Has anyone tried BRP-PACU, an open source package that runs on linux and OSX. From the doco it will plot source independent transfer functions.
I attempted to run BRP-PACU on the Ubuntu 11.10 standard distribution a year or more ago. I had a bunch of trouble getting some of the prerequisite libraries installed. Never even tackled the issue of getting my ASIO interface running.
IIRC, the developer was reachable by email. I'd be definitely be interested to hear if you get it running, especially if you have a linux distro it will run inside easily!
