Acestep

Generates production music through ACE-Step's open-source models. You can create background tracks for videos, jingles with vocals and lyrics, extract stems, or repaint weak sections of existing audio. The default acemusic cloud provider uses the 4B XL Turbo model with a thinking mode that enriches sparse prompts into detailed musical descriptions. Self-hosting on Modal or RunPod is available but uses the smaller 2B model. Includes scene presets tuned for video production (corporate background, tension, call-to-action) and handles vocal gender through combined prompt and lyric tags. Best for video editors and content creators who need custom soundtrack work without licensing hassles.
