Introduction to mLAN Graphic Patchbay

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.

Graphic View

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.

Using mLAN Graphic Patchbay as a Plug-In

You can start mLAN Graphic Patchbay as either stand-alone software or as a plug-in for an Open Plug­in 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.

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.).

OPT Level Implementation for mLAN Graphic Patchbay

This chart shows OPT-compatibility of mLAN Graphic Patchbay.

About the Maximum Number of Connected Nodes

For Windows users:

The Maximum Number of Connected Nodes field in the Node Information (Audio) window
indicates the maximum number of audio nodes that can be connected to the audio input of the
corresponding node.

The Maximum Number of Connected Nodes field in the Node Information (MIDI) window
indicates the maximum number of MIDI nodes that can be connected to the MIDI input of the
corresponding node.

For example, assume that the maximum numbers of connected nodes are as follows:

•The maximum number of connected nodes indicated in the Node Information (Audio)
window: four units

•The maximum number of connected nodes indicated in the Node information (MIDI)
window: two S400s and one S200

In this case, you can connect up to four S400s and S200s combined as Audio nodes to the computer
node.

You can connect up to two S400s and one S200 as MIDI nodes.

NOTE

For Macintosh users:

The Maximum Number of Connected Nodes in the Node Information (Audio) window and the
Node Information (MIDI) window indicate the maximum number of audio and MIDI nodes
combined that can be connected to the corresponding node.

NOTE

On a Windows computer, you can connect only one S200 to a computer
node.

S400 and S200 units are counted differently as nodes.

• If the node is an S400, it would be regarded as two nodes (one audio node
and one MIDI node).

• If the node is an S200, it would be regarded as one node (audio and MIDI
combined).

23

Connector Information Window

In Graphic view, clicking the connector number in the Input or Output window (page 9) displays the

mLAN Connection Settings

This section describes how to connect or disconnect audio or MIDI connectors between nodes, and
change wordclock and other mLAN connection settings.

You can easily change the audio, MIDI or wordclock signal routing in an mLAN network by intuitively
re-patching the cables in the graphic user interface.

Wordclock Settings

There are two ways to set the wordclock:

•Follow the steps described in “Connecting the node inputs and outputs” (page 27) to connect
the wordclock connectors one by one

•Use the [Single Master] option

This section explains how to use the [Single Master] option.

You can easily set up the wordclock by using the [Single Master] option. You do not need to connect the
wordclock connectors one by one. Typically, you will use this option to specify the wordclock master in
an mLAN network.

NOTE

• If you wish to specify two wordclock masters in an mLAN network and
connect the wordclock connectors manually, follow the steps described in the
“Connecting the node inputs and outputs” section (page 27).

• Most functions selected from the Menu bar can also be accessed from the Tool
bar.

1. In the [Connection] menu, select [Wordclock].

The Wordclock Setup window opens.

2. Move the mouse to select the node you wish to assign as wordclock master.

The selected node is highlighted by a solid black frame.

3. In the [Connection] menu, select [Single Master].

25

4. The wordclock connector for each node is connected automatically.

The selected node is assigned as wordclock master, and other nodes as slave.

5. Click the node icon (page 13) for the wordclock master node. (Alternatively, in the
[View] menu, select [Node Information].)

The Node Information (Audio) window opens.

6. Select the sampling frequency in the [Sample Rate] field in the Node Information
(Audio) window.

The sampling frequency specified here will be automatically used by the slave nodes.

NOTE

If the error message “Cannot change” is displayed, refer to “If you cannot
change the sampling frequency or the number of output channels” on page 22.

26

Connecting Node Inputs and Outputs

You can control the audio, MIDI or wordclock signal routings in an mLAN network by connecting the
node inputs and outputs.

You can connect the node inputs and outputs by either (a) patching the cables one by one, or (b)
simultaneously patching multiple cables as a group.

NOTE

•Windows users should also refer to“For Windows Users: Notes Regarding
Node MIDI Connection” on page 32.

•You cannot connect the MIDI or wordclock connectors as a group.

