Thanks folks,
If your audio routing is set up right, what do you need to do before you can hear the Audio thru BIAB? Do you need to press record? I ask because at present nothing is working.
I figured out that if you use MME you cant even see the routings in my system you just get 'Microphone Saffire Audio' which I presume means either the first mono input or stereo pair?
Anyways I have decided to select the Saffire Asio which offers no less that 28 input pairs starting at 0 &1 in BIAB . The Saffire labels these differently - starting at one rather than zero, so I have worked out that the inputs on my saffire (5 & 6) which I have used correspond to 4 & 5. I have set to these.

If I click on the speaker/level icon I get the windows Sound dialogue coming up this has Microphone Saffire Audio come up, but no channels are seen there and no activity is seen on the VU level thing (right hand side of windows SOund dialogue Record tab) even when there is clearly Realtrack sound outputting from BIAB - I can hear it.
If I click on the R.Aud I can see input coming in from the Nord keyboard in the VU meters here, but the output channels remain inactive. I have checked the output ports of the output port windwindow in the BIAB Asio Drivers dialogue, this is corectly set to 0,1.



this is mystifying..

its very confusing.

thanks for the help
