Josh and Ray Gardiner are currently working on a solution on how to light up the Klangwolken ABC during the voestalpine Klangwolke and they’ve come up with a pretty clever solution.
Marco Palewicz, Josh Gardiner, Chris Bruckmayr and Ray Gardiner at the Futurelab
The idea is quite simple and awesome: Take the information that is inside the audio of the Klangwolke and turn it into midi-signals which then control the LED-letters. Those informations can be amplitude, or frequency, or even combinations of various parameters. So, according to what’s going on in the music, the letters are turned on and off.
A nice place to tinker
This on and off can happen according to the pulse or tempo of the music, but can be more complex, as well, for example, the rising amplitude is synchronised with a on/off-pulse that gets faster the louder the music gets. The receivers in the letters even have audio-outputs, so you could create an perpetuum mobile of sorts by feeding the audio-output from one letter into the midi-conversion of another.
This is going to look great at the Donaupark, when thousands of letters will be flashing in sync with the music. Try not to miss this![:]
