ClairObscur - DroneMaker
(& crazy audio effect)
ClairObscur – DroneMaker is a simple device allowing you to create infinite drones from dark textures to bright and elegant tones. It’s a bit special because it’s not an instrument but an audio effect, which means you can drag and drop it on a MIDI or an audio track.
And it works on its own, you don’t need to feed it with sounds (well, you could… and in that case, let the “Global Volume” on 0%! If you like to destroy your sounds, give it a try on drums and you’ll be amazed!!).
And it's free.... so HAVE FUN !
