Hej Bumblebee, thanks for sharing your thoughts.. its the criticism that sports innovation. I'd love to hear more. Still I have a slight feeling that you see the FlexiKnobs as yet-another-mouse. Actually they're not.. it's the software that makes the difference.

First of all simultaneous interaction using more than one knob works like on any standard MIDI controller.

Also, the input from each knob can be mapped to a variety of control messages, MIDI, OSC, Keystrokes, u-name-it.. and yes: mouse events too. One could just assign the knob to a given parameter and keep that assignment forever. However, it is also feasible to simply switch between several mappings for each knob, do standard MIDI-learn, or use the ubiquitous point-and-klick interaction to reassign. So flexibility is really the key. But behold: this will never replace the dear MIDI-controller and it was never meant to do that. It is simply just another way to interact with audio software in a way that is just not possible on a touch screen.
