Fundamentals of mLAN
mLAN is a digital network for music that was developed based on IEEE1394, an industry-standard high-performance data communications protocol.
Digital music environments that do not feature mLAN require dozens of cables for various devices and purposes, including MIDI cables and audio cables to route MIDI and
audio signals. If you wish to make changes to such systems, you must physically disconnect and re-connect these cables.
For example, adding another synthesizer to a system requires two MIDI cables and two
or more cables for audio (for stereo equipment). Making the appropriate connections
may require special knowledge of inputs, outputs, stereo settings, and perhaps connec-
tor impedance.
4
The larger the system, the more complicated and expensive these connections
become, increasing the likelihood of errors and difficulties. It takes time and effort to
investigate such errors and their underlying causes. You may have already experienced
the unpleasantness of tracking various cables through a spider’s web of connections.
mLAN simplifies cable connections by using only one type of IEEE1394 cable, thus
enabling you to configure extremely sophisticated systems. There is no need to repatch cables to change routings of MIDI and audio signals between mLAN devices.

NOTE
Wordclocks
In a system that features multiple digitally-connected devices, all digital devices
must be synchronized when digital audio signals are transferred from one device to
another.
Even if the devices use matching sampling frequencies, if their audio processing timing is not synchronized, they might not receive signals correctly, and audible noise,
glitches or clicks may occur. Synchronization is achieved using a wordclock
(a clock signal that synchronizes all digital audio signals in a system).
In a typical digital audio system, one device operates as the wordclock “master” and
transmits a wordclock signal. The other devices operate as wordclock “slaves,” synchronizing to the wordclock master. To connect the mLAN16E to external devices
via mLAN, in mLAN Auto Connector or mLAN Graphic Patchbay, select a device to
be the master, then set the other devices as slaves. If the mLAN16E is used as a
wordclock slave, it can operate at a sampling frequency of 44.1 kHz, 48 kHz,
88.2 kHz or 96 kHz. If the mLAN16E is used as the wordclock master, it will operate
at the wordclock used by the mLAN16E-equipped device.
The number of available input and output channels may vary depending on
the specific mLAN devices connected. For the best performance, it is
recomended that you connect up to four mLAN devices (including a computer)
in a network. If the network contains an mLAN device that is only compatible
with a low transfer rate (200 Mbps (S200)), the number of devices and channels available for connection will be reduced.
English
For information on setting the sampling frequency and wordclock, refer to the
Installation Guide, or to the mLAN Graphic Patchbay Online Manual, or the owner’s
manual for your device.
11
Making mLAN Connections
In an mLAN system, you can easily configure and maintain the system, connect or disconnect the mLAN connectors on the computer and each mLAN device (virtual audio /
MIDI input and output connectors), and make various mLAN connection settings (such
as synchronization) by using the mLAN Graphic Patchbay and mLAN Auto Connector
software applications. There is no need to re-patch audio and MIDI cables to accommodate various music production environments.
English
mLAN Auto Connectors
This software application enables you to
connect a computer to a single mLAN
device.
It enables you to easily select wordclock and
audio input and output channels.
For information on installing and using the
software, refer to the separate Installation
Guide.
NOTE
mLAN Graphic Patchbay
This graphic software application enables
you to manage mLAN connection settings
for the connected computer and multiple
mLAN devices. You can immediately grasp
connections in their entirety by viewing displayed mLAN system configuration graphics. You can also intuitively modify
wordclock settings and audio and MIDI signal routing, much as if you were connecting
physical cables.
For information on installing and using the
software, refer to the separate Installation
Guide and the mLAN Graphic Patchbay
Online Manual.
You can also use mLAN Graphic
Patchbay to connect a computer
to a single mLAN device.
12
Saving mLAN connection settings to the corresponding mLAN device
When you make mLAN connections on the computer, the connection settings will be automatically saved in the corresponding mLAN devices. Therefore, if you used mLAN Graphic Patchbay to configure a network that excludes a computer, the next time you use the network, you
will be able to activate the network just by turning on the power to the network’s mLAN devices
(without starting the computer).
