Here is a run through of the setup for the laser controlled music thingy! This is not how it sounds as it is just ticking over whilst I am filming and when I do play it I only have one hand free!
The basic premise is this; Light dependent resistors (up to 16 of them) are stimulated by lights and lasers passing over them and the change in resistance is measured by an Arduino Mega and sent over USB to a laptop running Window 7.
The data streams are processed by OSC and Max/MSP, converted and sent to a variety of sound sources. A number of controls are mapped to surfaces to allow me to manipulate the lasers over the sensors and to control in real -time a number of parameters such as tempo, timing ratios etc.
This is in preparation for a performance at St Gregory’s Art Centre, St Benedict’s St Norwich on 1st October ’11 (1 10 11) @ 7.30pm as part of the Norwich Sound and Vision Festival!
How was MAX used?
Max is used to read the analogue information coming over a serial port from an Arduino Mega board. It is then used to convert and manipulate the resulting data and to route it to a variety of sound sources. Max is also used to route and sort out a number of controllers connected to the setup.
