, and the device returns to a status in which FEH is not monitored.
The interval period is approximately 300 msec.
Timing Clock (F8H) This message is transmitted with a fixed interval (24 times per 1/4 note) to
synchronize connected MIDI instruments.
