Are you using ASIO drivers for both? ASIO will only handle one application at a time. I use ASIO for Sonar and MME for BiaB and everything works fine.

Also MME for both BiaB and Sony Acid should work.

I hope this helps.


OK, a random thought;
Why does toilet paper need a commercial? Who's not buying it?

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