thanks, Willum
although I understand your point absolutely, and know many have agreed with it, in relative terms, compared to all the other manuals I've read, I still feel that the Technics manuals are among the best.
Without mentioning names I've read manuals that give no idea how a function works without the customary trial and error of pushing buttons until you find the limitations. Alternatively I've had keyboards where I could almost write a book about all the things you could do that are not even mentioned in the manual, just with a little lateral thinking.
I think the difference is perhaps the manufacturer writes an operating manual which by definition assumes you know what you want to do, and tells you how.
Since the days of the Tutorials, which then evolved into magazine Workshops, I write more of a training manual, which tries to explain what is available, why you should use it, and then show how.
The feedback I constantly get is of the type "I never knew you could do that" and "I tried that for the first time and the result is brilliant", and that is the whole point - not to have a closed mind but discover what you can do by trying new things.
