  > "ACE-Step 1.0 + YuE2 = Win. Since Ace Step 1.0 has superior creativity but terrible sound quality , you can now save your older Tracks or just hunt for new ones. Because with SheetSage2+YuE2 you can just extract the ABC and make a high quality remix with YuE2. ACE-Step 1.0 needs really many seeds to produce a unique melody, but if it hits - it hits. There is nothing out there that can match it."

  > "Ace-Step 1.5 XL - I am late to the party but...wow!. I have been experimenting with ACE-Step 1.5 XL and while there needs to be some cherry-picking and some proper prompting and Lyrics, you really can get some really good outputs. The really cool thing is that it can do quite a few music styles, this one is quite chill, perhaps I'll post other stuff too, if you guys like it (I only have made songs in other styles for now, though)"

  > "Ace-step 1.5 XL reference and LoRa. I've been playing around attempting how powerful Acestep 1.5 XL Turbo actually is. And I feel reference mode doesn't style the song as per the reference as strong as a LoRa would do. Did you guys get any good results referencing other tracks? Does repainting or cover mode work better than referencing (I'm also getting kind of bad results)? I'm using the starsFriday ComfyUI nodes ( https://github.com/starsFriday/ComfyUI-ACEStep )."

  > "Ace Step 1.5 + LTX-2.3 (8GB VRAM). I asked Copilot to help me with some tags for the song "Carmina Burana". Then used Ace-Step 1.5XL Turbo to generate the audio clip with Chinese lyrics. I used Nano Banana (free credit) to generate the end frame. Then modified it with Qwen 2511 to lower the women's head for the 2nd key frame and changed the angle for the 1st frame. Finally, I ran LTX-2.3 (distilled 1.1) with audio injection. 768x576 is the highest resolution I could get (with my RTX-4070 8GB) without out of memory, generation time 416s. Any tips to get higher resolution, e.g. 640p?"

  > "How to turn ACE-Step 1.5 into a Suno 4.5 killer. I have been noticing a lot of buzz around ACE-Step 1.5 and wanted to help clear up some of the misconceptions about it. Let me tell you from personal experience: ACE-Step 1.5 is a Suno 4.5 killer and it will only get better from here on out. You just need to understand and learn how to use it to its fullest potential."

  > "ACE-Step-1.5 has just been released. It’s an MIT-licensed open source audio generative model with performance close to commercial platforms like Suno. https://xcancel.com/acemusicAI/status/2018731205546684678 https://ace-step.github.io/ace-step-v1.5.github.io/ It’s already supported in Comfy. MIT license. HuggingFace Demo is also available! Pretty much the whole package - LoRAs are supported, multiple different models to tailor to different needs, cover and repainting features. This is the closest open-source has gotten to Suno and similar top-slop platforms."

  > "1 Day Left Until ACE-Step 1.5, Open-Source Music Gen That Runs on <4GB VRAM Open suno alternative (and yes, i made this frontend). An open-source model with quality approaching Suno v4.5/v5... running locally on a potato GPU. No subscriptions. No API limits. Just you and your creativity. We're so lucky to be in this era of open-source AI. A year ago this was unthinkable. Frontend link: Ace Step UI is here. You can give me a star on GitHub if you like it. https://github.com/fspecii/ace-step-ui Full Demo https://www.youtube.com/watch?v=8zg0Xi36qGc ACE-Step UI now available on Pinokio - 1-Click Install! https://beta.pinokio.co/apps/github-com-cocktailpeanut-ace-step-ui-pinokio Model live on HF"
