RenCon 2025: Expressive Performance Rendering Competition
Welcome to the official MIREX wiki page for RenCon 2025, a new task on expressive musical rendering from symbolic scores. This task is part of the MIREX 2025 evaluation campaign and will culminate with a live contest at ISMIR 2025 in Daejeon, Korea. For updates, templates, and examples, please visit our official site: https://ren-con2025.vercel.app
Here is a short summary of the important information:
Task Overview
RenCon challenges participants to develop systems that generate expressive musical audio renderings based on symbolic input (e.g., MIDI, MusicXML). Submissions are evaluated in two phases:
- Phase 1 – Preliminary Round (Online):
Systems submit rendered audio (and optionally symbolic outputs) for both required and free-choice pieces. No real-time constraint is imposed.
- Phase 2 – Live Contest (Onsite at ISMIR):
Top systems will be invited to render a surprise piece using their system in real time at ISMIR. The audience will vote to determine the winner.
Timeline
- May 30 – Aug 20, 2025: Submission period for preliminary round
- Aug 26, 2025: Preliminary round results released
- Sept 10, 2025: Online evaluation results + invitation to live contest
- Sept 2025 (TBD): Live contest at ISMIR 2025
Submission Requirements
Each submission should include:
- Code and checkpoint of your system
- Symbolic inputs and audio outputs for:
- At least 2 out of 3 required pieces
- One free-choice piece (≤1 min 30 sec; max 4 pieces, 5 min total)
- A technical report, including dataset details and post-processing notes
Evaluation
- Online round: Human evaluation and technical inspection
- Live round: Real-time rendering, judged by ISMIR audience
- Objective metrics (e.g., alignment, timing, velocity) are used for analysis but not ranking
Datasets
No restriction on datasets (public, private, internal allowed), but transparency is required.
Post-Processing
Systems must report any post-processing:
- Symbolic-to-audio systems: Describe synthesizers, soundfonts, or piano models used
- Direct audio systems: Note EQ, compression, or other effects
- Interventions: If prompts or editing were used, clarify in your report
- MIDI cleanup: Describe if quantization, editing, or timing correction applied
Minimal human intervention is encouraged unless well-justified.
Organizers
- Huan Zhang (Task Captain, QMUL)
- Junyan Jiang (NYU)
- Simon Dixon (QMUL)
- Gus Xia (MBZUAI)
- Akira Maezawa (Yamaha)
