I always get into the contextual view by accident too when nearly automatically trying to unfocus a control by pressing the softbutton I pressed to focus it before.
Also the view often changes then and the same button formerly used to focus a control now gets a new function, e.g. on the sample player. When you automatically press it again you do something on the sample player like deleting slices.
Also when I am scrolling through a chain and altering things here and there I repeatedly change values instead of scrolling left or right because of this behaviour.
I think I find the new way less intuitive than it was before. I worked with it on a daily basis over 2 weeks now and it still continuosly breaks my flow and makes me feel unpleasant. Which is a shame because apart from that I really find the workflow very intuitive and was able to build nice patches just from having watched some tutorials last fall before ordering one.
I think pressing ENTER would be a great solution to get into contextual view and if I could vote I would vote for using the M buttons only to focus and unfocus. It is like opening a control versus just adjusting it and ENTER is a great button for for something like this.
Comparing to the ER-101/102 the graphic interface is very different and there are a lot more buttons - to me the focus press concept does not seem to be needed and useful here.
