Following initial tests with light sensor types (diodes, transistors), we wanted to make a start in experimenting with the different parameters the light sensors can control. So far pitch and tempo have been the areas we have predominantly focused on in terms of light manipulation. With these experiments we were testing how light may control the length of decay of a tones or tones and if light could control the amplitude through a control voltage. The final video and sound clip are three new machines playing together with gesture controlling amplitude and note decay.
