Ok, so while other things have been working away in the background, I've been slowly watching a Studio One 2 video tutorial, made by Groove3. It's the intro one, not the advanced.
I've already seen one by 'Ask Video', which I do not recommend you get. The presenter seems nervous, unprepared, and quite often his speech is unclear so you don't know what he's saying.
Groove3's though, it's blowing me away. There's 57 video segments that slowly get you into 'just' beginning to to see the tip of the iceberg and comprehend what Studio One 2 is capable of.
The guy who talks you through it is an excellent speaker, nice and clear, unrushed. I don't think I've heard him say one single 'er'. And he knows his stuff, as you would expect. And the video presentation is great too, plenty of zoomed in close ups where necessary.
So if you're looking for some good 'invaluable' help, go get Groove3 - Studio One 2 Explained
