GlitchDS is a homebrew Cellular Automaton music sequencer for the Nintendo DS. It is for creating IDM and Glitch style loops. R4DS is required for using this application.


  • Customizable Cellular Automaton sequencer.
  • Create your own “trigger points”.
  • Load in your own sounds.
  • Save and load your work.
  • BPM settings, or “strum mode” for controlling tempo.
  • Up to 6 sounds can be loaded at once.
  • Each sound has its own 32 step frequency modulation sequencer.
  • Global Distortion setting.

User guide

glitchDS is organized into different pages.

  • Sequencer Control - It has a 32 step sequencer based on the Game of Life. After 32 mutations, the sequence starts over.
  • Trigger Config - How does the sequencer know when to play a sound? Triggers! It specifies what should happen when a node on the sequencer graph changes from 0 (black) to 1 (white).
  • Choose Sounds - You can assign a sound to one of the swatches (otherwise known as the little colored boxes at the top of the screen).
  • Clock Control - Allows you to set the BPM (beats per minute) of the sequence playback. The BPM is approximate.
  • Frequency Modulation - You can modify the frequency (pitch) of each sound via the frequency modulation page.
  • Distortion Settings - A rapid fluctuation of the sound's frequency.
  • Save/Load - Save current song along with all settings.

Further details can be found from the official site.
