### Cautions and Limitations

- Before you start up your sequencer or related software, use a USB cable to connect the STUDIO-CAPTURE to your computer and turn on the power of STUDIO-CAPTURE.
- Do not turn off the power of the STUDIO-CAPTURE or disconnect the USB cable during playback or recording. Doing so may cause your software or operating system to shut down abnormally.
- You must first exit your sequencer or related software, and then switch off the STUDIO-CAPTURE's power or disconnect the USB cable.
- You must disconnect the STUDIO-CAPTURE from the computer before performing a software update for OS X. If you performed the OS X software update with the STUDIO-CAPTURE left connected, you will need to re-install the driver.

2. The "STUDIO-CAPTURE Control Panel" will appear.

## To change the settings

### To change or verify settings

1. Use a USB cable to connect the STUDIO-CAPTURE to your computer and turn on the power of STUDIO-CAPTURE.
2. Open the "Applications" folder, and double-click "STUDIO-CAPTURE Control Panel."
   The "STUDIO-CAPTURE Control Panel" will appear.
3. From the "STUDIO-CAPTURE Control Panel" menu, choose "Driver Settings..." to open the "Driver Settings" Panel.
   The Driver Settings Panel is displayed.

### 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 STUDIO-CAPTURE Control Panel is running, quit it first.

Follow the procedure described below to start the application.
  1. Hold down the Control key and click the icon of the application that you want to start.
  2. On the menu that appears, select "Open."
  3. When you are prompted to confirm that you want to launch the application, click "Open."

     * | Once you follow the procedure above, you can start the application by double-clicking its icon.

### Cannot select the STUDIO-CAPTURE device

Did the computer enter a Sleep mode while the STUDIO-CAPTURE was connected with its power turned on?
  If the computer entered a Sleep mode while the STUDIO-CAPTURE was connected with its power turned on, it may not operate correctly. In this case, after resuming, exit all software that are using the STUDIO-CAPTURE, and then turn on the power of the STUDIO-CAPTURE once again.
If you start up your computer when the STUDIO-CAPTURE is already powered up and connected to your computer, the driver might not be loaded correctly, causing the STUDIO-CAPTURE to be unavailable for use.
  In this case, try connecting the STUDIO-CAPTURE to a different USB port, or turn on the power of the STUDIO-CAPTURE after your computer has started up.

### 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 STUDIO-CAPTURE. Exit all currently playing or recording software, and switch the power of the STUDIO-CAPTURE off, then back on again.
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 STUDIO-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 8-in/4-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 OS X software update while the device was still connected?
  If you performed the 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 STUDIO-CAPTURE connected to a USB hub?
  Try connecting the STUDIO-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.
