On Vision Pro you play it in the air with your bare hands, no controller: pinch a fingertip for a note, raise your hand for volume, push forward for brightness, and move sideways to bend.

Touching your thumb to a fingertip plays a note in a scale and releasing it stops the note, turning your palm reaches the rest of the scale, and while a note plays you raise your hand to make it louder, push forward to make it brighter, and move sideways to bend the pitch.

I'm really excited about what my RouteMIDI tool allows through its MCP server, integrated into Claude Desktop. You can just talk to the LLM to connect MIDI devices together and manipulate their MIDI streams. You can find out more about RouteMIDI here: github.com/gbevin/Route...
