To use your Edirol 2-channel audio interface with Mac OS 9, certain settings need to be made, depending on how you'll use the interface.
Playing System Audio Through Your Interface
If you want to play system audio using the interface, such as when you're using the CD-player application, you must have the Edirol's ADVANCE switch set to OFF.
- Move the ADVANCE switch to the OFF position.
- Disconnect the USB cable
- Reconnect the USB cable.
With the ADVANCE switch off, your USB interface appears in the Mac's Sound Control Panel on the INPUT tab. It won't appear in the OUTPUT tab, but audio will play from the USB audio interface.
Using the Interface with an ASIO-Compatible Program
If you want to use the interface with an ASIO-compatible recording program, the ADVANCE switch must also be turned on.
- Run the OS 9 driver installation program for your interface, found on the supplied CD-ROM disc or downloaded from Roland.
- Drag the files from the ASIO folder included in the driver installation CD-ROM or download to the appropriate ASIO folder for your recording program.
- Move the Edirol's ADVANCE switch to the ON position.
- Disconnect the USB cable.
- Reconnect the USB cable.
- Launch your ASIO-compatible recording program.
You'll now be able to select the Edirol audio interface from the audio devices Preference menu of your recording program.
