Troubleshooting
Depending on the virtual memory setting or network-related settings, noise
may occur.
Please make the following settings before use.
•
[Mac OS 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 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-25
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.
While you were using the UA-25, 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-25 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-25, and re-connect the UA-25.
Is the sample rate setting in your software the same as the sample rate of the
digital device connected to the digital input connector?
Set your software and the UA-25 to the same sample rate.
If you change the UA-25’s sample rate, you must disconnect the USB cable that connects
the UA-25 to your computer, and then re-connect the USB cable in order for the new
setting to take effect.
Playback/recording stops midway, and subsequent playback/recording is
not possible
Digitally recorded sound has distortion, the wrong pitch, or contains noise
