Many years ago in 1990, Bob Turner and I, Jeff Koftinoff, were working on alternative MIDI input devices at Simon Fraser University specifically for high level quadriplegics.

During our work at S.F.U., we came across a video for MIT Medialab's "The Digital Baton". In the video that we were shown, one person "conducted" a MIDI sequence playing on a computer with a large baton, while another person played along with a violin.
