I have to admit, I never read the whole manual.
I just had a look in the beginning to learn the structure, how to load sets, projects and samples and to understand what the different machines are for.
For me the best way of learning was to watch all the tutorial videos on youtube, especially the videos by Secretmusic and then experiment on the OT. Learning by doing.
I just look at the manual from time to time, when I need a certain function.
I never hated the OT, but loved it from the beginning
Sure it’s deep, and there are still many function or ways to handle things, that I’m not aware of. But to have fun with it, you don’t have to learn everything at one go.
But reading the manual won’t hurt for sure
