Generate music from text prompt using Ace Step model.
  • Output Type: audio
  • Base Model: musicgen
  • Estimated Cost: 0.2 * duration * (number_of_steps/60) credits
  • Handler: replicate

​
Parameters

​
Required Parameters

​
tags
string
required
Text prompts to guide music generation (e.g., genre, mood, instruments, BPM). Supports tags, descriptions, and scenes. Use commas to separate different tags. E.g., ‘synth-pop, electronic, pop, synthesizer, drums, bass, piano, 128 BPM, energetic, uplifting, modern’
  • Label: Tags (Prompt)

​
Optional Parameters

​
lyrics
string
default:"[inst]"
Optional lyrics for the music. Can be multi-line. Use [verse], [chorus], and [bridge] to separate different parts of the lyrics. Use [instrumental] or [inst] to generate instrumental music.
  • Label: Lyrics
​
duration
integer
default:30
Desired duration of the generated audio in seconds.
  • Label: Duration
  • Minimum: 1
  • Maximum: 240
​
seed
integer
default:"random"
Seed for the generation. Set for reproducibility. If blank, a random value will be used.
  • Label: Seed
  • Minimum: 0
  • Maximum: 2147483647
​
number_of_steps
integer
default:60
Number of inference steps. (More can improve quality but will increase cost/latency.)
  • Label: Number Of Steps
  • Minimum: 10
  • Maximum: 200
​
granularity_scale
float
default:10
Omega scale for APG guidance (granularity scale), or similar for other CFG types. Higher values can reduce artifacts.
  • Label: Granularity Scale
  • Minimum: -100.0
  • Maximum: 100.0
​
guidance_interval
float
default:0.5
Guidance interval.
  • Label: Guidance Interval
  • Minimum: 0.0
  • Maximum: 1.0
​
guidance_interval_decay
float
default:0
Guidance interval decay.
  • Label: Guidance Interval Decay
  • Minimum: 0.0
  • Maximum: 1.0
​
guidance_scale
float
default:15
Overall guidance scale. Controls how much the generation adheres to the prompt. Note that when lyric_guidance_scale > 1 and tag_guidance_scale > 1, this global guidance scale might not be applied.
  • Label: Guidance Scale
  • Minimum: 0.0
  • Maximum: 30.0
​
min_guidance_scale
float
default:3
Minimum guidance scale.
  • Label: Min Guidance Scale
  • Minimum: 0.0
  • Maximum: 100.0
​
tag_guidance_scale
float
default:0
Guidance scale for tags (text prompt). This is the specific guidance scale for the text component and typically applies to CFG. A suggested starting point could be around 5.0 (especially if lyric guidance is around 1.5).
  • Label: Tag Guidance Scale
  • Minimum: 0.0
  • Maximum: 10.0
​
lyric_guidance_scale
float
default:0
Specific guidance scale for the lyric component.
  • Label: Lyric Guidance Scale
  • Minimum: 0.0
  • Maximum: 10.0
