CLICK AND DRAG THROUGH THE ARROW AND DISCOVER A MELODY :)
I joined the SinewaveSignal and Pixelarray examples.
I used HUE function to extract the color data.
The palette at the botom is the musical scale I calibrated maping colors an freqs.
This calibration is arbitrary: red is C? G is yellow?
You can change the code to match different notes to other colors.
Thanks and credits for their help to Victor Gil when joining both codes and when searching the variable of the color in Pixelarray: aPixels[int(signal)]
