mLAN Graphic Patchbay software enables you to set up and manage connections between mLAN
devices using a graphic computer interface to connect and disconnect virtual audio/MIDI connectors
and to synchronize audio/MIDI signals between mLAN devices.
In this manual, setting up audio, MIDI, and wordclock routings is referred as to as making “mLAN
connections.”
You can immediately grasp the connections in their entirety by viewing displayed mLAN system
configuration graphics. You can also intuitively change audio and MIDI signal routing and wordclock
settings, much as if you were connecting physical cables.

Introduction to mLAN Graphic Patchbay
Menu and Tool bars
These bars enable you to use various functions by selecting
menu options or clicking Tool bar buttons. (pages 7 and 11)
Node
Computers and mLAN
devices in an mLAN network
are called “nodes.” These
graphics provide information
about connected nodes
(page 13).
Input and output connectors
These connectors represent virtual audio/
MIDI/wordclock inputs and outputs for
each node. You can route audio/MIDI/
wordclock signals on an mLAN network by
using the graphic user interface to connect
these connectors (page 25).
Cable
This virtual cable indicates
connected nodes in an
mLAN network.

You can start mLAN Graphic Patchbay as either stand-alone software or as a plug-in for an Open Plug-
in Technology compatible application.
Open Plug-in Technology (OPT) is a new software format that enables you to control MIDI devices
from a music software sequencer. For example, OPT enables you to start and operate various parts
of your music system, such as Plug-in Board editors and mixing control editors, directly from an
OPT-compatible sequencer. OPT also makes it unnecessary to set MIDI drivers for each application,
streamlining your music production system and making all operations more convenient and
seamless.
■ About OPT Levels
The client application and its compatibility with OPT can be divided into three levels, as shown
below.
■ OPT Level Implementation for mLAN Graphic Patchbay
This chart shows OPT-compatibility of mLAN Graphic Patchbay.
All mLAN Graphic Patchbay functions work under the client applications of any OPT level (Panels
(Level 1), Processors (Level 2), and Views (Level 3)).
Certain operations may not work as expected if there is no corresponding
function in the client application (sequencer, etc.). The highest level of
implementation for the client application is indicated in the OPT logo (which
appears along with the version information in the application).
Using mLAN Graphic Patchbay as a
Plug-In
Level 1 (OPT Panels) provides basic support for opening and displaying OPT control
panels that can transmit data via a clients’ external MIDI connectors.
Typically, this enables basic hardware editor control panels to operate properly.
Level 2 (OPT Processors) provides support for real-time MIDI processors and panel
automation. Typically, this enables both real-time and offline MIDI effects (e.g.,
arpeggiators, transposers, etc.) to operate properly and supply automation to OPT
panels.
Level 3 (OPT Views) provides support for edit views and MIDI processors and panels
that require direct access to client sequencer storage structures.
Typically, this enables support of sophisticated MIDI edit views (e.g., list editors, auto
accompaniment, data checkers, etc.).

Operational Flow
■ If multiple IEEE1394 interface cards have been installed on the computer:
mLAN Graphic Patchbay cannot simultaneously operate mLAN devices connected to multiple
IEEE1394 interface cards.
• Windows
Before you start mLAN Graphic Patchbay, select in the mLAN Driver Setup window the IEEE1394
interface card you wish to use (page 20).
• Macintosh
Connect an mLAN device to a single IEEE1394 interface card.
If multiple IEEE1394 cards have been installed in the computer, a computer node for each card will
be displayed in the Graphic Patchbay screen. However, you can make an mLAN connection (page 25)
only for the node representing the card that is connected to an mLAN device.
To find out which IEEE1394 card (connected to an mLAN device) corresponds to which node, check
the [Vendor] name displayed in [1394 Adapter Card ID] in “mLAN Driver Setup.” (page 20)
If you cannot make an mLAN connection for some reason, make sure that the
IEEE1394 card (connected to the mLAN device) has been selected in the OMS
Setup and ASIO mLAN Control Panel windows. (Refer to “Changing the
Settings after Installation” and “OMS Setup” in the Installation Guide.)
