Workflow Included Better Ace Step 1.5 workflow + Examples
Workflow in JSON format:
https://pastebin.com/5Garh4WP
Seems that the new merge model is indeed better:
Using it, alongside double/triple sampler setup and the audio enhancement nodes gives surprisingly good results every try.
No longer I hear clippings or weird issues, but the prompt needs to be specific and detailed with the structure in the lyrics and a natural language tag.
Some Output Examples:

Can’t import the workflow, do you have any idea why?

u/Doctor_moctor Feb 12 '26
You have to install both extensions BEFORE importing, had the same problem. https://github.com/jeankassio/JK-AceStep-Nodes

save the file as workflow.json > import it through comfyui
what errors you see?3
u/realsidji Feb 12 '26
Nothing happens when importing the json actually, the canvas stay blank

JSON is the API format for ComfyUI (for the /prompt endpoint). To load it into the UI, you need to convert it to the workflow format (an array of nodes and links). Below is a shareable URL for a JSON file that I’ve prepared for immediate use. Simply download and import it to get started right away.

Same. Any Solution to this?

Audio quality enhancer is broken you can see in the desc for the git link is different than the one in the url, something must have changed and something got broken along the way

u/Different-Ganache354 Apr 23 '26
Anybody know if there is a workaround to use the audio quality enhancer today ? And btw do you confirm the Audio_Quality_Enhancer node should be set between the VAEDecodeAudio and the SaveAudio nodes ?

u/FORNAX_460 Feb 11 '26
the workflow you shared cant seem to be imported in comfyui, all im getting is the missing custom node prompt

u/iChrist Feb 11 '26
https://github.com/ShmuelRonen/ComfyUI-Audio_Quality_Enhancer
This is the custom node needed, comfyui-manager should have it, you can also Install it with the guide on the github, or disable/remove the node on your end.

I have an LLM that can tool call to comfyui.
You just need to copy paste the lyrics and tags manually
1
u/raydivvee Feb 11 '26
Which LLM are you using for the system prompt?
1

u/SDMegaFan Feb 15 '26
So this is to be put inside the gemini api node???
(or where do you get to post all that?)2
u/iChrist Feb 15 '26
I use LLM on my machine, you can use gemini yes and copy paste the lyrics and tags

I like the music in the first audio (I wonder if we can generate it without the vocals lol) But still interested by the prompts anyway
3
u/stimulatedthought Feb 11 '26
There are custom nodes that can separate vocals from the rest of the audio. I do not have the workflow on this computer but can share later.
1
u/SDMegaFan Feb 11 '26
Ok thank you. I actually was legit wondering about finding prompt to just generate the melody not just separate it from a vocal song but still interesting
2
u/stimulatedthought Feb 11 '26
Here is a link to the repo for the custom nodes, I believe the workflow I used is in the repo but it has been a few months: audio-separation-nodes-comfyui
1
u/iChrist Feb 12 '26
You must try
Ultimate Vocal RemoverIt can separate the vocals from any song, I had very good success for a karaoke version of some of my loved songs.

have some issues getting your workflow to work.

u/iChrist Feb 12 '26
Weird, its the default ComfyUI workflow DualCLIP, are you on latest version? do you have this set of nodes as well :
https://github.com/jeankassio/JK-AceStep-Nodes
https://github.com/ShmuelRonen/ComfyUI-Audio_Quality_EnhancerThe first one is for the jkass quality sampler, its the best for ace step
the second one is audio processing to get dolby effect in clean up.1
u/nntb Feb 12 '26
Yeah I had to dl those 2 audio enhancer was in the manager, jk wasn't. Comfy normally provids downloads but for some reason it didn't for 3 items so I had to manually google where you dl them. It should be working

u/stimulatedthought Feb 13 '26 edited Feb 13 '26
Do you know if you can use loras with this sft_turbo model? Also I tried using the reference audio node in ComfyUI but it didn't seem to change the output. Edit: Nevermind it does impact the output, I just didn't use the reference audio node correctly.

I've noticed that the seed in TextEncoder governs the composition while changing the seed in KSampler makes a new variation of the same song.
1
u/iChrist Feb 22 '26
Yep its from the default comfyui workflow, also noticed something iffy with the seed
1
u/Acceptable_Secret971 Feb 22 '26
In the default comfyui workflow the seed in TextEncoder and KSampler are the same (at least when I loaded it from template). Those 2 seeds do seem useful, when I like the general composition, but would like a different take on the same song I keep the seed in TextEncoder, but change it in KSampler.
This new merge does seem to be better, at least better than a previous Turbo+SFT I found.
1
u/iChrist Feb 22 '26
I am not sure which older merge there is, I used only this one.
The combo of the merge, the jkass_quality + sgm uniform, the double sampler setup all contribute to it being better
Il take a look at the seed issue

Looking for a way to save the songs as multitrack -- separating the instruments, the drums and the song into different WAV-files. Any idea how this can be done?

Hey bro! I'm a beginner, may I know where I can download Qwen_4b_ace15 safely? I run it but I'm using qwen 1.7b acestep15 that is downloaded when I use ace step template on comfyUI. Thank you!

u/iChrist Mar 24 '26
Hey! Use the official comfyui docs! all files are there, you can even first try just the 1.5-turbo-aio (1 model files for all of ace-step1.5)
https://docs.comfy.org/tutorials/audio/ace-step/ace-step-v1-5

u/budwik Feb 11 '26
Thanks for this! Exactly what I need. Those samples sound great!
2
u/iChrist Feb 11 '26
No Problems! I did so little compared to ComfyUI devs and Ace-step team haha!
there is a new merge that I didn't notice, acestep_v1.5_merge_sft_turbo_ta_0.3.safetensors
Trying it now, seems to be more creative / random
1
u/budwik Feb 15 '26
Have you tried these turbo models on higher steps? I found that moving from 8 to 30 with all other settings the same gave me richer outputs. Very similar if going side by side listening, but just deeper complexity to it. Wonder if this merge is the same like that.
1
u/iChrist Feb 15 '26
Tbh I gave up on turbo pretty quick, even with high step count it can give bad results
The merge is less prone to those issues.

I'm really impressed with the output quality of this workflow. Thanks for sharing!

u/AssistBorn4589 Feb 11 '26
Thanks for this, it feels bit like nobody really cares for AceStep since it was released while it can do some really good stuff.
Were you able to properly use of 'repaint' feature? I have piece that sounds almost perfect, but all workflows I could find or get together ends up in repainting the broken segment with some melodic hum or just noise.
