Crafting Delightful Digital Experiences
Arbit is a one-person project. It is designed, coded, and maintained by a single independent developer in Denmark — no team, no investors, no roadmap handed down from anyone else. Every part of it, from the harmonic tuning engine and the DSP to the plugin builds and the website you are reading now, is the work of one person who wanted a tool that treats musical notes as relationships instead of fixed grid positions.
The design, the C++ audio engine, the synthesis, the plugin and standalone builds, the documentation, and this site are all handled by a single developer. When you post in the Discord or send a support email, you are talking directly to the person who writes the code.
No existing DAW or piano roll let you compose with pure harmonic ratios the way the ear actually hears them. Arbit began as the tool its author wanted and could not find, and grew into a full harmonic workstation.
There is no venture funding and no pressure to chase trends. Features land when they are right, the free tier stays genuinely free, and the project answers to the people who use it.
Arbit is developed in Denmark and used by composers, sound designers, and xenharmonic experimentalists around the world. It is in active open beta, with new releases landing regularly.
Arbit Free is a full harmonic DAW. Download it, or come say hello in the Discord.
