This is a demo from a work in progress version of my software that makes sounds, music and noise called DIN Is Noise. I've been working on this software for the last 11 years.
To make a sound or note of music we make a waveform, say a sine waveform, vibrate it at the frequency of the note, convert it to numbers and then send them fast to the sound card that moves the drivers of your headphones [or speakers] and you interpret that movement as this sound or note. The frequency of the sine waveform is its first harmonic, 2nd harmonic is twice the frequency, 3rd harmonic is thrice the frequency and so on. They can be mixed together to make different colors of sound. Here I hand paint the strength of harmonics and let a script inside DIN change them while the balls of Mondrian [an instrument in DIN] where balls bounce in boxes and trigger notes when they hit walls or ceilings.
You can download an evaluation version of DIN Is Noise.
It would be great if you can upvote this post and support my independent research & work on DIN.
