Re: Is Logic 101 the only tutorial...
Yes, I see what you mean. I hadn't explored the Electronic template. I have a similar environment (not nearly as extensive)... but you're correct the Logic 105 would probably not help a new user to Logic understand how to unravel this particular environment. But the 105 is part of the level 1 series, it's not designed to be an advanced tutorial.
I think users familiar with the TNT1 and TNT2 will have a better chance of making something similar using Arpegiators and Delay Lines and ways to remote control the different parameters of transformers.
But, this particular example is pretty complex to look at :)
