-- Output from midi2lua { ticks_per_beat = 480, tracks = { { -- Track 1: Piano { tick = 0, type = "note_on", note = 60, velocity = 100 }, { tick = 120, type = "note_off", note = 60, velocity = 64 }, { tick = 240, type = "note_on", note = 64, velocity = 95 } } } } 1. Rhythm Games (Roblox / Love2D) If you are building a Dance Dance Revolution or Guitar Hero clone in Roblox (Luau) or Love2D, timing is everything. midi2lua allows your level designers to compose in FL Studio or Ableton, then drop the exported file into your game’s asset pipeline.
I use midi2lua to control DMX lights. I draw the "chase" pattern in a MIDI clip (C4 = Red, D4 = Blue), convert it to Lua, and let the script run the light show. No expensive lighting software required. A Simple Example (Love2D) Assume you have a file called song.lua that was generated by midi2lua .
If you’ve ever built a rhythm game, programmed a generative visualizer, or tried to sync a light show to a backing track, you know the pain of manually transcribing note data. You have a beautiful melody in your DAW (Digital Audio Workstation), but your Lua script just sees a list of numbers. midi2lua
Enter —a lightweight utility that acts as a translator between the universal language of MIDI and the elegant simplicity of Lua tables. What is midi2lua ? At its core, midi2lua is a parser/converter. It takes a standard .mid file (or raw MIDI bytes) and converts the event stream into a native Lua data structure.
Turning MIDI notes into executable code for games, visuals, and custom DAW tools. -- Output from midi2lua { ticks_per_beat = 480,
-- main.lua local midi_data = require("song") -- A simple scheduler local current_tick = 0 local bpm = 120 local ticks_per_beat = midi_data.ticks_per_beat
Instead of hardcoding noteOn(60, 100) a thousand times, you feed your MIDI file into midi2lua , and it outputs a table like this: I use midi2lua to control DMX lights
