You can always easily use Audivolv with a mouse. That will always be the main user-interface and it will always work immediately.
Its not easy to set up these experimental hardware connections, but it will get easier as more people do it. Us mad-scientists have to do it first, then automate it and get it ready for use with global AI networks, mass-production, etc.
In later versions of Audivolv (could be years from now), hold 2 Wii controllers (12 dimensions), or 5 people each hold 2 Wii controllers (60 dimensions). Instead of listening to the music and dancing to that, dance to create the music, which will create different kinds of dancing. In that way, you and AI together will create a strange-loop that creates more strange-loops and creates better AI and music software. Theoretically, by using your movements and music as a 2-way communication between people and AI, AI can learn how your unconscious mind works and copy parts of that into new AI software.
Here are some open-source softwares that connect those Wii controllers wirelessly to a computer.

Audivolv does not have to obey the licenses of those softwares for the same reason Audivolv does not have to obey a license for your mouse or keyboard. They are only controllers and no direct software connection is needed. Each Wii controller can detect acceleration and turning in 3 dimensions. Thats 6 dimensions per controller. Future versions of Audivolv will evolve music using many devices simultaneously.
These controllers are normally used with a Wii game system, but open-source softwares can connect them wirelessly to a computer also.
