Yeah if anything it shows that the concept isnt so out of reach, its just the refinement in execution, manufacturing and software.It looks interesting - I am not sure it's as refined as the actual S3XY knob, but for that price it's worth a try.
My S3XY knob (genuine) should be delivered this month
As for the stalks....pfft, what are stalks again? .
I dont think i even need the cheaper version still, but might give it a go for giggles
