ACE-Step 1.5 XL Turbo: local setup and music tests

This tutorial installs ACE-Step 1.5 XL Turbo on an Ubuntu server with an Nvidia RTX 6000 and 48 GB of VRAM. The presenter clones the repository, installs prerequisites including vLLM, and starts the supplied Gradio demo. The first launch downloads model files; the browser interface runs on localhost port 7860.

The local AI tests begin with an Urdu Sufi Qawwali prompt. The presenter prefers the first result and describes the second as closer to a Bollywood song, with some mistakes. A Spanish test combines supplied lyrics with a recording of his speaking voice. He says the result did not capture his tone and timbre, despite finding parts of the singing convincing.

Cover mode receives an instrumental Afrobeat source and a K-pop prompt, then a generated Spanish song. The presenter reports that the instrumental changes style without gaining vocals. He also explains repainting, which lets users regenerate a selected section while keeping the rest of a song, and plays Arabic, Portuguese and German examples.

Performance varies in this session. The presenter reports just over 19 GB of VRAM after loading and no observed rise above 20 GB during the initial generation. He says some runs take 5 to 10 minutes or longer, while later covers finish faster. Claims about beating commercial music tools come from the developers' benchmarks, rather than a controlled comparison in this tutorial.
