Muse is an innovative software designed for MIDI composition and editing that leverages artificial intelligence to assist users in crafting musical ideas, generating elements like chords, melodies, basslines, and drums based on simple language prompts or pre-existing content, while allowing for interactive refinement through intelligent feedback. By incorporating principles of music theory such as harmonic function and voice leading, it encourages users to delve into creative avenues they may not have otherwise considered. Additionally, creators can upload, modify, or remix MIDI tracks and collaborate with the AI in real-time, facilitating a swift iterative process. The platform is compatible with various AI models, including GPT-5.2, Gemini, and specially designed agents for musical reasoning, and it features capabilities like chat-based feedback on compositions, real-time MIDI adjustments, multi-track creation, advanced arrangement tools, and the option to export music as standard MIDI or audio files for integration into digital audio workstations. Furthermore, Muse's user-friendly interface and versatile tools empower both novice and experienced musicians to enhance their creative workflow.