• For wordclock connections, using the [Single Master] option is easier
(page 25).

■ Patching the cables one by one

NOTE

The following procedure applies to the Audio Connection window. However,
you can also follow this procedure to connect the MIDI and wordclock
connectors.

1. Click the [OUT] connector of the node that outputs the signal.

mLAN Graphic Patchbay displays the Output Connector window, which shows enlarged node
connectors and virtual cable connectors.

NOTE

•To connect the wordclock input and output connectors, first turn on the
button (page 13) of the master node before clicking the [OUT] connector.
Otherwise, the Output Connector window will not open.

• If you connect the wordclock input and output connectors, the node with the
output connector is set as master, and the nodes with input connectors are set
as slaves. Slave nodes will use the sampling frequency setting of the master
node.

27

2. In the Output Connectors window, click the box next to the output connector
number to be connected.

A virtual cable connector appears in the box.

3. Click the [IN] connector of the node that receives the input signal.

mLAN Graphic Patchbay displays the Input Connectors window.

4. In the Input Connectors window, click the box next to the input connector to be
connected.

The input and output connectors are now connected by a cable of the same color as the output node.

28

■ Connecting multiple cables simultaneously as a group

NOTE

You must select consecutive connector numbers for group connection.

1. Click the [OUT] connector of the node that outputs the signal.

mLAN Graphic Patchbay displays the Output Connectors window.

2. In the Output Connectors window, click the box next to the number of the first
output connector to be connected.

3. While pressing and holding down the <Shift> key on the computer keyboard, click
the box next to the number of the last output connector to be connected.

A virtual cable connector appears in each of the output connector boxes in the range specified in
Steps 2 and 3.

4. Click the [IN] connector of the node that receives the input signal.

mLAN Graphic Patchbay displays the Input Connectors window.

5. Click the box next to the number of the first input connector targeted for group
connection.

29

6. A virtual cable connector appears in each of the input connector boxes, starting
with the input connector selected in this step. The specified multiple input and
output connectors are connected by a virtual cable of the same color as the output
node.

NOTE

• For group connection, be sure to specify the output connectors first.

• Only a single cable appears in a group connection, or when you connect
consecutive input and output connectors.

30

Disconnecting the Cable

To disconnect the cable, you can either (a) delete it from the pop-up menu, or (b) use the <Delete> key
on the computer keyboard.

■ Deleting the cable from the pop-up menu

1. Right-click the cable you wish to disconnect (on a Macintosh, click the cable while
holding down the <Ctrl> key).

The selected cable is now represented by a dotted line, and a pop-up menu appears. The numbers in
the pop-up menu indicate the connector numbers to which virtual cables are connected.

2. In the pop-up menu, click the number of the connector you wish to disconnect.

The cable connecting to the connector will be disconnected. Selecting [All] will disconnect all
connectors indicated in the pop-up menu.

■ Using the <Delete> key on the computer keyboard

1. Click the cable you wish to disconnect.

The selected cable is now represented by a dotted line.

2. Press the <Delete> key on the computer keyboard.

mLAN Graphic Patchbay displays a confirmation message.

3. Click [Yes].

4. The selected cable is disconnected.

NOTE

If multiple connector connection is represented by a single cable (such as group
connection), this procedure will disconnect all connector connections.

31

For Windows Users:
Notes Regarding Node MIDI Connection

When you make MIDI connections on a Windows computer, note the following:

•Each group of eight ports of the node MIDI OUT connector will be connected to a group of
eights ports on another node’s MIDI IN connector.

•When you connect or disconnect one output connector, other output connectors on the same
node are automatically connected or disconnected.

•The computer’s MIDI IN connectors 1-16 are connected to an S400-compatible device that
features a transfer rate of 400Mbps.

•The computer’s MIDI IN connector 17 is connected to an S200-compatible device that
features a transfer rate of 200Mbps.

•If multiple S200-compatible devices are connected in an mLAN network, you can connect
only one of them to the computer’s MIDI IN connector.

