About
Muse is an AI-native MIDI composition and editing tool that empowers users to compose musical ideas with a smart co-writer by generating chords, melodies, basslines, drums, and full arrangements from natural-language descriptions or existing materials, then refining them interactively with context-aware feedback. It understands music theory concepts like harmonic function and voice leading, helping users explore musical ideas they might not discover on their own, and lets creators upload, expand, or remix MIDI tracks, collaborate with an AI agent in real time, and iterate rapidly. It supports multiple AI models, including GPT-5.2, Gemini, and custom agents tuned for musical reasoning, and offers features such as chat-with-your-track feedback, real-time MIDI editing, multi-track generation, extended arrangement tools, and the ability to export compositions as standard MIDI or audio files for use in digital audio workstations.

About
StepAudio 3 is StepFun’s next-generation audio model family, built to understand, generate, and interact through voice, sound, and music. The lineup includes StepAudio 3 Realtime for natural full-duplex conversation, StepAudio 3 ASR for speech recognition, StepAudio 3 TTS for speech synthesis, StepAudio 3 Gen for general-purpose audio generation, and StepAudio 3 Music for long-form music creation. Realtime is designed around a continuous listen-converse-think-act loop, understanding not only words but also hesitation, laughter, emotion, pauses, backchannels, and interruptions. It can think while speaking, reason through harder questions without breaking conversational flow, and use tools to complete tasks once it understands the user’s intent. StepAudio 3 Gen unifies zero-shot TTS, voice design, vocal generation, sound effects, music, and mixed audio generation within one framework, while StepAudio 3 Music supports text-controlled songs, instrumentals, vocal arrangement, and more.
