dSTAR sequencer is a MIDI Music sequencer for the Nintendo DS. It inherits and expands upon functionality from famous x0x style sequencers of the past, and the present including the Elektron Monomachine and the Radikal tehnologies Spectralis. In contrast to these two sequencers, dSTAR is available as free software for your Homebrew Enabled Nintendo DS. For MIDI output it relies on a dserial device (see http://www.natrium42.com) or a wifi connection to a PC using libDSMI (see http://dsmi.tobw.net/).
