Neil,

The WAS driver reduces latency. Like many ASIO drivers, though, it can be a 'one audio program at a time' scenario in that if you have WAS in BIAB and that has the focus, it's more than likely you won't hear anything in Reaper.

There have also been a few instances on the forum here where WAS hasn't played friendly with BIAB.

If you don't play directly through BIAB and so latency is not an issue, I'd stay with MME. (That's what I use.)

Regards,
Noel
