Thanks, Mac. I missed PG's references to this development path. I'll have a look at Bootcamp and Parallel - the name "Bootcamp" implies a dual-boot set-up, which I'd rather avoid. I've been using Ubuntu as my main operating system for the last couple of years, but can't get satisfactory audio performance using BIAB with Wine or VirtualBox - I have to boot up a "real" version of Windows to use BIAB.
