Graham, exactly what is your setup? Are the audio mics or are you recording directly from the Yamaha to your computer? Or are they USB mics? The reason I ask is because it makes a difference. If it is USB then maybe Window is turning those ports off. If it is audio then maybe either Windows or your DAW/BiaB is loosing the connections.

If you are using audio mics then I would ask why?


I think my wife has started to show the first signs of dementia.
She said she can't remember what she ever saw in me!

64 bit Win 10 Pro, the latest BiaB/RB, Roland Octa-Capture audio interface, a ton of software/hardware
