复办钢琴表现力渲染竞赛，9支国际团队展示音乐表达新进展。
RenCon 2025: Revival of the Expressive Performance Rendering Competition
- 分两阶段评估：线上初评+会议现场实时演奏
- 9个参赛系统展现显著表现力提升，但未达人类水平
- 适合音乐人工智能、人机交互研究者参考
本文全面记录了2025年在韩国大田举行的ISMIR 2025会议上复办的表达性钢琴演奏渲染竞赛（RenCon 2025）。竞赛吸引了来自国际研究团队的9个参赛作品，涵盖多样化的表达性钢琴演奏生成方法。评估采用两阶段结构：前期在线评审与会议现场实时渲染。我们分析了竞赛形式、参与者背景、系统表现及未来改进经验。结果表明，当前技术在表达性渲染方面取得显著进步，但仍面临实现人类级音乐表现的挑战。
原文摘要 · Abstract (English)
This paper presents a comprehensive documentation of RenCon 2025, the revival of the expressive performance rendering competition which took place at ISMIR 2025 in Daejeon, Korea. The competition attracted 9 entries from international research groups, representing diverse approaches to expressive piano performance rendering. The two-phase assessment structure comprised a preliminary online evaluation and live real-time rendering at the conference. We analyze the competition format, participant demographics, system performance, and lessons learned for future iterations. The results demonstrate significant advances in expressive rendering capabilities while highlighting remaining challenges in achieving human-level musical expression.
