More ways to shape your music
Compose from a preset or a sentence, write music as code or play a keyboard, then read, search, paint and share it.
Write, hear, change
Live coding
Write notes, chords, loops and parallel parts with play, sleep and tempo. Formulas can become melodies too.
Write your first phraseChoose your sound
Built-in synths & samples
Use sine, saw, square or triangle waves, or play built-in and your own WAV samples with sampler().
Explore sounds and samplesCompose with rules
Algorithmic composition
Set a key, a contour and rules for lengths and leaps, then generate a phrase into Code.

Shape and editAdd instruments and effects
VST3 plugins & manager
Scan your VST3 folder once, then chain up to four instruments and effects in each code window.
Manage your pluginsConcept
Live coding
Write notes and their timing, and hear your code played as music.
Algorithmic Composition
Generate phrases from your own rules: a key, a range, a contour and limits on rhythm and leaps.
Data-Driven Method
The built-in models learned from thousands of songs. Give them a word or a sentence, or retrain them with your music.
Story
Live coding
“Live coding” is an intriguing phrase. Programs can be huge or critical, yet making coding live means the joy of typing words and hearing them come alive at once.
Cogitsune Music began with a simple purpose: to let people enjoy writing code through music.
Calculation and Algorithm
A computer calculates numbers and conditions at astonishing speed, and music is made of conditions: rules and structure combined with freedom.
So why not calculate them to make music? Join the long tradition of computing music.
Data-Driven Method
Today computers can learn from data itself, so the data you create can be learned too.
Here you can see what a model learned from, add your music and build your own learning machine.

Message From Creator
Thank you for taking a look at Cogitsune Music. I'm Gounbeee (goh-un-bee).
“Cogitsune” combines the Japanese “Ko” (child) and “Kitsune” (fox), spelled to bring to mind the Latin “Cogito” (I think), or so I hope!
As I write this in 2025, I believe non-human agents will handle more and more of our data. Even as change speeds up, people will still ask, “So what should I do next?”
At that point, in my view, the “value of the individual” will be questioned more deeply, and one day we may realize, “I, as a person, mattered much more than I thought.”
We often live as part of large organizations, for safety, for efficiency or simply because it is the norm, and that is fine. Still, doing as much as we can as individuals matters to those groups too.
That is why building this software and selling it myself is, for me, a meaningful form of personal expression, and why I made this place to connect with each customer.
Cogitsune Music is a Windows app, and I will keep adding updates and tutorials. Many ideas are experimental and things may change a lot, but I’d be very happy if you watched this project grow.
