  1. I can’t help but think of the pranks one could pull; secretly bluetoothing your Apple Watch to someone else’s equipment, then start changing things in the middle of a gig while watching the keyboardist lose his s#$@.

  2. I don’t get the point of this. When would it be useful? A solution to a problem that doesn’t exist – I could use my hands to control the thing this is trying to control (unless e.g., my synth was in a different country).

    1. Maybe for any other instrument that is not a synth and that doesn’t have knobs: guitar, violin, trumpet, LinnStrument, Continuum, Chapman Stick, Harpejji, tuba, acoustic piano, …? Or when actually don’t have a physical instrument but are playing with an iPad or a laptop and you want instant control over transport, volume, sound parameters, … I don’t really think it takes much imagination I think to come up with many situations where a controller on your wrist that is instantly accessible and can be used without holding in your hands, could be useful.
