You can`t feel the positions of the knobs on any of your kit unless you look at it.
If you blindy reach for a nob on a synth, unless you remember where you set it last or are looking at it, then you won`t know where it is.
So in actual fact with this kit, you are turning knobs.
They are solid objects, that you turn physically, that also have a visual reference.
How can they be any more knobby?
I totally don`t get your point.
What you are seeing in that video is the beginning of the future.
