Roland Edirol UR-80 Mode D'emploi page 377

• Does your computer satisfy the requirements of the USB standard?
If you are using a computer (such as a computer that you yourself assembled) that does not satisfy the
electrical requirements of the USB specifications, you may experience interruptions in the audio. If this
occurs, you may be able to solve the problem by connecting a USB hub that contains its own power supply.
• On some computers, audio playback may be interrupted due to the Power Management
settings in the Control Panel. (;only Windows user)
The Power Supply Properties that you see when you double-click Power Management will differ
depending on your computer system. One example is given below, but you should also refer to the
operation manual for your computer. Some computers may not have all of the following setting items.
1. Click the Windows Start button, and select Settings | Control Panel to open the Control Panel.
2. In Control Panel, double-click System to open the System Properties dialog box.
In Windows XP, click Device Manager in the Hardware tab.
3. Click the Device Manager tab.
4. Double-click System Devices to display the list of devices.
5. From the list, select Advanced Power Management Support. Then click Properties to open
the Advanced Power Management Support Properties dialog box.
6. Click the Settings tab, and in Troubleshooting, place a check in the check box for Don't Poll
Power Supply Status. Then click [OK].
7. In the System Properties dialog box, click [OK].
8. Restart Windows.
• You can solve this problem in the "EDIROL UR-80 Driver Settings" dialog box.
For details, refer to the section "Something is wrong with playback; sound is interrupted or notes are
missing" within the Readme_e file located in the folder in which you installed the CD-ROM.
• Depending on the virtual memory setting or network-related settings, noise may occur.
Please make the following settings before use. (;only Macintosh user)
1. 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".)
2. In the "Memory" Control Panel, set Virtual Memory to "Off".
3. Depending on the way in which you connect to the Internet, use the UR-80 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.
