This was quite a cool show in the end. Nick and I used tiny wireless motion sensors attached to the bells of the instruments to control laptops, that were putting effects on our sound. We used clip on mics, and different effects were trained to different positions in space. When I pointed the bell down, the computer would add a note 1 octave down, while also randomly fragmenting the sound and adding different amounts of delay. It made for some pretty hip sounds – especially when I played multiphonics. Then if I pointed the bell up it would create a different effect without the added octave and not as much delay. The computer (Dan and the laptop orchestra were sorting this stuff out for us) also reacted as you moved between positions.
