MIDI 3-3 System Messages 3-3-1 System Exclusive Messages Changes internal tone generator settings such as Voice and effect settings, remote switch control, tone generator more 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 the Device Number. General MIDI (GM) System On When this message is received, the synthesizer will receive the 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. 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. Mode Change When this message is received, the mode of the synthesizer changes. Data Format: F0 43 1n 7F 0D 0A 00 01 0m F7 (Hexadecimal), in which: „ n = Device Number; „ m = 0 - 6. 3-3-2 System Common Message System Common messages also control the sequencer. MIDI Time Code This message lets the current MIDI sequence data position generate in Quarter Frame (F1H) absolute time (hours/minutes/seconds/frames). Song Position Pointer (F2H) This message lets the start position for the MIDI sequence data specify. Song Select (F3H) This message lets the number of the MIDI sequence data specify. 3-3-3 System Realtime Messages System Common messages control the sequencer. Start (FAH) Continue (FBH) 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. 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. 72

System Common messages control the sequencer.
General MIDI (GM)
System On
When this message is received, the synthesizer will receive the 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.
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.
Mode Change
When this message is received, the mode of the synthesizer changes.
Data Format: F0 43 1n 7F 0D 0A 00 01 0m F7 (Hexadecimal), in which:
n = Device Number;
m = 0 - 6.
MIDI Time Code
Quarter Frame (F1H)
This message lets the current MIDI sequence data position generate in
absolute time (hours/minutes/seconds/frames).
Song Position
Pointer (F2H)
This message lets the start position for the MIDI sequence data specify.
Song Select (F3H)
This message lets the number of the MIDI sequence data specify.
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
