To add to John's explanation I have BiaB, Realband, Audacity and a couple of media players all on MME. I can run all of them at the same time. I don't but I can. Note that I do not record in RealBand.

I have my DAW, Sonar, on ASIO drivers. Thus I can have Sonar running while BiaB and/or the other MME programs running simultaneously.

I have the stand-a-lone Kontakt on ASIO so I can play sounds on it with no latency. But I can not run stand-a-lone Kontakt and Sonar at the same time. ASIO can only run one program at a time.

As John said "(NOTE: Yes, I know there are workarounds for multi-program ASIO, but they have their own issues)."

I hope this helped.


I got banned from Weight Watchers for dropping a bag of M&Ms on the floor.
It was the best game of Hungry Hippos I've ever seen!
