I think he is not looking for how to edit but how to use MC. Kevin P’s free ones are really good. Also Class On Demand has a series for FCP(not X) editors that is pretty good. I have a subscription to that.
Also, as you may have seen, Kevin P. is doing new ones for the upcoming 4K Avid release. The official Avid books are pretty good but since the 4K update is due by the end of the year, they will be out of date soon.
Welcome to the world of Avid. A bit frustrating for FCP editors at first but if one learns the keyboard shortcuts and makes their own, one can be fast. And for me the forced organization of media is a plus.
Hope that helps,
Robert
