MIDI is the lingua franca of electronic music. It’s a protocol that has been around since the 1980s, and it is incredibly efficient. However, a standard .mid file is a binary blob. You can’t open it in a text editor and make sense of it. To edit a MIDI file, you need a piano roll interface.

Whether you are a modder for a popular rhythm game, a developer building an interactive music system in , LÖVE (Love2D) , or Defold , or an artist trying to trigger lighting cues via a MIDI controller, midi2lua is the unsung hero of the workflow. midi2lua

A standard MIDI file stores data chronologically as a series of events. A midi2lua converter parses this binary data and translates it into a structured Lua table (an array or dictionary). 1. The Raw MIDI Data In a MIDI file, a note event looks something like this: MIDI is the lingua franca of electronic music

Ensure your converter supports tempo maps, otherwise, the song will play back at a constant, incorrect speed. Conclusion You can’t open it in a text editor and make sense of it

1. Read MIDI file (binary) 2. Parse header chunk (format, tracks, ticks per quarter note) 3. For each track: - Run through MIDI events (running status, meta events, sysex) - Collect note_on/off, tempo, time signature, etc. 4. Convert absolute ticks to: - Relative ticks (difference from previous event), or - Milliseconds (if tempo events are processed) 5. Emit Lua table syntax to stdout / file

Assuming you have the tool installed (or the script cloned), usage is typically as simple as a command line argument:
