I use the Focusrite Scarlett 18i20 . It has been great with no exception period. BIAB used it fine until I updated Windows. It has the latest drivers and like I motioned My DAW's work fine I use Reaper and Mixcraft 8 I also use Cognitone Synfire Express with no problems. I reinstalled the drivers for the Scarlett and now I'm reinstalling BIAB full installation to see if that helps. I had been using BIAB directing fron the USB hd.
