Lots of good information on Turing Machine here:

Pamela’s New Workout does provide a source of random but it is really meant to be the clocking heart of a system with several other modulation functions and even basic quantization. It is “menu divey” but fast and intuitive. Again, an entire system can be powered by PNW. In my own system, I use it for roughly 80-90 percent of patches, either as a main clock source of source of modulation.
Go slow. There’s lots to learn. About now, I ask: do you have a good quad VCA and do you know how and why to use it?
