Simple Karaoke or getting the best from your Midi Synthesizer!

KMid is part of Extragear, so it does not necessarily ship on the same date as KDE SC. The latest stable release is 2.4.0, published on August 15th, 2010.

So what is the current status?

Currently implemented

Here are some major features implemented in KMid:

  • MIDI and Karaoke files are supported.
  • Playback to external hardware MIDI devices.
  • Allow to use software synths as well, like Timidity++ and QSynth/FluidSynth.
  • Tempo and volume controls.
  • Added a pitch (transpose) control.
  • Rhythm view (visual metronome).
  • Configurable character encoding, font and color for lyrics.
  • Playlists (song collections).
  • MIDI Mapper, translating General Midi events into other events understood by some synthesizers.
  • Channel window, with solo/muting controls and instrument selectors.
  • Piano player window, using VMPK artwork and technology.
  • Konqueror integration.
  • Runs in Linux, Windows and Mac OSX.

Notes for usage

  • If you use Timidity++ as a software synthesizer, you may have to install GUS patches or sound fonts. You can find them at freepats
  • Fluidsynth is an alternative. It has a helpful gui called QSynth. For soundfonts, try General User GS.
  • For more information and options, there is a tutorial available.


  • Source packages
  • openSUSE Build Service - Search packages
  • Mandriva and Fedora users: available at the official repositories of your Linux distribution.
