🎼 Real-Time MIDI Notation

Real‑time multi‑track MIDI visualization & notation engine (Python, Pygame)

A high‑performance renderer for real‑time MIDI events with 16‑track support, advanced beams, velocity dynamics, and a fully modular UI.

🔍 What is Real-Time MIDI Notation?

Real-Time MIDI Notation is a real‑time multi‑track MIDI renderer written in Python.
It converts incoming MIDI events into live notation, including:

• real‑time note placement
• multi‑track color coding
• velocity‑based dynamics
• beams, stems, barlines
• grid, timeline, and playhead
• full Yamaha 16‑track standard
• real‑time activity meters
• zoom + scroll

This project aims to evolve into a full real‑time engraving engine, similar to MuseScore or LilyPond, but optimized for live MIDI input.

🎯 Who Is This For?

• MIDI visualizers
• DAW companion tools
• real‑time notation engines
• music education software
• live performance analysis
• Yamaha arranger keyboard users
• MIDI debugging and development

🧩 Why This Project Matters

Real‑time notation is a non‑trivial engineering challenge.
Most notation engines (MuseScore, LilyPond, Dorico) are offline engravers — they expect complete musical context.

This project solves:

• real‑time note grouping
• real‑time beam detection
• real‑time velocity dynamics
• real‑time multi‑track rendering
• real‑time layout engine (no pre‑analysis)

This makes it ideal for:

• research
• education
• live performance tools
• MIDI hardware development

---

🎓 Academic Relevance

This engine is suitable for:

• music informatics research
• real‑time systems courses
• MIDI protocol analysis
• digital signal processing labs
• human–computer interaction studies
• music pedagogy and visualization

A full CITATION.cff file will be added for academic referencing.
