What is vibetune?

Vibetune is a command-line tool that generates MIDI background music based on a text description of a mood or style. You type a phrase like "lofi study beat, rainy afternoon, jazzy chords" into a terminal prompt, and it produces a music track you can listen to right there and then export for use in short videos or other projects. The tool works by sending your vibe description to a locally running language model through a separate program called Ollama. The language model interprets the description and outputs a structured music specification: key, tempo, chord progression, and instrument choices. Vibetune then turns that specification into actual MIDI audio using a sound synthesis library called FluidSynth. Everything runs on your own machine with no internet connection required for the generation itself. Once a track is generated you can play, pause, and stop it without leaving the terminal. You can trim it to a specific length, crossfade the ending back into the beginning for a seamless loop, check info about the key and chords used, save it with a name of your choosing, or discard it if you want to try again. There is also a variation command that generates a new track in the same style with different musical choices, and a preset system that lets you save favorite vibe descriptions and reuse them later. Setup requires installing Ollama and pulling a specific language model, installing FluidSynth, and then installing vibetune itself via pip. The README lists commands for macOS and Linux. The default model is a small 4-billion-parameter version, but you can switch to a larger or different one from inside the tool. The project is at an early stage with no stars. The README is focused on usage and setup, with no contribution guide or license information mentioned.
