Technical Explanations
The audio/MIDI data that flows over mLAN is transferred using virtual connectors called “mLAN
plugs.” The logical routes that are established between these plugs are called “mLAN connec-
tions.”
Figure 9: An example of audio signals
An mLAN connection is expressed as the combination of
• transmitting device — transmitting mLAN plug (mLAN output plug)
• receiving device — receiving mLAN plug (mLAN input plug)
Figure 10: An example of an mLAN connection
The mLAN connection manager is a function possessed by all mLAN devices, and is a module that
manages the specified mLAN connections on each node.
The mLAN connection manager has the following functionalities:
• By request from another mLAN node, it creates mLAN connections in the mLAN plug of the
mLAN nodes.
• In response to inquiry from another software module, it provides mLAN connection data.
• When the bus is reconfigured due to a bus reset or power-off, it is able to automatically
restore mLAN connections.
