I used Gemini Vibe Coding to create an AI composition application. The idea is to use AI to generate sheet music and then convert it into music. Currently, it can only be converted to MIDI, but in the future, if integrated with a better mixing service, the results would be even better.

This is mainly to test AI's understanding of the mapping from sheet music to music. My testing shows it works pretty well, but my musical skills are limited. If any fellow music enthusiasts want to try it out and give feedback, that would be great.

Here is the demo video:
