Hello

What is the difference between asio and wdm ?
what is pro and con from both ?

ASIO is used best with time code solutions. I use my RMX in WDM mode. Reason being it works with Skype, and I use Skype for my web-radio show.
 

Asio offers better latency but uses more resources. Asio is perfect for controllers where button presses can be translated to the software in a few milliseconds.

WDM generally has latencies of 30ms plus, but doesn't require specific hardware and will run on pretty much any PC. Most inbuilt PC cards are WDM or directsound.

I would suggest Asio for controller or timecode use but it will depend on your machine as to whether it runs well or not.
 

one thing i need from asio is my headphone PFL from rmx.

Is there a way to get pfl headphone with asio ?
 

WDM (Windows Driver model) is the standard used by Windows for multimedia applications (playing MP3, movies, etc). It originally allowed 1 input and 1 stereo output (remember the first SoundBlaster cards ???)

In order to bypass this limitation, Steinberg (of Cubase fame) came up with the ASIO driver:

In VDJ, any Multichannel soundcard (i.e. that as at least 4 outputs) will allow headphone PFL. Remember that the Rmx , and other DJ soundcards , were designed for DJ applications, so it wouldn't make sense if headphone PFL was not availalble...
