Dan all this looks very interesting and certainly a viable choice as variation to using a stand alone arranger. I am looking at all avenues and alternatives to what i am now using.
Of course i have concerns and different needs then other people and many questions about setting up a rig as shown in your website pictures also. When I get a chance I'll email you with some of my questions to get an idea of what is entailed in using the Varranger software for gigging.

Thank you
