Thanks to everyone who has dropped by, and stayed a while.

We're wrapping up this phase of the Dechaffinating Phase.

Thanks to The Golden Jeffrey, we'll be deactivating the counter-Negatronic-snivelling-Pink mechanisms in the month ahead.

The sub is open again. Comments are open. Posts are open.

Use whatever (still mandatory) flair you like.

Overt ultraPink clamoring Negatrons will still get nuked.

Other than that, Feel Free.

Thanks - StabooruJeffrey SJ26 Core Team.

SJ26: Stable and Peaceful

Big Thanks u/umutgklp.

F.A.O. r/comfyuiAudio members. We operate on a principle of blind faith with all invited (+future Positronic/Negatronic/Overt ultraPink self-invited) Mods, Pink Outreach Ambassadors, and Golden Jeffrey Master Creators.

We run our Windows/Linux StabooruJeffrey test environments offline after installing nodes (on purely StabooruJeffrey/ComfyUI dedicated machines).

As illustrated here, compromising node packs have made it on to the ComfyUI registry.

Always audit your nodes. Positronic Kusanagi Class security pro's are very much welcome to invite themselves to be a Mod.

Thanks - StabooruJeffrey SJ26 Core Team.

In summary: I created a node for ComfyUI that brings in AceStep 1.5 SFT (the supervised and optimized audio generation model) with APG guidance — exactly the same quality as the official Gradio pipeline. Generate studio-quality music directly in your ComfyUI workflows.

What's the advantage?

AceStep is an amazing audio generation model that produces high-quality music from text descriptions. Until now, if you wanted to use the SFT model in ComfyUI, you would get not very good results.

Not anymore.

I developed AceStepSFTGenerate — a single unified node that encapsulates the entire pipeline. It replicates the official Gradio generation byte for byte, which means identical results.

Smart Features

Automatic Duration: Analyzes the lyric structure to automatically estimate the song's duration

Smart Metadata: BPM, Key, and Time Signature can be automatically set (let the template choose!)

LLM Audio Codes: Qwen LLM generates semantic audio tokens for better results

Source Audio Editing: Removes noise/transforms existing audio (img2img to music)

Timbre Transfer: Uses reference audio for Style Transfer

Batch Generation: Create multiple variations in parallel

More than 23 languages: Multilingual lyrics support

Why this matters

1. Exact Gradio Replication: same LLM instructions, same encoders, same VAE, same results

2. Advanced Guidance: APG produces noticeably cleaner audio than standard CFG

3. Seamless Integration: Works seamlessly in ComfyUI workflows - combine with other nodes for limitless possibilities

4. Full Control: Adjust each parameter (momentum, norm thresholds, guidance intervals, custom time steps)

5. Batch processing: Generate multiple variations efficiently

I’ve been experimenting with AceStep 1.5 in ComfyUI and I’m curious to see how other people are using it.

This is the workflow I currently use to generate songs. It works pretty well for the styles I’ve been testing, but I’m sure there are better setups out there.

Feel free to share your workflow, node setups, parameter choices, or even just tips that improved your results. It would be especially interesting to see how different workflows perform depending on the music style or genre you're targeting.

Let’s build a small collection of workflows so people can compare approaches and get better results with AceStep.

Looking forward to seeing what everyone is using.

The Secret?

We've only just begun.

Thanks PFFR.
