System Common Messages
System Exclusive.
This message makes up for all that MIDI doesn't support. (iiiiiii) is usually a seven-bit
Manufacturer's I.D. code. If the synthesizer recognizes the I.D. code as its own, it will
listen to the rest of the message (ddddddd). Otherwise, the message will be ignored.
System Exclusive is used to send bulk dumps such as patch parameters and other non-
spec data. (Note: Real-Time messages ONLY may be interleaved with a System
Exclusive.) This message also is used for extensions called Universal Exclusive
Messages.
Undefined. (Reserved)
Song Position Pointer.
This is an internal 14 bit register that holds the number of MIDI beats (1 beat= six MIDI
clocks) since the start of the song.
l is the LSB, m the MSB.
Song Select.
The Song Select specifies which sequence or song is to be played.
Undefined. (Reserved)
Undefined. (Reserved)
Tune Request. Upon receiving a Tune Request, all analog synthesizers should tune
their oscillators.
End of Exclusive.
Used to terminate a System Exclusive dump (see above).
System Real-Time Messages
Timing Clock.
Sent 24 times per quarter note when synchronization is required (see text).
Undefined. (Reserved)
Start.
Start the current sequence playing. (This message will be followed with Timing
Clocks).
Continue.
Continue at the point the sequence was Stopped.
Stop.
Stop the current sequence.
Undefined. (Reserved)
Active Sensing.
Use of this message is optional. When initially sent, the receiver will expect to receive
another Active Sensing message each 300ms (max), or it will be assume that the
connection has been terminated. At termination, the receiver will turn off all voices and
return to normal (non-active sensing) operation.
Reset.
Reset all receivers in the system to power-up status. This should be used sparingly,
preferably under manual control. In particular, it should not be sent on power-up.
