This is like a parody of innovation! It looks like a concept project mostly. The key to making anything like this comes from how well it is integrated with the software, and audio production software is really hard to get right.

There is a need for physical controls for music software control (or any software) and there is a fundamental problem. The amount of parameters and functions that need to be controlled is vast. It will quickly overwhelm a control surface with limited amount of controls unless a lot of thought and design is put into the a method of switching the function of the controls. These types of controls are still virtual!
