Protoplug ~ Scriptable Audio Plugins


Create audio plugins on-the-fly with LuaJIT.

Protoplug is a VST/AU plugin that lets you load and edit Lua scripts as audio effects and instruments. The scripts can process audio and MIDI, display their own interface, and use external libraries. Transform any music software into a live coding environment!

Cross-platform: builds for Windows, Mac OS X and Linux. This means that all protoplug scripts are compatible with these platforms and can be loaded into a huge amount of audio software (glory to JUCE).

Fast: Use the speed of LuaJIT, and perform DSP tasks as efficiently as old school C implementations.

Free and open source: Want a new feature? Add it yourself. The source is MIT-licensed and available on Github.

You can use this program to play your collection of CDG, MIDI and MPEG karaoke songs. No songs are provided, you must obtain these from elsewhere.

Visit here to find out more about what a CDG or MP3+G file is. In short, CDG is the format of professional karaoke CDs. These CDs can be ripped to your hard disk, and turned into a .mp3 file together with a .cdg file. This player gives you the ability to play those mp3+cdg files.

PyKaraoke Features:

  • CDG (MP3+G, OGG+G, WAV+G) playback – Play standard CDG karaoke files
  • MIDI (.MID/.KAR) playback – Play MIDI format karaoke files
  • MPEG playback – Play karaoke songs and movies in MPEG format
  • Other formats – Play any other video formats by launching an external media player
  • Playlist – Queue up songs, sit back and enjoy
  • Searchable song database – Easily find your songs from the main screen
  • Search inside ZIP files – Play MP3+G/MIDI files wrapped in ZIP files
  • Cross-platform – Runs on Windows, Linux, BSD, OSX and GP2X
