SORTED. OK I finally have the solution. Its very simple.

I needed to untick the "ASIO always on" box, and its all good. I guess with this ticked Biab has ASIO as exclusive - but still doesnt explain why i have probs when running the other App with non
ASIO drivers.

Anyhow I'm done. Maybe this will come in useful for someone else.

Sorry for hogging the forum - I'll never darken your doorstep again ..... well not for a while.

Many thanks
Tom
