Live coding
Write notes, set their timing, and hear your code performed as music. Build chords, repeat a phrase with loops, or combine parallel parts.
Start with a short example, then change the pitch, rhythm and sound while exploring how each command works.
Algorithmic Composition
Generate phrases from your own rules: choose a key and pitch range, draw a melodic contour, and control note lengths and rhythmic spacing.
Limit repeated notes or large leaps, then bring a result into Code to play and refine it. No model training is needed.
Data-Driven Method
Collect phrases from Code or MIDI in reusable datasets. Label your music and use your own examples to train a VAE or Transformer.
Explore new phrases with a trained VAE, or turn a word into music with the Transformer. Bring the results back to Code for editing.
Story
Live coding
"Live coding" is an intriguing phrase. In the world of programming, some projects can grow to an enormous scale, while others are so critical that even the smallest error could be dangerous.
So what does it mean to make coding live? It is the joy of using your own hands to type words and instantly bring them to life through execution.
Cogitsune Music began with a simple purpose: to let people enjoy the act of writing code through the medium of music.
Calculation and Algorithm
Programs run inside the machine that processes them—the computer. At its core, a computer is a device built for calculation, capable of performing operations at astonishing speed. Not only numbers, but also various conditions can be calculated.
Music, too, is created under many conditions. Rules and structure, when combined with the freedom that naturally exists, are what make music possible.
So, can we not calculate these conditions to create music? Experience for yourself the long tradition of computing music.
Data-Driven Method
In the 20th century, with the birth of fast, electrically powered computers, technology that allowed machines to learn began to develop. Now, computers can even calculate how to learn from data itself.
This means that the data you create can be learned by a self-learning computer.
With Cogitsune Music, you can experience this process firsthand—creating, collecting, and managing your own data, and using it as the foundation for your very own learning machine.

Message From Creator
Thank you for taking a look at Cogitsune Music. I'm Gounbeee (goh-un-bee).
"Cogitsune Music" is a word I made by combining "Ko" (a Japanese word meaning "child") and "Kitsune" (the Japanese word for "fox"), and then tweaking the spelling so that it also brings to mind "Cogito" (Latin for "I think") – or at least, I hope it does!
As of 2025, when I’m writing this, I believe that non-human agents will play a bigger and bigger role in how data is handled. Even if we reach a time when data is processed much faster and change happens even more quickly, I think people will still find themselves asking, "So what should I do next?"
At that point-and this is just my personal view-I feel that the "value of the individual" will be questioned even more deeply. As we exist as individuals on the internet and in society, I have a feeling that one day we’ll realize, "I, as a person, actually mattered much more than I thought."
These days, for all kinds of reasons, we tend to exist as part of large organizations. That might be for safety, for efficiency, or simply because that’s the norm. There’s nothing wrong with that. But even so, I believe that each of us doing as much as we can as individuals is, in the end, also something very important for the groups we belong to.
That's why I believe that creating software and handling all of its sales by myself is a meaningful form of personal expression. And because I believe it's important to build a personal connection with each customer beyond that, I decided to create this place.
Right now, Cogitsune Music is available as a Windows application, and I plan to keep adding updates and tutorials little by little over time.
Because I'm trying out a lot of experimental ideas, there may be times when things change quite a bit, but I'd be very happy if you could kindly watch over this project as it grows.
