mLAN Control Panel’s Manual
“mLAN Control Panel” software enables you to set various parameters when you are using
mLAN with a Macintosh computer. For example, it lets you specify the number of sequences
and the sampling frequency of audio and MIDI data received or transmitted via mLAN, and
specify where to receive or transmit such data. The settings made using the mLAN Control
Panel apply globally to all application programs used with mLAN.
The settings are stored as the “mLAN Control Panel Prefs” file in the “System
folder”
→
“Preferences”
→
“mLAN Prefs” folder. For example, if you have
checked (selected) the “Send” parameter in the mLAN Control Panel window,
when you start the computer next time the stored settings will automatically be
read and data will be output to mLAN according to the settings.

A
FireWire Card ID
This parameter displays the serial number of the FireWire (IEEE1394) interface card. If mul-
tiple interface cards are installed on the computer, select the desired card here.
B
Sample Rate
This parameter enables you to specify the sampling frequency of audio data used via
mLAN. This rate is applied to all reception and transmission of audio data via mLAN.
Options currently supported are “44.1kHz” and “48kHz.”
mLAN supports a sample bit resolution of up to 24-bit for received and trans-
mitted audio data, although this bit resolution may not be available depend-
ing on the application program being used.

Send
This column enables you to set parameters for mLAN data transmission.
Checking the “Send” checkbox enables data transmission to the mLAN bus, and lets you
make the necessary settings for transmission. If you do not perform mLAN transmission,
remove the check from the checkbox.
If you check the “Send” checkbox, mLAN data is always transmitted from the
current computer even if you are not using mLAN. This applies a load to the
entire system, including non-mLAN-related application programs. Remove
the check from this checkbox when you are not using mLAN.
D Isochronous Ch.
This parameter displays the Isochronous Channel number of the FireWire channel being
used for mLAN data transmission. The channel number ranges from 0 through 63, and
unused number is automatically assigned. The bar graph on the right displays the
progress of transmission. The bar graph scrolls when data is being transmitted, and it
stops when no data is transmitted.
E
Audio Sequences
This parameter enables you to specify the number of sequences of mLAN audio data
transmitted from the computer. One sequence corresponds to one channel. The value is
an even number ranging from 0 through 32. The specified number of monaural audio
sequences is always output to FireWire, regardless of whether the current application uses
mLAN. (If the application program does not use mLAN, mLAN audio data indicating
“silence (flat waveform with a level of 0)” will be output.)
F
MIDI Sequences
This parameter enables you to specify the number of sequences of MIDI data transmitted
from the computer via mLAN. One sequence corresponds to one MIDI cable. The value
ranges from 0 through 8. The specified number of MIDI sequences is always output to
FireWire, regardless of whether the current application uses mLAN. (If the application pro-
gram does not use mLAN, mLAN MIDI data indicating “No data” will be output.)
The higher the number of sequences, the greater the load applied to the
computer. Set the minimum value possible. The actual number of sequences
that can be correctly transmitted depends on the performance of your com-
puter and the type of application program.

OFit Sequences
If the number of sequences does not match the actual number in the received data, a red
warning message “Not Match” flashes to the right of the number parameter. To match
the number to that of the data being received, click this button.
While the “Not Match” message is flashing, audio/MIDI data cannot be cor-
rectly received (recorded) from the application.
PReceive Status
This parameter displays the status of the data being received. If mLAN data is received
properly, the “Sample Rate” parameter displays the sampling frequency of the data. The
fields below display symbols that represent the data sequence in each format received.
The symbol “o” indicates that data in the corresponding format is being received.
The symbol “-” indicates that data in a different format is being received.
For example, the symbol “oooooooo-” in the “IEC60958” field indicates that nine
sequences have been received, and the first eight sequences are in the IEC60958 audio
data format. The “Unknown” field displays symbols if sequences in unknown formats are
received.
These fields are blank if no mLAN data is received.
If an error occurs during reception, a red warning message flashes to the right of the
“Sample Rate” parameter. In this case, check the transmission device.
Some error messages, such as “Data Protected,” may not disappear even after
the cause of the error is removed, until reception resumes. In this case,
remove the “Receive” checkbox, click the [Set] button, then check the
“Receive” checkbox again and click the [Set] button.
QBuffers
This parameter enables you to specify the number of buffers for reception inside the
mLAN driver. The setting range is 2 through 20. The smaller the value, the less the delay
created during audio or MIDI data reception.
If you specify too small a value, the system may not work correctly, depend-
ing on the computer’s performance.
RBuffer Length
This parameter enables you to specify the length of a reception buffer inside the mLAN
driver in units of milliseconds, in the range of 1 through 100. The smaller the value, the
less the delay created during audio or MIDI data reception.
If you specify too small a value, the system may not work correctly, depend-
ing on the computer’s performance.
The specified value may change, depending on the other parameter settings.

mLAN OMS Driver’s Manual
The “mLAN OMS Driver” software is used for MIDI data transfer with the mLAN bus via OMS.
Using the mLAN OMS Driver enables MIDI data transmission and reception via mLAN, using
sequencer software that supports OMS.
First, install mLAN driver and OMS.
Drag and drop the “OMS mLAN” file into the “OMS” folder inside the “System” folder.
When you start the OMS Setup application and select “MIDI Cards & Interfaces...” from the
“Studio” menu, mLAN icons equivalent to the number of installed FireWire (IEEE1394) inter-
face cards appear.
OMS regards mLAN as MIDI interface. Therefore, to transmit and receive MIDI data, select
“Studio” →“New device...” and create a number of devices to match the number of ports
used by mLAN, and connect them under the mLAN device. It is a good idea to name these
devices, for example, as “mLAN port#1,” “mLAN port#2,” etc.
What is the mLAN OMS Driver?
Installing the driver
Two FireWire interface cards are installed.
The first card uses two ports for MIDI.

16
Double-click the mLAN device icon, or select the mLAN device and select “MIDI Device
Info...” from the “Studio” menu. The following Device Info dialog box appears.
In this dialog box, you can use the pop-up menus in the “Send” and “Receive” columns to
specify which mLAN MIDI sequences (that are transmitted and received by the computer) are
assigned to which port.
The settings are stored as “mLAN OMS Driver Prefs” in the “mLAN Prefs” folder
inside the “Preferences” folder in the “System” folder.
The maximum number of ports is 8, but the maximum number of ports that can
actually be used equals the number of MIDI sequences specified in the mLAN
Control Panel. You cannot use sequences that have already been used by another
application.
AFireWire Card ID
This parameter displays the serial number of the FireWire (IEEE1394) interface card.
BDisable All
Click this button to disable all pop-up menus in the Channel Assignment column. Under
this condition, clicking [OK] will disable mLAN operation via the mLAN OMS driver.
CRevert
Click to reset the dialog box to its original status when first opened.
DOK
Click to enable the dialog box settings and close the dialog box.
ECancel
Click to close the dialog box without changing the settings.
The changes made to the dialog box become valid immediately when you
