It's pure logic. The difficult part is knowing the symbol names and what each one of them do, the rest is ifs and thens. Watch some tutorials, and refer to the help files. they are very self explanatory. in my opinion, the most time consuming part is VTpro. it's nearly impossible to do it without an extended desktop with 2 monitors. it will take you forever to link join numbers.

The beauty of it is that once you understand how it works, you can do whatever the hell you want. No other system (other than savant) will let you do that level of customization.
