What is MIDI-GPT?
MIDI-GPT is an AI tool that generates musical compositions, melodies, and sounds using machine learning. Built on Replit, it allows users to create MIDI files by describing what they want musically or by providing parameters. The tool is useful for musicians, producers, and composers who want to explore new ideas quickly or overcome writer's block. Rather than composing from scratch, you can use AI to suggest variations or complete arrangements. It works best as a creative starting point; most users refine the output rather than use it unchanged.
