People do learn in three primary ways. The
visual and manuals are good for these. The
auditory, good for listening and the
physical experience. Actually doing the stuff and having someone sitting next to them being shown and then they do it etc.. I have had a few private students that preferred the visual. Although they had access to all the manuals, they needed to be shown etc.. So I guess the manual readers are only going to fall into one third of everyone which is understandable. Some can learn with more than one approach as well.
I had to do an Avid training course once and that was a physical experience. We all sat in front of a Pro Tools session and the instructor showed us how to do stuff. Then we had to do it etc... It was good but it was also backed up with written material. If there ever was something that really uses the manual it is Pro Tools. The manual is huge.
But yes, a manual can unlock something indeed. Watching a video though is more a visual as well. It's good to run a visual, say a video on one machine (laptop or iPad) while using your main machine next to the visual teaching machine e.g. combine visual with physical. You get a double pronged approach.
There is so much to learn now. I could spend a year learning about Yamaha Montage for example or my Kurzweil workstation.
I don't think you can fumble around so much these days though and discover things. In the old days there was much less to discover. Now the amount of stuff something can do is almost limitless. I don't mind
Mr Manual. It's late night reading for me.
