Here's what I've been working on for anyone interested
Thought I'd have a go at making a more live sequencer than the other ds apps I'd seen
and use the DSMidi cable hack so I could run some of my new toys without using the laptop as a sequencer
HWTLnG30r3g

Needs to be a bit prettier, add settings screen to change MIDI channel, notes etc. save patterns
another 4 channels would be good with velocities and another page of CC controllers
and MIDI over wifi

the rom

http://beatsnbleeps.com/DStepV2.sc.rar (Supercard version)
u need to make up a MIDI cable tho
http://www.collinmey...sic.com/dsmidi/
and you can load it from a slot-1 device and then swap the flash card for the MIDI cable once it's loaded

any suggestions on improvements/features would be great

I've also been invited to show it off at the next melb dorkbot this sunday if anyone want to come down and check it out

looks like I've been accepted into the nerdfold  :-[

Clever stuff, Jed! And yes, it's nerd to the max, but brilliant to see in action!

[SilverStreak]

HOLYFUCKMEJEEZUS!!!!

That fukn OWN'S dude!

I'm well impressed  :clap: 

[rhythmboy]

Why me take so long to see this?  :-[

Awesome work Jed, so neat and intuitive!

Dorkbot ey? Been to one of their meetings, ooh yer serious nerdage 

Few things nerdier than seeing room full of people laughing at some guy's C++ 'jokes' whilst demoing the latest class routine for his runtime-realtime-thingo-whats it that makes a WAV file go 'beep' out of a gum-stick sound card  :wtf:

awesome jed,  so nerdy . . i love it.

how did you create it ?  is there a DS platform SDK ?

[ijed]

pretty much everything you need is here

download the devkitpro ARM compiler, ndslib and PAlib libraries.
great tutes - the only thing i got stuck on was setting the callback timer so I could get the midi sync working but I figured it out.

and no$gba emulator works good for testing code without going back and forth to the cartridge

http://nocash.emubase.de/no$gba-w.zip (pc only - there's one DS emu for mac but don't know if it'll run this rom or not http://desmume.org/)
and here's the .gba version of DStep so you can run it on no$gba (won't output midi though):

and here's how I made the rough and ready MIDI breakout card for it:

- opened up the Brain Training Demo rom I got with my DS
- removed the chip and components
- soldered two thin wires to the ground and eeprom pins (i got some IDC ribbon cable and took off 2 strands of that)
- soldered the other two ends to the ground and MIDI out pins on a Female DIN socket

I also flattened and trimmed the metal casing on the DIN socket into a T-shape so it fits snug into the notch I made in the back of the ds cart.  Hopefully this will minimise stress if the cable gets yanked on. Also took off the top part of the metal case so you could still open the DS fully.  Bit of heatshrink/electrical tape holds the socket together
Then I just stuck the cartridge back together with some double sided gaffa tape - it ain't pretty but it works

^^^Shift money between accounts at ATMs? One could only hope.

What a hack, eh? Nintendo must be loving this extra interest in their products. Makes me want one now.

you nerds fucking amaze me.

NIIIIIIIIIIIICE!

[zippypinhead]

cool gui, excellent...

what about using wifi like DSMI Midi-over-WiFi library offers?
DSMI website: http://dsmidiwifi.tobw.net/

great stuff, anyway...

still around - just been busy - tons of stuff I hope to implement when I get a chance in the next month (or so...)

Any suggestions feel free to post them up here or get in touch with me

Just DS-MIDI-controller with all 128 controlers will be perfect. I dont like step sequencer (dstar better for me) and WI-FI not working for me. :
