MIDI In/Out Hardware for DS

Posted schematics, pictures and brief instructions for connecting MIDI input and output to DS to the DSerial Wiki. MIDI output is very easy, because it requires no components besides wire and a 5-pin DIN connector. MIDI input, on the other hand, requires a 3.3V optocoupler because MIDI uses a current loop to prevent introduction of noise.

    Interesting, I may have to try this. There should be a certain MIDI channel to activate the rumble pack… I know if I send an MID ringtone to my phone, there is a special channel to vibrate (for the background beat and stuff).

    Heyo, I am new to modding my Nintendoes. I am curious if this midi setup would work the same for a GBA. GBA comm is just a UART after all, but I dunno if it’s gotta be a specific type of UART or what. Anyone know?

    Very curious to know if this would work of GBA/GBSP/DS, and how well does this midi controller work???

    I am currently looking for a midi sequencer to trigger midi files which in turn would be used to trigger a drum sampler for stage performances.

    I would appreicate ANY feed back in this matter.
    Also curious if you make any hardware hacks for PDA’s??

    Thanks again,

    what a pity I didn’t get me a DSerial2 in time. Are there any plans for a DSerial3? I’ve heard about a Slot-2-solution… That would fit me as I’m currently using a slot-1 card to run homebrew code on my DS…
    If there is such a thing as a waiting list: pleace put my name on it.
    BTW: Your HALO is a pretty cool thing. I’ve just checked out ther flight2 videos and pics. GREAT! A MUST HAVE SEEN THING!

    Thanks Thomas
