there are other tutorials for other softwares, and all the softwares are pretty similar in principle. I have a technical background but to be honest once the router setup was done, and some basic terminal knowledge is there, I found that all the audio routing stuff was only as difficult as e.g. learning how to use Logic and route things to your audio interface in the right way. Once you grasp what the inputs and outputs in Jack are and where signals are going, it becomes clear.
I'll be keeping up with this field a bit in a sort of journalistic capacity, and will soon have an article on the ISM site where I interview a few of the software developers involved. Keep an eye out and I'll try to remember to post an update here too.
