SuperCollider

supercollider showcase (August 2016, when the groups were killed - 2014)

Some time ago a did a thing on a series of numbers ( https://soundcloud.com/henklasschuit/discovering-supercollider03 ), that, as I learned later, was officially called the Collatz problem and it can be found on the Online Encyclopedia of Integer Sequences: http://oeis.org/A070165 . One day I was playing with those numbers on a keyboard and I had the impression, that some notes occur more frequent than others. This implies some kind of tonality. So I rewrote the code to use notenumbers in stead of frequencies. And here is the result. The fourth step, which coincidentally is a C, is dominant and the 10th, F# follows. There is quite some A, B flat, C#, E and G and very little E flat. A flat, B, D, and F are almost absent. So I guess the Collatz scale is: C, C#, E, F#, G, A, B flat, C and you can use E flat as some kind of Blue note or something.

Екатерина Брындина - "Замок пустых ручьев"

This album is inspired by a painting by Giovanni Battista Tiepolo. Every sound is created randomly using a computer language named SuperCollider and processed through a software called Kaleidoscope.

Desert data

A thunderstorm, made with SuperCollider. There are three layers of sounds: rain, wind and thunder. 
There is a global envelope controlling the density of the raindrops and the thunder as well as the frequency of the wind. For the rain there are ticks of noise, but also a few drops falling on metal objects. I like that sound. 
For the wind there are two identical functions, one plays in the left channel and one plays right. Thunder is the most complicated of them all. It is filtered noise with a slow trigger for making a thunderclap and a fast trigger for the rumbling within a thunder. I added some FreeVerb to make it more spatial.

Discovering SuperCollider02: Thunderstorm

Imagine a box that is divided into smaller compartments. You start randomly throwing beads (or marbles or grains) into it. Wheneven one compartment is full, you stop. Check how many beads there are in a compartment whenever a bead falls and check the distribution of beads in the box after you stopped. Turn numbers into pitches. Or show numbers as ASCII-characters. For the latter you need to run the code in SuperCollider. The code is available at http://sccode.org/1-31X . For the complete experience you change maxValue to 255 and  you remove '+32' where shown.

Discovering SuperCollider04: Confetti2

Yeah, let's do the Bell Thing! The Bell Thing was inspired by an experiment that my brother did on his sampler, holding the keys down with boxes of musicassettes. Sounds great, looks ehm... interesting. There are several reasons to do this. First of all I definitely wanted to do The Bell Thing in SuperCollider. Furthermore tomorrow is my mother's 86th birthday and I was wondering if I could make a computercomposition that she would enjoy listening to. And finally it can be done with a tiny amount of code, so it could be a SCtweet. Here it is:

for(1,16,{arg i;{Pan2.ar(VarSaw.ar(50*i,0,0.35,EnvGen.kr(Env.perc(0.01,16/i),Impulse.kr(i/32,1.0.rand))/i),(-1**i)*i/16,0.25)}.play})


The Bell Thing

Remember Confetti 2, https://soundcloud.com/henklasschuit/discovering-supercollider04 ? There you heard only one oscillator at the time. In SuperCollider it is easy to use 100 oscillators at the same time, so while a distribution is made, you can hear sounds that correspond with all the values in the box. That doesn't swing at all, instead it gives a kind of Xenakis-like experience.

Confetti2X

The search for prime numbers from 1 to 100 is represented by sound. Channel 1: the numbers, channel 0: the divisors. In the center: a fm-sound with a carrier that is related to the number and a modulator that is related to the divisor. A harmonic sound means the carrier is a multiple of the modulator, so the number is a multiple of the divisor. Therefor a harmonic sound means: not a prime number. When a new prime number is encountered, the list of prime numbers is played.

The quest for the prime numbers

There was a time when I was involved in Science! But that was a mistake. My Passion is music. I play the pipe-organ and synthesizer, I play the organ in a few bands and I like Apple computers. I discovered SuperCollider and VCV Rack: great ways of making sounds. Enjoy them on SoundCloud!
