Unable to transfer/receive audio data or MIDI data.
Settings on the computer
• The mLAN Driver may not have been installed or set up correctly.
• Make sure that the mLAN Auto Connector or mLAN Graphic Patchbay is active. (See
.)
• When transferring/receiving audio data, make sure to set the bi-directional connection (mLAN device
↔
computer). Only one direc-
tion (only mLAN device
→
computer or only computer
→
mLAN device) may result in improper playback.
Connecting the mLAN device
• Make sure that the FireWire cable is connected properly, and that the power to the mLAN device has been turned on. Disconnect the
FireWire cable once, then insert it again.
• There may be a loop connection. Check the cabling to make sure that none of the devices are connected in a loop.
Example of loop connection
If FireWire devices other than the mLAN devices are connected to the computer, disconnect all FireWire devices from your com-
puter, and try connecting a single mLAN device to your computer.
• There may be multiple FireWire interfaces installed on the computer. Since the mLAN Driver supports only the standard interfaces,
use only the standard FireWire interface of your computer and remove other FireWire interfaces.
Unable to transfer/receive MIDI data or Program changes.
Settings on the computer, mLAN device and other external devices

appropriate MIDI ports.
• Make sure the transmission and reception channels of each device or an application (such as a DAW) match.
• Make sure the MIDI settings of the mLAN device are appropriate.
