Conversely, if you’re recording or playing back song data that contains numerous tracks and imposes
a heavy processing load on your computer, you should increase the buer size in order to decrease
clicks and pops.
Change the buer size as appropriate for your situation in order to achieve a balance between
realtime response and audio data transfer, while avoiding problems such as clicks and pops.
* If you’ve changed the buer size, you must restart the software that’s using the OCTA-CAPTURE.
Alternatively, if you’re using software that has an audio device test function, execute the
software’s test function.
* Depending on the software you’re using, its audio settings may also have a buer size adjust-
ment.
“Use Multichannel WDM Audio Port” check box (Windows XP)
If this check box is selected, you can use all audio channels via one WDM audio port.
Check this if you are using Cakewalk software, such as SONAR, with WDM/KS mode.
* The modied setting will take eect after you turn the power of the OCTA-CAPTURE on/o.
* If this check box is selected, you cannot use the WDM audio ports as 2-channel (stereo) audio
ports.
“Use ASIO Direct Monitor” check box
Check this if you are using the ASIO Direct Monitor function with an ASIO-compatible application.
“Reduce CPU load” check box
This reduces the load on the CPU when the ASIO buer size is small. If you experience clicks or pops
with a small buer size, selecting this check box may help.
* If you are still unable to play/record, or if you still experience clicks and pops, clear this check box
and increase the “Audio Buer Size.”
* If you’re using the OCTA-CAPTURE in WDM/KS mode, leave this check box cleared.
* This setting has no eect 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.
Show “README”
This displays the online manual for the driver.
Setting the sampling rate
The sampling rate setting of the OCTA-CAPTURE automatically changes to match the rate of the
audio data that is played, or the rate that your DAW software is set to when recording.
