Starkeeper & Scott as you know my software arranger of choice is Live - Styler. I have been able to get it to work but you do have to pay close attention to the input/output ports. This is where I have had most of my problems but once it is up and running it runs flawlessly. I use it for live performances.
Jammer Live is a very worthy alternative. I like the others given there are so many styles available. Plus there is so much software out there to manipulate such styles.
I also serve as a beta tester for Live - Styler, OMB, forte Ensemble and others.
