Active Sensing Messages
These messages monitor the integrity of MIDI connections. When the MIDI IN connec-
tor receives Active Sensing messages, it will enter the ‘Active Sensing’ mode. If Active
Sensing messages (or other MIDI messages) are not received at 420 millisecond
intervals, the device will judge that a cable is disconnected or there is a damaged
connection. All sounds will be cut off, and a Reset All Controllers message will be
processed. Monitoring for Active Sensing messages is terminated.
System Exclusive Messages
Exclusive messages are used to control a characteristic operation of the device. Universal
System Exclusive messages can be used for all devices - regardless of the manufacturer.
General Exclusive messages, however cannot convey data between different models.
Roland’s Exclusive messages have a unique manufacturer ID, device ID, and model ID
so that the type of data can be determined.
•GM System On (Universal Non-Realtime System Exclusive)
✩
When the ‘GM System On’ message is received, the unit will be set to correspond with
the General MIDI basic settings. Reception of NRPNs will no longer be allowed after a
‘GM System On’ has been received.
The ‘GM System On’ MIDI message is included at the beginning of song data that carries
the GM logo. When the song data is played from the beginning, the device will be auto-
matically initialized to the basic settings.
•GS Reset (GS Format Common System Exclusive)
When the ‘GS Reset’ message is received, all the GS basic settings are restored on the
unit. When a GS reset is received, the NRPNs specified with the GS Format can be
received.
The GS reset MIDI message is included at the beginning of song data that carries the GS
logo. When the song data is played from the beginning, the device will automatically
be initialized to the basic settings.
