mLAN, short for Music Local Area Network, is a transport level protocol for synchronized transmission and management of multi-channel digital audio, video, control signals and multi-port MIDI over a network.


The mLAN protocol was originally developed by Yamaha Corporation, and publicly introduced in January 2000.[1] It was available under a royalty-free license to anyone interested in utilizing the technology.

mLAN exploits several features of the IEEE 1394 (FireWire) standard such as isochronous transfer and intelligent connection management. There are two versions of the mLAN protocol. Version 1 requires S200 rate, while Version 2 requires S400 rate and supports synchronized streaming of digital audio at up to 24 bit word length and 192 kHz sample rate, MIDI and wordclock at a bitrate up to 400 Megabits per second.

With the proper driver software, a computer-based digital audio workstation can interact with mLAN-compliant hardware via any OHCI-compliant FireWire port. mLAN consumes the entire bus bandwidth when operating and non-mLAN devices cannot share the same Firewire connection, so it is not possible to use hard drives, optical drives or other sound devices on the same Firewire bus when mLAN Manager software is running.

The transport layers of mLAN have been standardized as IEC 61883.[2]

End of life[edit]

By 2005, over 100 manufacturers were part of the mLAN Alliance[3] however very few actual products had surfaced.

As of early 2008, mLAN appeared to have reached the end of its product life. Third party developers discontinued or retracted their mLAN products from the market, and Yamaha itself ceased any new releases of mLAN hardware or updates to the mLAN software and drivers. Even though more recent FireWire based products from Yamaha could interoperate with earlier mLAN devices using a computer, any mention of mLAN is notably absent from new product announcements and driver updates.
