While we are on the subject. Best for you to know a bit more.

If you have an ASIO driver, it likely came from one of two places, 1) it was installed when you setup you sound device or 2) you downloaded and installed ASIO4ALL the free version.

As Noel pointed out if you play a keyboard with (Thru) BIAB while it is playing, then you absolutely need ASIO. The latency (delay) will kill you otherwise.

So why don't we just always use ASIO. Well, main reason is that to just "play" BIAB you don't need it. Furthermore, only 1 program can use ASIO at a time. Many of us use ASIO with our DAWs (because we record instruments), therefore BIAB would not run at the same time if it only had ASIO. So we put BIAB on MME and our DAW on ASIO and now both programs can run at the same time.

There is another reason to be wary of BIAB and ASIO and that is issues with compatibility. Not all ASIO are the same and BIAB has been known to have troubles with some. My MOTU Audio Express ASIO driver runs great with BIAB by the way.
