Default mgb midi channel

[Jesse]

I would like to change the default midi channel on the arduinoboy from
1 to 6 so the channels would be:

6: p1
7: p2
8: wav
9: noise

I want to run midines on the out/thru of the arduinoboy and want to
leave the midines channels on their defaults of 1-5.

I looked around in the arduinoboy code but couldn't find anything when
searching for 'channel' that pertained to this plus it would be nice
to have that info on this discussion.

this is for mGB... replace the original function... (I hope this works)

void modeMidiGb()
{
  while(1){                                //Loop foreverrrr
    if (Serial.available() > 0) {          //If MIDI is sending
      incomingMidiByte = Serial.read();    //Get the byte sent from MIDI
     
      //if(!usbMode) Serial.print(incomingMidiByte, BYTE); //Echo the Byte to MIDI Output
      if(incomingMidiByte > 0x7F) {   
        switch (incomingMidiByte & 0xF0) {
          case 0xF0:
            midiValueMode = false;
            break;
          default:
            incomingMidiData[0] = incomingMidiByte;
            midiValueMode  =false;
            midiAddressMode=true;
           break;
        }
      } else if (midiAddressMode){
        midiAddressMode = false;
        midiValueMode = true;
        incomingMidiData[1] = incomingMidiByte;
      } else if (midiValueMode) {
        incomingMidiData[2] = incomingMidiByte;
        midiAddressMode = true;
        midiValueMode = false;
       
        if((incomingMidiData[0] & 0x0F) > 0x04) {
          sendFSByteToGameboy((incomingMidiData[0] - 0x05));
          delayMicroseconds(120);
          sendFSByteToGameboy(incomingMidiData[1]);
          delayMicroseconds(120);
          sendFSByteToGameboy(incomingMidiData[2]);
        }
       blinkLight((incomingMidiData[0] - 0x05),incomingMidiData[2]);
      }
     
    } else {
      setMode();                // Check if mode button was depressed
      updateBlinkLights();

Hello Jesse. It just so happens to be that Mr 80 have given me the
opportunity to take a look at the mGB code. And I needed this feature
myself. So here it is. This rar contains 3 ROMs which each listens to
5 MIDI channels. 1-5, 6-10, 11-15. The channel numbers are printed
above each channel in this version. The fifth channel number is for
the poly mode.
<http://gameboydev.org/files/mGB/mgb_1_3_0-multichannel.rar>

For a future hacked version I'm also planning to let the user set the
channel on the Gameboy, and also make mGB better at co-existing with
LSDj. But that's for later.

BTW, note that this version should be used with the regular version of
Arduinoboy, not with the changes trash80 showed in a previous mail.

Hi,

I'm trying to hook up 2 gameboys (with mgb on each) to 1 arduinoboy, and I would reaally love to have a look at these 3 roms you speak of.

The link doesn't seem to work anymore. Do you still have them lying around perhaps?

Best,
