REAL TIME
These messages are used for the real-time control of specific modules or functions of a connected
instrument. These messages include the Start, Stop, Pause/Continue and Clock commands.
START: the sequencer has started to record or play back a MIDI sequence
STOP: the sequencer has been stopped
PAUSE / CONTINUE: the sequencer has been set in stop status
CLOCK: the sequencer speed
N.B.
The organ does not transmit / receive the messages described above. They are described for your information only.
The Real Time messages also include the Active Sensing code, sent to keep the dialogue between two
MIDI instruments alive. When the receiver instrument does not receive any MIDI data or the Active
Sensing code in a time interval of about 300 milliseconds, it considers the MIDI connection to have been
deactivated, so it switches off any notes still active. Remember that the transmission and reception of this
message is optional, so not all instruments are equipped to handle it.
