Before you begin

Settings for audio input and output on Mac OS X

  1. Use a USB cable to connect the QUAD-CAPTURE with your computer.
  2. Open "System Preferences" and click [Sound].
  3. Select "QUAD-CAPTURE" for each of the following settings:

Settings for MIDI input and output on Mac OS X

  1. Use a USB cable to connect the QUAD-CAPTURE 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 "QUAD-CAPTURE" is displayed.
    *If "QUAD-CAPTURE" is not shown, or is shown in gray, the QUAD-CAPTURE has not been recognized correctly. Try clicking "Rescan MIDI." Alternatively, disconnect the USB cable of the QUAD-CAPTURE 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 "QUAD-CAPTURE" 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 "QUAD-CAPTURE" in the "Device Name" field.
      *You don't have to enter anything for the "Manufacturer" and "Model" fields.
  7. Using your mouse, drag the up/down arrows indicating the input/output port to make the following connections.
  8. To verify that MIDI transmission/reception is occurring correctly, perform the following procedure.
  9. Click "Test Setup."
    *If a MIDI sound module is connected to the QUAD-CAPTURE, 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 QUAD-CAPTURE's MIDI OUT connector, click the down arrows of QUAD-CAPTURE 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.

Before you use the QUAD-CAPTURE with software

  2. Select "QUAD-CAPTURE" in the audio driver setting of your software.
  3. Select "QUAD-CAPTURE" in the MIDI driver setting of your software.

For details, refer to the manual that came with your software.

About the items in the Driver Settings Panel

"SAMPLE RATE"
Displays the present sample rate.
To change the sample rate, select a sample rate from the menu.
"CLOCK"
Displays the present clock source.
INTERNAL Indicates the internal clock is operating.
EXTERNAL Indicates the clock is operating in synchronism with the equipment connected to the digital input jack.
*The sample rate of the input digital signal is also displayed.
"Audio Buffer Size"
You can adjust the audio input/output buffer size.
Decreasing the buffer size will shorten the latency and improve realtime performance, but might make it more likely that you will experience audio clicks and pops, depending on your computer's processing power and the song data load.
Increasing the buffer size will lengthen the latency, but will make audio streaming more stable, and it will be less likely for audio clicks and pops to occur.
In general, you'll probably want to decrease the buffer size for better realtime performance if you're playing a software synthesizer in real time, or if you're monitoring an audio input that's being passed through your DAW software.
Conversely, you can increase the buffer size to prevent audio clicks and pops if you're recording or playing back song data that contains numerous tracks and presents a heavy processing load.
By changing the buffer size as appropriate for your situation, you can obtain the right balance between realtime performance and audio streaming stability.
 
"Recording Margin"
If the recorded audio data contains sound dropouts or noise even after you've adjusted the audio buffer size in your software and also adjusted the above "Audio Buffer Size," try increasing this "Recording Margin" setting.
*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.
 
Note)
If you click the [Apply] while your audio software is running, the setting changes won't be immediately reflected. Only after all audio software have been quit, and the software is then started once again will the settings become effective.

To uninstall

  1. Start computer with all USB cables disconnected.
    (except the keyboard and mouse)
  2. If the QUAD-CAPTURE Control Panel is running, quit it first.

  4. The display will indicate "This uninstalls QUAD-CAPTURE driver from this Mac."; click [Uninstall].
    *If any other message appears, proceed as directed by that message.

Troubleshooting

Cannot select the QUAD-CAPTURE device

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

No sound is heard; 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 QUAD-CAPTURE. Exit all currently playing or recording software, and disconnect/reconnect the USB cable of the QUAD-CAPTURE.
 
Try adjusting the audio buffer size of the driver
If the size of the driver's audio buffer is too small, sound may not be produced, or it may be impossible to carry out normal playback and recording.
In such cases, you should refer to "To change or verify settings," and increase the size of the buffer.
 
Ensure that the QUAD-CAPTURE and the application are set to the same sampling frequency.
If the sampling frequency settings do not match, error messages may be displayed and recording/playback errors may occur.
 
Are you using a sample rate of 192 kHz?
When running at 192 kHz, the audio configuration is 2-in/2-out.
The remaining channels cannot be used and no sound will be heard.
 

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.
 
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 QUAD-CAPTURE connected to a USB hub?
Try connecting the QUAD-CAPTURE directly to the USB connector of your computer itself.
 
Is a digital signal different from the sample rate selected in the currently-used application being input?
Check whether the sample rate of the equipment connected to the digital input jack matches the sample rate selected in the currently-used application.
 

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.
When equipment is connected to the digital input jack, the sample rate cannot be changed.
In the audio settings of the application, select the same sample rate as the equipment connected to the digital input jack.
