Edirol UA-20 Owner's Manual page 63

Depending on the virtual memory setting or network-related settings, noise
may occur.
Please make the following settings before use.
• [Mac OS 8.6 or 9] In Chooser of the Apple menu, set AppleTalk to
"Inactive."
(This setting is not changed as a result of turning off AppleTalk, as requested
by OMS when sequencer software is started up. You must change the setting
yourself using the "Chooser.")
• [Mac OS 8.6 or 9] In the "Memory" Control Panel, set Virtual Memory to
"Off."
• Depending on the way in which you connect to the Internet, use the UA-20
with the following settings.
If you connect to the Internet via a LAN cable
Use while the LAN cable is connected.
If you connect to the Internet via the internal modem port, or are not
connected to the Internet
In the "TCP/IP" Control Panel, set "Connect via" to "PPP."
After you have made the settings, restart your Macintosh.
* Do not use software that accesses the network (such as a Web browser) at the same time
that you are using sequencer software or audio editing software.
Playback/recording stops midway, and subsequent
playback/recording is not possible
While you were using the UA-20, could your computer have performed a task
with a heavy processing load, such as accessing a CD-ROM drive or network?
If a heavy processing load occurs while the UA-20 is being used, it may not work
correctly. In this case, stop playback/recording, and then start playback/recording
once again. If you are still unable to play/record correctly, close all software that had
been using the UA-20, and re-connect the UA-20.
