EDIT : Forget these modifications below, I just saw that trash80 already implemented a force mode into the arduinoboy code :
in the Arduinoboy_1_2_3.ino there are 2 variables that do the trick (i never tried but should work)
  0x00, //force mode (forces lsdj to be sl)
  0x00, //mode
 
-------------------------------------------------------------------------------------------------------------------
herr_prof, the way i did it was for developpment and debugging purposes, so it may not the most clean way to do that but see below how I did this :

Small Warning : I did that on December so it is what i remember, ideally it would need to be retested .. not sure if i did  not modify some other parts, after a quick look in the code, it should do the trick but to be sure I would need to digg more into the Trash80 code. So test it and check if it's working.

in the file mode.ino you have a "void switchMode()" function which is responsible of choosing the different modes.
in this function i commented the whole switch(..) case, etc.. and added  the function i wanted. see example below :

void switchMode()
{

  modeLSDJSlaveSyncSetup();         // added the mode i want ti run alone

/*    commented all this part below
  switch(memory[MEM_MODE])
  {
    case 0:
      modeLSDJSlaveSyncSetup();
      break;
    case 1:
      modeLSDJMasterSyncSetup();
............
..............
..............

    case 6:
      modeLSDJMidioutSetup();
      break;
  }
*/
}

et voila ..
you don't need to comment you can also delete the switch function but if you want to change your code after it is easier if it's commented ..
After doing that if you use the switch the led will continue to change but every mode change will launch the same mode ...

and again .. a Big tHanks to trash80 for this amazing Arduinoboy ...

If you are tired to use midi with big DIN cables and prefer to use usb midi, don't hesitate to test teensyboy, the arduinoboy on a Teensy :
http://noizeinabox.blogspot.com/search/label/teensyboy code has been released but need testers because i'm not a expert with LSDJ,Arduinoboy,mGB, etc..

Hi,

never tried with the hex file, but if you use arduino IDE with the source code, there is some important step that you need to do before :
to use the realtime midi data you need to upgrade the teensy core  : http://little-scale.blogspot.co.uk/2011 … -beat.html

before compiling you need to choose in arduino IDE> tools > usb type >midi
And to be sure you are sending correct midi realtime data, maybe try with another software like Midi-OX to send the clock.

Did some quick test with the Arduinoboy version of LSDJ.

getting good results with livemap mode.
but getting strange results with Midiout. It seems that these probleme are coming from a misunderstanding on how midi out is working. Just saw 1 hour ago how to use it using effect command NQXY. Will continue testing tomorow.

If someone is using a lot this mode and want to give me a little .sav with a small song to test, will be happy to do because my knowledge in LSDJ is quite small.

Just posted schematics on my blog : http://noizeinabox.blogspot.com/2012/12/teensyboy.html

TeensyBoy is using USB Midi, that why i'm currently porting Arduinoboy on a Teensy (becoming a TeensyBoy). When you plug Teensyboy usb port it is viewed by your computer as a midi device automatically.

Hi,

you can even put a Arduinoboy inside if you have some place.. not exactly a Arduinoboy but a TeensyBoy (port of arduinooboy on a teensy) which use usb midi.
You can look here : http://chipmusic.org/forums/topic/9337/ … teensy-20/
The code is nearly finished but just need to test livemap and midi out mode on lsdj (don't know how).

Hi,
Thanks for the clarification
Do you know where I can get it ?? ( I already have a lsdj account)

Thanks in advance

looks like you are doing this ...  : http://www.instructables.com/id/Arcade- … ontroller/

but midi is sent over usb in this project. not via a midi din connector.
