Re: DIM PRO: What is the best tutorial to learn the advanced controls?
Aside from the documentation included with the synth, the best resource is Simon Cann's book "Cakewalk Synthesizers: From Presets to Power User—Second Edition." It covers all the synths except the Rapture Pro/Session.
There are a variety of resources available on the web regarding sfz files. Most of that data is relevant to DPro.
