Before you begin

Settings for audio input and output on Mac OS X

  1. Use a USB cable to connect the UA-25 with your computer.
  2. Open "System Preferences" and click [Sound].
  3. Select "EDIROL UA-25 ?? kHz" for each of the following settings:
    (The above "??" depends on the setting of the UA-25's sampling frequency.)

Settings for MIDI input and output on Mac OS X

  1. Use a USB cable to connect the UA-25 with your computer.
  2. In the Applications - Utilities folder, double-click "Audio MIDI Setup" to start it up.
  3. Click the "MIDI Devices" tab.
  4. In the "Audio MIDI Setup" dialog box, make sure that "UA-25" is displayed.
    *If "UA-25" is not shown, or is shown in gray, the UA-25 has not been recognized correctly. Try clicking "Rescan MIDI." Alternatively, disconnect the USB cable of the UA-25 and then reconnect it.
    *If you installed a different version driver, it is possible that the previous settings are still present. If so, click the grayed "UA-25" or "EDIROL UA-25" to select it, and then click "Remove Device" to delete the previous settings.
  5. Click "Add Device." A "new external device" will appear.
  6. Specify the "Device Name" for the "new external device."
    1. Click the added "new external device" to select it, and then click "Show Info."
    2. Enter "UA-25" in the "Device Name" field.
  7. Using your mouse, drag the up/down arrows indicating the input/output port to make the following connections.

  8. < Mac OS X v10.2 >

    Close the "Audio MIDI Setup" dialog box. This completes the settings.

    < Mac OS X v10.3 and later versions >

    To verify that MIDI transmission/reception is occurring correctly, perform the following procedure.
  9. Click "Test Setup." The mouse cursor will change to the shape of a musical note.
    *If a MIDI sound module is connected to the UA-25, the following step will cause a relatively loud sound to be produced by the sound generator, so it is a good idea to turn down the volume on the sound generator first.
  10. If a MIDI sound module is connected to the UA-25's MIDI OUT connector, click the corresponding icon in the Studio Setup window. If you hear sound, the settings have been made correctly.
  11. Click "Test Setup" once again to end the test.
  12. Close the "Audio MIDI Setup" dialog box. This completes the settings.

*For some software, it may not be possible to adjust the buffer size.
 
"Recording Timing"
If the timing of the recorded audio data is not correct, adjust this value.

Troubleshooting

Cannot select the UA-25 device

Did the computer enter a Sleep mode while the UA-25 was connected?
If the computer entered a Sleep mode while the UA-25 was connected, it may not operate correctly. In this case, after resuming, exit all software that are using the UA-25, and disconnect the USB cable of the UA-25 and reconnect it.
 

Cannot playback or record

Could you have entered Sleep mode during playback or recording?
If you entered Sleep mode during playback or recording, it will no longer be possible to play back or record from the UA-25. Exit all currently playing or recording software, and disconnect/reconnect the USB cable of the UA-25.
 
Could the sample rate of the UA-25 be set to a rate other than 44.1 kHz or 48 kHz?
Your software might not support a sample rate other than 44.1 kHz or 48 kHz. If yours is not compatible, set the switch to 44.1 kHz/48 kHz.
 

Occasional disruptions in the sound or noises occur.

Try adjusting the audio buffer size for the software you're using.
First, try adjusting the audio buffer size for the software you're using.
If sound dropouts or noise still occur during playback or recording, try adjusting the "Audio Buffer Size" in the Driver Settings panel.
*For some software, it may not be possible to adjust the buffer size.
 
Try setting "Processor Performance" to the "Highest" setting.
Making the following settings may eliminate sound dropout.
*Some Macintosh computers may not have the "Processor Performance" setting.
  1. In "System Preferences," click "Energy Saver."
  2. Click "Options."
  3. In "Processor Performance," choose "Highest."
 
Could you have performed a Mac OS X software update while the device was still connected?
If you performed the Mac OS X software update with the device left connected, drop-outs may occur in the sound. If this occurs, please re-install the driver.
 
Is the UA-25 connected to a USB hub?
Try connecting the UA-25 directly to the USB connector of your computer itself.
 

Occasional disruptions in the sound or noises are in the recorded audio data.

If the recorded audio still contains sound dropouts or noise even after you've adjusted the audio buffer size as described in "Occasional disruptions in the sound or noises occur" (above), try increasing the "Recording Margin" in the Driver Settings panel.
*For some software, it may not be possible to adjust the buffer size.
