0x06 for LSDJ MIDI out, not 0x05.

Bear in mind that while force mode = 0x01, pressing the mode button won't do anything.

It's not *not* normal, but those aren't the default channels. Defaults are PU1 = MIDI channel 1, PU2 = MIDI channel 2, WAV = MIDI channel 3, NOI = MIDI channel 4.

However, the teensyboy firmware loads values for the output channels (and a bunch of other stuff) from EEPROM, so channel 16 etc. must be stored in EEPROM for some reason.

One fix would be to open Arduinoboy1_2_3_teensy.ino and edit:
  boolean alwaysUseDefaultSettings = false;
to read:
  boolean alwaysUseDefaultSettings = true;

Then recompile and upload to the Teensy.

That's assuming the default channels are what you want.

pselodux, post back about what Symbian music apps you find! I recently had a go at installing Syntrax by Klaar - their site is long gone but managed to locate a .sis file. Sadly it failed to work on my Nokia E63.

Am I supposed to add copies of the lib mods instead of overwriting them?

I suggest first backing up the original usb_api.cpp and usp_api.h, then replacing/overwriting them with those supplied in Arduinoboy1_2_3_teensy _Rev_2_2.zip.

Also, post the specific error message.

Also, always faced the problem of unability to write down music that I would like to record once.

Don't know musical notation? Get a recorder, any recorder, your phone or whatever. Press record and sing, hum, tap out rhythms. You'll have at least a sketch of your idea that's better than no record at all.

Is it bad to use several grounding points for a device? Especially when it comes to input and output?

It's not bad, it's necessary. If the devices in your signal path don't share a ground reference, you're not gonna get a good audio signal. The 'better performance' you describe is probably a result of signals being greatly attenuated.

GBC link cables I've bought off ebay recently have had 7 conductors including one for the shield - hope you get the same ones!

On closer inspection, the note numbers are explained in the cheat sheet. Check out the yellow table on the left.

Can I just ask what the scale notes column means? I'm not a musical theorist, i understand the last column cos its in LSDJ language, but that one is a little confusticating

The numbers in the scale notes column refer to which notes of the major scale make up a chord. So a 1 is the 1st note of the scale, 3 is the 3rd and so on. If the note number is preceded by a 'b', it's flattened, or shifted down one semitone. If the note number is preceded by a '#' it's sharpened, or shifted up one semitone.

For the C major scale it would be
1=C
2=D
3=E
4=F
5=G
6=A
7=B
8=C
and so on.

Hey,

Try holding B and pressing A as discussed in this thread: http://chipmusic.org/forums/topic/14923 … weirdness/

Great stuff! Looking forward to having a go with it.

I would say that A stands for anode. So its negative

Even if this is right, then it's wrong. Anode is positive.

Simplest way to test - apply a voltage, using a resistor in series.

Fresh batteries?

This diagram?

The wiring for A0, A1 and A2 is correct. However you should also wire the ground pin of the Arduino the ground of the Game Boy, which is not shown in your diagram.

Try checking your wiring for MIDI IN and OUT ports. The Max patch needs both in order to work correctly.