For example, if you connect MIDI OUT 1 on an mLAN16E (an S400-compatible device) to the
computer’s MIDI IN 5, all MIDI OUTs (1-4) on the mLAN16E will be automatically configured as
connectors to the computer’s MIDI INs 1-4. You cannot connect any other nodes to the computer’s
MIDI INs 5-8.

You can connect the MIDI OUT connectors on the nodes of other S400-compatible devices to the
computer’s MIDI IN 9-16.

If a single cable represents bundled multiple cables in an on-screen window, disconnecting one of the
multiple cables will disconnect the other bundled cables.

You can connect the MIDI OUT connector on the mLAN16E (an S400-compatible device) only to
the computer’s MIDI IN 1-16 (dedicated for an S400-compatible device).

Similarly, an S200-compatible device can be connected only to the computer’s MIDI IN 17
(dedicated for an S200-compatible device).

32

Saving and Opening an mLAN Graphic Patchbay File or Template File

You can store mLAN connection settings in a file (extension: *ymp) or in a template file (extension:
*ymt), and retrieve them later. The difference between a file and template file is as follow:

■ File (*ymp)

An mLAN Graphic Patchbay file enables you to store and retrieve all mLAN Graphic Patchbay settings.
If your mLAN devices are fixed, as for example in a home recording environment, store the settings in a
file. Since the file stores an ID number for each device, you cannot use the stored mLAN connection
settings if you replace a unit, even with another unit of the same model.

■ Template File (*ymt)

An mLAN Graphic Patchbay template file enables you to store and retrieve all mLAN Graphic Patchbay
settings other than model nicknames and connector nicknames. If you replace a unit, as long as the new
unit is the same model as the previous unit, you will be able to use the stored mLAN connection
settings.

A template file is useful when you wish to recreate your home-recording mLAN connections on devices
in another studio. If you save your basic mLAN connections in a template file, you will not need to set
up the connections from scratch when you visit another studio. This will enable you to configure a
network quickly and efficiently.

NOTE

File names and template file names on Macintosh computers do not include an
extension.

33

Viewing the mLAN Connection Settings in List View

Using S200-compatible IEEE 1394 devices

When using IEEE 1394 devices of the slower S200 type, the number of available audio transmission
channels in the network is reduced. Before connecting an S200-compatible device to the network, make
sure to change the number of transmission channels with the following procedure.

1. Change the number of output (transmission) channels of each S400-compatible
device from the Node Information (Audio) window so that it does not exceed the
total number of output (transmission) channels of all S200 and S400 devices in the
network. (Refer to the table at the bottom of the Error Messages section.)

NOTE

2. Connect the S200-compatible device to the computer or the mLAN device in the
network.

3. To increase the number of output (transmission) channels of S400-compatible
devices, decrease the number of output channels of the S200 devices from the
Node Information (Audio) window, and change the number of output channels of
the S400 devices.

When connecting an S200-compatible device in step 2, the number of output
channels of the S200 device is set to maximum automatically. Confirm the
maximum number of output channels of the S200 device you are using, then
change the number of output channels on the S400 devices accordingly. For
information on the maximum number of output channels, refer to the owner’s
manual of your particular S200 device.

• If the network includes a non-S400-compatible device, the total number of transmission
channels of all devices will be reduced. mLAN Graphic Patchbay recalls the previous
connections of the mLAN devices in the order of power-up. Channels in excess of the
permitted number will not be connected.

• If five or more mLAN devices (including a computer) have been connected to a network,
the total number of transmission channels for all devices will be limited. For example, if
the sampling frequency is set to 44.1 kHz or 48 kHz, the number of available channels
on a Windows computer would be 86 channels, and on Macintosh it would be 98 chan­nels.

42

■ It takes a while to start mLAN Graphic Patchbay or to update the information
using the Update menu option.

• If you try to update the network information after you connect or disconnect an mLAN

device that does not support S400, the system changes the mLAN transmission speed.
This extra process may slow down the operation. However, the process will not affect
the subsequent performance.
