Thank you Beagle! I knew ASIO4ALL was a "WDM wrapper," but not necessarily the implications.

So, for sake of understanding, IF BB were ASIO2 compliant, I could run it and Sonar simultaneously with the same sound card using ASIO4ALL, latest version, as long as the soundcard had a WDM driver installed. (Not that I'd want to for serious work. My 2496 has its own native ASIO driver. I was curious because I also have a soundblaster, with which I noodle at the desktop.)

-Thanks again. -Ron
