DARC让鼓点生成同时听音乐上下文和节奏提示，实现精准控制。
DARC: Drum accompaniment generation with fine-grained rhythm control
- 结合其他乐音轨与节奏提示（如拍手、打鼓）生成鼓点
- 在保持音乐上下文感知的前提下，实现细粒度节奏控制
- 适合需要快速试错的音乐制作人和作曲者
在音乐创作中，快速原型设计对探索和优化创意至关重要，但现有生成工具在需要结构控制与风格灵活性时往往力不从心。以往的音轨到音轨生成方法虽可依赖其他乐音轨进行条件生成，但对节奏控制有限；而音色迁移方法虽允许用户指定具体节奏，却无法考虑音乐上下文。我们提出DARC，一种条件生成鼓伴奏的模型，既能基于其他乐音轨提供音乐上下文，又能接受如拍手或打鼓等显式节奏提示。通过参数高效微调，我们在当前最先进的鼓音轨生成器STAGE基础上，引入细粒度节奏控制能力，同时保留对音乐上下文的敏感性。
原文摘要 · Abstract (English)
In music creation, rapid prototyping is essential for exploring and refining ideas, yet existing generative tools often fall short when users require both structural control and stylistic flexibility. Prior approaches in stem-to-stem generation can condition on other musical stems but offer limited control over rhythm, and timbre-transfer methods allow users to specify specific rhythms, but cannot condition on musical context. We introduce DARC, a generative drum accompaniment model that conditions both on musical context from other stems and explicit rhythm prompts such as beatboxing or tapping tracks. Using parameter-efficient fine-tuning, we augment STAGE, a state-of-the-art drum stem generator, with fine-grained rhythm control while maintaining musical context awareness.
