[Noah] tipped us off to his work with physically Engaged electronic Instruments. He is building instruments, that while being electronic, need physical action to drive them. In the video after the break, you can see an example, in the type of a polka. The part that they’re holding (print head?) is connected to a generator which powers the instrument. The impact makes the instrument much much more like a conventional stringed instrument that should be strummed. We can quickly likewise picture an interface similar to a concertina or accordion being functional. There are schematics offered on his site in the research study reports section, however you’ll have to dig with a pdf or two to discover them. We would like to see a breakdown of the instruments as well as their elements in a much more available form.
