Question 1

What is YuE2 and how does it generate full songs?

Accepted Answer

YuE2 is an open-weights foundation music model developed by Multimodal Art Projection (M·A·P) and academic collaborators. It unifies symbolic planning (ABC notation and chord progressions) and neural audio diffusion, generating complete songs with full vocals and accompaniment in 48kHz high-fidelity stereo.

Question 2

How does Symbolic Planning differ from black-box AI music models?

Accepted Answer

Traditional AI music generators act as black boxes where users cannot intervene in chord structures, tempo, or melodies. YuE2 first produces an explicit, transparent ABC 2.1 musical score as an intermediate Chain-of-Thought (CoT) representation, allowing human musicians and AI agents to reharmonize, transpose, and adjust arrangements before audio rendering.

Question 3

How does YuE2 approach a song?

Accepted Answer

YuE2 writes an editable ABC score first, then renders audio. Exports are the ABC score, MIDI note tracks parsed from that score (master, vocal, instrument, and chords), a MusicXML lead sheet, and a 48kHz stereo FLAC mix. There is no separated audio-stem download.

Question 4

How do Audio-to-Score Transcription and MERT2 work in the YuE2 ecosystem?

Accepted Answer

YuE2 integrates an audio-to-score neural transcription pipeline capable of transcribing raw audio into structured ABC sheets and multi-track MIDI. MERT2 (and MERT2-FS) is a self-supervised music representation foundation model that excels across the MARBLE benchmark for music understanding and retrieval.

Question 5

Can I edit the chords and melody with natural language?

Accepted Answer

Yes! The built-in YuE2 Music Agent understands music theory and conversational instructions, such as reharmonizing pop chords into jazz ii-V-I progressions, transposing keys, shifting octaves, or verifying measure alignments.

Question 6

What are the licensing terms for YuE2 weights and output audio?

Accepted Answer

YuE2-3B model weights are released by M·A·P under the CC BY-NC 4.0 license, while inference code is Apache 2.0. Individual creators retain rights to use their generated musical pieces in creative projects. Note that AI-generated audio cannot guarantee complete exemption from third-party copyright or Content ID similarity matches; users are advised to review before major commercial distribution.

Question 7

What is the relationship between yue2music.com and the M·A·P team?

Accepted Answer

YuE2 Music Studio (yue2music.com) is an independent, community-driven cloud creation platform built upon the open-source YuE2 foundation model. We provide a hosted Web UI, symbolic editing tools, and GPU inference runners to help musicians create music without setting up local GPU environments. We are not the official academic institution, and we actively maintain and display full academic citations to the original authors.

Question 8

新規ユーザーに無料クレジットはありますか？20クレジットはどう受け取れますか？

Accepted Answer

はい。アカウントを登録するだけで、すぐに20クレジットが無料で付与されます（クレジットカードの登録は不要です）。48kHzのフル楽曲は1曲10クレジットなので、無料分で2曲まで作れます。無料クレジットの有効期限は付与から7日間です。ABC楽譜の編集やAI伴奏も、お金をかけずにお試しいただけます。

Question 9

料金はどんな仕組みですか？サブスクなしでクレジットを買えますか？

Accepted Answer

買い切りのクレジットパックと、いつでも解約できる月額・年額プランの両方があります。クレジットを買うためにサブスクは必須ではありません。48kHzのフル楽曲は1曲10クレジット、エージェントによる楽譜の修正は1回2クレジットです。買い切りパックの有効期限は、Creator Passが30日、Pro Musicianが90日、Studio Masterが180日です。

Question 10

生成に失敗した場合も料金はかかりますか？自動で返金されますか？

Accepted Answer

失敗した生成にクレジットはかかりません。GPUのメモリ不足や通信の切断、タイムアウトなどで48kHzの音声が届かなかった場合、差し引かれた10クレジットは自動ですぐに残高へ戻ります。クレジットの動きはすべて利用履歴で確認できます。

Question 11

How long does it take to generate a complete song?

Accepted Answer

The symbolic planning phase (ABC score, chord progression, and lyrics) generates within 2–5 seconds and can be instantly previewed via the browser synthesizer. Final 48kHz master rendering on RunPod GPU workers typically takes 30 to 60 seconds for a standard arrangement (approx. 1 to 2 minutes of music).
