About
GenerativeMIDIs is a project which generates MIDI data fully on-chain. It encodes MIDI raw data in solidity, then generates token URI in a contract. There are so many generative music projects, but there is fewer fully on-chain generative music project. I think this is because of the difficulty encoding the music data in the smart contract. (not like SVG data) This can be used for the template of a new kind of full-on-chain NFT project. We can prove how the music is generated, and who built this logic. This is difficult in the current music industry without smart contract.
How it's made
I researched how MIDI data works from this web page. http://www.music.mcgill.ca/~ich/classes/mumt306/StandardMIDIfileformat.html The code in solidity one by one to make it possible. https://www.npmjs.com/package/midi-writer-js This coding is almost like generating raw binary MIDI data in solidity, so it was tough, but I successfully developed the simple MIDI data. I used a polygon and IPFS for this project.
