### Cautions and Limitations

- Sound interruption or other less-than-perfect outcomes may be experienced if your computer's performance and specifications are somewhat inadequate. The types of applications you use and the way in which you use them can also influence the experience you receive.
- If the PC is started up while the OCTA-CAPTURE is still connected to the PC with its power turned on, the driver may not be loaded properly and you may not be able to use the OCTA-CAPTURE. In such cases, connect the OCTA-CAPTURE to another USB port or turn on the power of OCTA-CAPTURE after the PC starts up.
- If the OCTA-CAPTURE does not work correctly after resuming from Sleep mode, you should exit all applications that use the OCTA-CAPTURE, and then turn the power of the OCTA-CAPTURE off and on again.
- If the USB cable is disconnected and reconnected while the OCTA-CAPTURE is in use, or if the power of the OCTA-CAPTURE is turned off, then on again, it may stop operating correctly. If this occurs, after resuming, you should exit all applications that use the OCTA-CAPTURE, and turn the power of the OCTA-CAPTURE off, then on again.
- If your computer was experiencing a heavy processing load, such as when accessing a CD-ROM Drive or network while the OCTA-CAPTURE was being used, the OCTA-CAPTURE may no longer operate correctly. If this occurs, stop the playback or recording, then try starting playback or recording over again. If you are still unable to play back or record, quit all programs that are using the OCTA-CAPTURE, then turn the OCTA-CAPTURE off and then on again.
- Audio clicks and pops may occur during playback or recording if you connect or disconnect other USB devices (such as USB memory) or turn another USB device on/off while using the OCTA-CAPTURE.
- In some cases, you may not obtain the expected level of performance if you're using a USB-connected hard disk at the same time as the OCTA-CAPTURE. Do not use a USB-connected hard disk as the storage destination for the audio that you're playing back or recording.

### About the items in the Settings dialog box

Device Selection
  Selects which unit's mixer will be shown when two OCTA-CAPTURE units are connected.
SAMPLE RATE
  Displays the present sample rate.
  To change the sample rate, select a sample rate from the menu.

  * | During playback or recording, or when equipment is connected to the digital input jack, the sample rate cannot be changed.
  * | If you use an application with an audio equipment test function, after changing the sample rate, carry out a test.
  * | When the sampling rate is switched, a small pop noise may be heard, but this does not indicate a malfunction.

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. (By default, this will be the sixth position from the left.)
  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.

  * Note!
  If you use an application with an audio equipment test function, after changing the buffer size, carry out a test.

ASIO Buffer Size
  This is the buffer size that can be set by the ASIO application.
"Use ASIO Direct Monitor" check box
  Check this if you are using the ASIO Direct Monitor function with an ASIO-compatible application.
"Low Latency mode" checkbox
  This lowers the latency of the ASIO driver.

  * | If you cannot play back or record or if the sound is interrupted, clear this checkbox and increase the "Audio Buffer Size."
  * | Since the latency increases if you are using Cakewalk SONAR in WDM/KS mode, clear this checkbox.
  * | This setting has no effect if you’re using two OCTA-CAPTURE units (VS EXPAND).

"VS EXPAND" check box
  Select this check box if you’re using two OCTA-CAPTURE units.
  If this check box is selected, the status of the connection will be shown.
  If you're using only a single OCTA-CAPTURE unit, nothing will be shown.
  For details, refer to the owner's manual for the OCTA-CAPTURE.
"Match with the ASIO sample rate" check box
  This option matches the Windows sound sample rate, e.g. MME, DirectSound, or WASAPI, with the ASIO sample rate. Select this check box when using an ASIO-compatible application concurrently with a Windows sound-compatible application such as Windows Media Player.
"Default" button
  Reverts back to the default settings.
"Show README" button
  This button displays the README file (this document).
