Thanks southpaw.
I've had no luck trying to route audio from Sonar into Mixbus "in-the-box". I ended up downloading a separate Jack-only install (Jack_v1.9.9_64_setup.exe) which gave me the "Jack PortAudio" and "Jack Control" applications which didn't come with the Mixbus download. (Unless I missed something? Did you have to download and install Jack Control separately too?) However I still cannot get Sonar to recognize any Jack/Mixbus ports and vice-versa.
Hmm, I'm just now wondering if I need to use the 32-bit version of Jack since Mixbus is 32-bit. I thought I'd need the 64-bit version of Jack Control since I'm using 64-bit SONAR X3, but maybe that's not the case. I'll have to try out the 32-bit version of Jack when I get back to my DAW.
In the meantime, any suggestions, hints, or step-by-step instructions would be greatly appreciated.
