Hey this is Magnius here and in this document, I'm gonna list all the voicegroups in Fire Red as well as the instruments each voicegroup can play. But first, what are voicegroups? My definition would be a group of instruments stored in a particular value in a rom. Voicegroups are one of the biggest deciding factors in whether the midi you insert sounds good or not. For instance, if you insert a midi, but you notice one of the DirectSound tracks gets turned to GBSynth, this is probably because the instrument isn't in the particular voicegroup of the song you assembled. This could also be though, because of the GBA's music limits, which are explained in Part 2 of my Music Hacking document. Luckily for you you can change the voicegroup before assembling, but what instruments can each particular voicegroup play? That's what I'm mostly gonna cover in this document. After much research I've produced an accurate list of instruments that each voicegroup can play and if an instrument isn't in that particular voicegroup, it probably won't play correctly.

However, before we move onto that, a little information on how some tracks are used on the GBA. First off, know that every track after 80 is mostly going to transfer into GBSynth, when assembled into Sappy. Channel 81, the sawtooth, is commonly used as the bass instrument in most GBA tracks, although sometimes DirectSound basses can be used if the voicegroup supports it. GBSynth tracks can be used in any track, so if I forget to list them in one voicegroup, that doesn't mean you can't use them. Second of all, I won't be covering what particular drums each voicegroup supports. Also a note to add about track 62 "SynthBrass1" though it says SynthBrass, this track is generally used to make a heavy low guitar sound.

So yeah, that was the list. Next I'm gonna cover choosing the right voicegroup for your song.

Choosing the Right Voicegroup

When the choosing the voicegroup you want to use, you should generally pick a voicegroup that has a lot of the same instruments that are in your midi. For instance, if your midi uses strings, trumpets, but also guitars, you want to find a voicegroup that has all of those. If you find a voicegroup with most of the same instruments, you can either try your luck or change some of the instruments in that midi, so that they're all in that particular voicegroup. If a particular instrument isn't in any voicegroup, it will probably have to be substituted for some other instrument.

But I'm confused, my tracks have different numbers than the ones used on the GBA...

If you have standard midi software, the track numbers are probably going to be different than what's used on the GBA. I don't know if this'll work for your particular midi program but to get the GBA track number, I take the general midi track number and subtract it by one. So say my general midi program has 57 for the track number of the trumpet, it would be track number 56 in the Pokemon games. Your midi program might also have different names for instruments than mine, but it's generally gonna be in the same order. Hopes this helps you guys gain an understanding.

And yeah, that's the tutorial guys... Hoped it help you out.
