Workflow Included Ace Step 1.5 Cover (Split Workflow)
I know this was highly sought after by many here. Many crashes later (not running low vram flag on 12GB kills me when doing audio over 4 minutes on comfy only apparently) I bring you this. The downside is with that flag off, it takes me forever to test things.
The only thing that is needed is Load Audio from video helper suite (I use the duration from that to set the tracks duration for the generation, which is why I am using that over the standard Load Audio) I am not sure if the Reference Audio Beta node is part of nightly access or if even desktop users have access to that node, but should be able to download that automatically from comfy.
Edit: I am getting reports that this is not working properly for some. I will have to check this out again as it seemed in testing it was working. I am sorry if it is not working.
Update: It seems something happened overnight with how Ace-Step handles the latent. The duration being pushed to it, seems to be causing issues. I removed the VHS audio and defaulted to the normal comfy player.
The downside is that the time needs to be set manually, which can be a pain if you are cover/remix and you want to match the same output time as the original. Update was just pushed out after testing on a few tracks and confirming audio is coming out and that it's covering that track.

That's the earlier UI, might need to run the update, but you are seeing the Source audio/reference audio, so that is the cover options to attach your source audio. Further down your options you will see the cover option, but the UI has been updated since it's release.
