[Feature Request]: ComfyUI - ACE Step 1.5 workflow Reference Voice

### Description

Hi, this is about ComfyUI - ACE Step 1.5.
Is there a workflow with Reference Voice Clone?
I would like to have vocals with a specific voice.
I think something like LoadAudio would be needed, but how would
you connect it and so on?
I would like to have a workflow if that's possible.
Greetings from Germany...

### Additional information
Or is it possible to create two audio files, one with vocals and the same one without vocals, so that you also have the instrumental version of the song and can sing along to it later, placing both tracks on top of each other so that you can sing along to the vocals?
