Clarification requested: rights and terms for music generated by ACE-Step 1.5

[moygeniral-cloud]

Hello ACE-Step team,

I'm evaluating ACE-Step 1.5 as an optional, offline audio source for an open-source audiovisual production pipeline.

Before running any model or publishing generated audio, I'd appreciate written clarification of the intended terms for generated music.

The reviewed model cards state that generated music can be used for commercial purposes. Could you please clarify whether this means that users may:

1. Generate and store audio privately.
2. Modify, edit, remix, or combine generated audio with video and other media.
3. Publish and distribute generated audio publicly.
4. Monetize it through music distribution, YouTube, TikTok, advertising, client work, or similar commercial channels.
5. Redistribute the resulting audio files without distributing the model weights.
6. Do so without additional attribution to ACE-Step or AI disclosure, unless another rule requires it.

Could you also clarify:

7. Does the ACE-Step project claim any ownership or continuing rights in generated audio?
8. Are there any output-specific restrictions beyond lawful use and respecting third-party copyright, trademarks, voice, likeness, and input-material rights?
9. Do these answers apply specifically to the following immutable model revisions?

• ACE-Step/Ace-Step1.5

• ACE-Step/acestep-v15-base

• ACE-Step/acestep-v15-sft

• ACE-Step/acestep-v15-xl-base

• ACE-Step/acestep-v15-xl-sft
d06de46b4622f781cf07f4a013a67d591ca52819

If possible, could this clarification also be added to a versioned LICENSE, OUTPUT_TERMS, or model-card section so downstream users can cite a stable official source?

I understand that ACE-Step cannot warrant that every generated result is non-infringing, and that users remain responsible for prompts, reference audio, protected styles, voices, likenesses, and other third-party material.

Thank you for clarifying.
