M-AUDIO xSession Pro 사용자 설명서

-Session  Pro  is  a  professional-quality  controller  that  has  been  tested  under  a  wide  variety  of  conditions.    Despite  our 
thorough testing, X-Session Pro can be used in nearly limitless situations and certain scenarios may result in unexpected 

performance.  This section will highlight some of the most common difficulties users may experience and provide tips to remedy 
these problems.  

First and foremost, we recommend that you avoid connecting several USB devices to the same port on your computer.  While USB 
is a dependable protocol that is well suited for audio applications, it is important to remember that audio and multimedia applications 
place considerable demands on your processor and the USB bus. Although it is theoretically possible to connect numerous devices 
to one USB port, doing so may cause complications with your hardware and software.

  Verify that the X-Session Pro drivers are properly installed.

 

•

  

In Windows XP, go to the control panel and double-click the System icon (under Performance and Maintenance if you 
are in Category view).

 

•

 

Select the Hardware tab and click the Device Manager button.

 

•

  

Click the plus sign (“+”) next to Sound, Video and Game Controllers, and locate the “X-Session USB” and “X-Session 
MIDI” or “USB Audio Device” listing. If you see a question mark or exclamation point next to either the X-Session 
USB or X-Session MIDI listing, you nay need to reinstall the driver software.

 

•   If you are using X-Session Pro as a class-compliant device and you see a question mark or exclamation point next to a 

“USB Audio Device” listing, disconnect X-Session Pro to see if this item disappears from the Device Manager window.  
If it does disappear, try connecting X-Session Pro to a different USB port to see if this resolves the problem.

<

   Make sure your DJ or audio application has been set up to use the controller.  Open your application’s control panel 

and verify that the software is configured to receive the MIDI data generated by X-Session Pro.

<

  Double-check that your USB cable is properly plugged in.

<

  If you are using a USB hub, try connecting X-Session Pro directly to your computer.

<

  Make sure your input and output levels are not too loud, as this can cause distortion and clipping.

<

   Try  increasing  the  buffer  size  of  your  audio  interface.    Larger  buffer  sizes  will  result  in  higher  audio  latencies,  but 

will improve system performance and resolve many clicking and popping issues.  Consult your audio interface or DJ 
software’s user guide for more information about this.

<

   If you are using X-Session Pro with another USB audio interface and are experiencing clicks and pops, try disconnecting 

X-Session Pro and see if it improves your situation.  If so, reconnect your X-Session Pro to a different USB port on 
your computer and make sure that X-Session Pro and your USB audio device are internally connected to separate USB 
controllers (i.e., they are not sharing the resources of one controller).

<

  Make sure all your audio cables are in good working order and are properly connected.
