New user of USBBoy and mGB, few questions/issues (Page 1 of 2)

Heyo. I used the USB Boy recently to drive a Gameboy Color with mGB when playing in a funk group. I used a USB MIDI keyboard and had it run through Ableton with the USB Boy to send output to my Gameboy Color. I experienced VERY little note dropping when using the Gameboy Color (has a processor twice as fast as the DMG's, perhaps you should try using a GBC).

I believe the issue of note dropping has to do with how the serial port on the Gameboy works, not something to do with the USB Boy. You might want to experiment with the LSDJ keyboard setting on the USB Boy and prepared LSDJ instruments if you want to do single-line stuff.

As far as the 4-audio out method... not really. It's easiest to prosound 2 Gameboys and use 2 instances of LSDJ with the same song playing (synced one master one slave) with channels panned left and right (pu1 and pu2 on one DMG being L and R, WAV and Noise on DMG 2 being L and R) then sending all of those into a mixer or audio interface. I haven't tried it, but I know that it *should* work. It isn't possible to do a quadruple prosound due to the nature of the Gameboy's synthesis being done in the CPU and mixed down into stereo channels before it hits the amp.

Alas, I was afraid these would be the answers. I just spent a fair deal of money on this DMG, sad to hear it'll need to be dumped if I want to use it for live play. But I suppose I should have read up a bit more.  As far as other models of gameboys go, which would be recommended? I quite liked the Advance SP, thanks to the backlight and portability. Does it need a prosound mod, or is it good out of the box? Also since the USBBoy has a DMG style Link port, and the GBA would of course have GBA style, will I need to find an adapter? Not sure which Id need.

Max editor? and delay settings? Where cna these be found in FL Studio or Renoise?

Read the arduinoboy page for more information about the max editor and it's settings.

i found that when the notes touch each other in whatever daw you're using, that you'll have more dropped notes than if you add a tiny bit of space between them.

the problem comes from the computer sending a midi note off message and then INSTANTLY sending a midi note on message. drag the first note back by like a 128th note so the two things don't happen simultaneously, know what i mean? that helped me a lot.

The max editor works in the max runtime environment independent of any daw.

Maybe the issue is in the TeensyBoy code?

http://code.google.com/p/noizeinabox/wiki/TeensyBoy

mGB mode is listed as "finished and seems working need further tests"?!

Tweaking the value of the line 'delayMicroseconds(100);' in the Mode_MidiGb_teensy.ino file (see below) might help?

void sendByteToGameboy(byte send_byte)
{  
  delayMicroseconds(100); // NIB : delay needed otherwise this function is triggered too fast for the gameboy
  for(countLSDJTicks=0;countLSDJTicks!=8;countLSDJTicks++) {  //we are going to send 8 bits, so do a loop 8 times
   if(send_byte & 0x80) {
       PORTF = B00000010;
       PORTF = B00000011;
   } else {
       PORTF = B00000000;
       PORTF = B00000001;
   }
   send_byte <<= 1;
 }
}

The editor lets you tweak that value directly without having to compile code.
