By the way, ASIO4All and other universal drivers wrap windows drivers and DirectX drivers to make them ASIO compliant .... but do not be fooled ..... this will NOT get you better latency .... you need to have a soundcard with native ASIO driver. Most devices are nowadays, so this should be easy enough ......
Thanks for all the suggestions, everyone. Yeah, I tried ASIO4All on my MacBook and it blew chunks. Much slower than the original DirectX drivers. I have ordered an Echo AudioFire 4 and will see how that goes.
