Michael,

You mentioned garbled sound. Is it all distorted? Or does it stop and start a lot? Can you upload an example as it may help us determine your problem.

Matt's buffer suggestion is the way to go. In my DAW, Studio One Pro 5, I use a low buffer setting to record. But when I get all of my recording finished and I'm adding effects and such I have to increase those buffers. What are your buffer numbers?

Technically you should be able to run ASIO in BiaB, shut down BiaB, then run RB with ASIO drivers. I run BiaB in MME and my DAW in ASIO so I can have them both on screen and usable simultaneously.

When you are at the checkout line and they ask if you found everything say "Why, are you hiding stuff?"

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