System Messages<br />

System messages are the data related to the overall system of the device.<br />

System Exclusive Messages<br />

The Device number of the synthesizer must match the Device Number of the external MIDI device when<br />

transmitting/receiving bulk data, parameter changes or other system exclusive messages. System<br />

Exclusive messages control various functions of this synthesizer, including master volume and master<br />

tuning, tone generator mode, effect type and various other parameters.<br />

Some System Exclusive messages are called “Universal message” (ex. GM System ON), and do not<br />

require the Device Number.<br />

General MIDI (GM) System On<br />

When “General MIDI system on” is received, the synthesizer will receive the MIDI messages which are<br />

<strong>com</strong>patible with GM System Level 1, and consequently will not receive Bank Select messages.<br />

When the instrument receives the GM System On, each receive channel of Parts 1 – 16 (in a Multi) will be<br />

assigned to “1 – 16.”<br />

NOTE Make sure that the interval between this message and the first note data of the song is at least a quarter<br />

note or greater in length.<br />

MIDI Master Volume<br />

When received, the Volume MSB will be effective for the System Parameter.<br />

* mm (MSB) = appropriate volume value, ll (LSB) = ignored<br />

F0 7F 7F 04 01 ll mm F7 (Hexadecimal)<br />

Mode Change<br />

When received, the mode of the synthesizer will be switched.<br />

* n = Device Number (page 138)<br />

* m = 0 – 6 (0: Voice, 1: Performance, 2 – 3: not used, 4: Master, 5: Multi, 6: Demo)<br />

System Realtime Messages<br />

Active Sensing (FEH)<br />

Once FEH (Active Sensing) has been received, if no MIDI data is subsequently received for longer than an<br />

interval of approximately 300 msec, the <strong>S90</strong> <strong>XS</strong>/<strong>S70</strong> <strong>XS</strong> will perform the same function as when All Sounds<br />

Off, All Notes Off, and Reset All Controllers messages are received, and will then return to a status in which<br />

FEH is not monitored.<br />

Timing Clock (F8H)<br />

This message is transmitted with a fixed interval (24 times per 1/4 note) to synchronize connected MIDI<br />

instruments. You can select whether the sequencer block uses the internal Timing Clock, or external<br />

Timing Clock messages received via MIDI IN by setting the MIDI Sync parameter: [UTILITY] MIDI <br />

MIDI Sync.<br />
