2026 update: Add Instrumental API is available on PoYo at 20 credits per generation, about $0.10. This AI music generation tool transforms your vocal recordings into full musical tracks by generating professional-quality instrumental accompaniment.
What is Add Instrumental API?
Add Instrumental API takes an audio file containing vocals or melodies and generates matching instrumental backing tracks. Using advanced AI, it analyzes your audio and creates accompaniment that complements your vocals in the style you specify.
Whether you're a musician looking to quickly prototype ideas, a content creator needing background music, or a producer exploring new arrangements, Add Instrumental API provides a fast and flexible solution.
Key Features
Vocal to Full Track Conversion
Upload your vocal recording and receive a complete instrumental arrangement. The AI analyzes your melody, rhythm, and style to create accompaniment that fits naturally.
Style Tag Control
Guide the generation with descriptive tags like "acoustic, pop, passionate" or "hip-hop melodico". Use negative tags to exclude unwanted styles like "trap, rap" or "dance pop".
Multiple Model Versions
Choose between model versions:
- V4_5PLUS - Balanced quality and speed
- V5 - Latest model with enhanced capabilities
- V5_5 - Personalized model tuned for more tailored musical taste
Vocal Gender Selection
Specify the vocal gender ("m", "f", or "none") to help the AI better understand and complement your audio.
Style Weight Control
Fine-tune how strongly the style tags influence the output with adjustable style weight parameters.
