Nintendo DS MIDI port

nintendo DS midi

[therain] has added a MIDI port to his Nintendo DS. It’s just a two wire connection so it’s pretty easy if you’ve got an extra cart laying around. As a demo, he wrote a program that uses the touchpad to act as two Control Change devices. One is the X value and the other the Y so it behaves similar to the Korg Kaoss pad. He’s working on a sequencer as well.

    MIDI hack ftw!

  3. steve says:

    sweet! wish I had the stuff to build this today.

    Ah, I see that steve’s eloquence and cultured behavior has returned.

    Anyway, what I really like about this hack is that it makes a fairly useable synth. Lots of other midi hacks (the roomba one comes to mind) are kind of cool but not too useful. This one could actually work as a small, cheap (if you already have one and fairly cheap even if you don’t) controller. I especially like that it emulates something a little more exotic than a simple keyboard style synth which might make it a useful addition to someone’s already existent midi setup.

    Pretty nifty all around. I wonder if the author will develop other interfaces for it… with a touch screen the possibilities are almost limitless. Imagine a drum set that you play with a stylus!

    1337. I wish I had a ds to try this on. Maybe you could use it as a bridge between wifi (some DSs have it) and a stero system.

    This is probably the thing that I am most excited abotu in DS homebrew. These things just scream hack me. I cant wait till you can use them like wireless Kaoss pads.

  8. grayskies says:

    damn, i spelled about wrong. :(

  9. craig says:

  11. steve says:

  12. ravuya says:

    Awesome, I didn’t know a MIDI port was so easy to add to things.

  13. Max says:

    midi should definetly be added to more things

  14. Fragged says:

    Maybe you guys could implement a hashed IP or just give us steves IP so we could mess with him + identify forgeries :-)

  15. bp says:

    Kind of a funny question, the possibility of someone being impersonated on a public, no registration forum.

    So lets say that someone does impersonate steve… do they have any less claim to stevie-ness than anyone else? Is the steve that exists now even the original steve? Since we often don’t know which post comes from which steve, our perception of steve has become fundamentally severed from any material reality. Steve is now only symbolicly an individual.

    Indeed, the open framework which undergirds the comment section makes us all symbolic creatures because there is no nescessity that what we say in this space has any correspondance to a single physical creator.

    The impurity in such logic, of course, is that if the various steves were to disappear so would steve, he does not truly “stand alone” so to speak.

    lay off the pot dude

  17. David says:

    Steve is a standalone complex, the original steve does not even have to have ever existed, because the steve copycats will not let him dissapear, steve refrained from posting, and yet their were numerous steve led posts. Now I am only taking steve’s word that he has not posted, but it seems like he is telling the truth on that. steve is no longer a person, but an idea and that is going to be a problem that will haunt hackaday for years to come. too bad Hackaday does not have the ability for an avatar, then there would be a symbol for steve, and i guarantee that eventually there would be a tee shirt for steve and the hatred of leds. Anyways Nice hack, makes me wish i had a DS.

  18. I think David has been watching too much Anime (Ghost in the Shell much?)

  19. bp says:


    Probably not a bad idea

    The symbol would read: “I thought what’d I’d do was I’d pretend I was one of those deaf-mutes.”

    Interring if DS or PSP is getting more mod-hacks like this. I have a feeling that hacker community likes Nintendo more.

  21. the sixth says:

    cool black ds.
    kraftwerk nonsense

    You asked for a PSP midi hack? I just posted mine up at . It also lets you control your mouse all through the wireless connection.
