    Any thoughts or technical experience with these for purposes of comparison? From what I've read about WDM they supposedly give ASIO a run for it's money.

    Well, I'm not a programmer, but it's not WDM vs. ASIO but WDM vs. VXD. An ASIO can be a WDM driver, e.g. the Audiophile driver for Win2k.

    WDM is a new driver architecture for Windows, which allows to develop a driver that runs on Win98 AND Win2k, and allows low latency drivers for windows. It's now possible to get roughly the same latency with MME (windows audio) driver as you can with ASIO or EASI drivers.
    But I think ASIO has still advantages as it has more pro audio features.

    I try to find out more...

    Ok, now I get it, thanks JMX.

    edit: now I'm slightly confused as to what midiman means when they say MME programs, and list restrictions. What specifically are they talking about? I think they mean programs that use MME drivers instead of ASIO etc.?
