OK, this seriously doesn't make sense.
When I copy the file to my Windows computer, the size is Down to 0KB.

I'll try to figure it out, and write back.

Good idea.

I'll try to compress it tomorow, but now I'm tired and will go to bed. It's about 11 PM in Denmark.

Anyway, I know for sure that VocalWriter doesn't have to be running for the file to be expanded, because I've also installed a partition with Mountain Lion, and a partition with HighSierra on the mac, and when I for example boot into Mountain Lion, the file still is 3 MB, and it's also 3 MB after copying it to my external harddrive, but when I connect the harddrive to my Windows computer, it is 0 KB.

Anyway, I'll try tomorow and write back.

Hmm, interesting. Would you mind uploading this 3 mb file so I can look at it? OR maybe the entire zip, that way I can see it in context.
If Awave can't open it, it must be pretty obscure, but maybe i'll recognize something, or maybe as you said, it has to be modified to be recognized by Awave or similar programs.

So, good news and bad news. Bad news: We aren't going to get a soundfont or any other recognizable file most likely. But good news: Opening the gm file you uploaded as raw pcm data does indeed reveal samples that are used for that synth. However, some of them are odd. Some have hiss and subtle buzzy distortion. The piano has odd volume fluctuations. I know that some file formats can have compressed samples that have to be unpacked, so I wonder if these things I observe are side effects of that process. We'd really have no way of knowing.

They actually sampled a doo utterance from Vocal Writer in one of the patches it looks like, which I found pretty amusing.

I wish I could get the sample mapping in some recognizable format like DLS, sf2, pat, or something else. If I knew enough about hex editing and programming, I'd look at the file byte by byte and see if I could figure out how the format stores its mapping information, and somehow identify sample boundaries and loop points. Then I could write a converter to make a SoundFont. As it is though, I know nothing about any of these things. TO start, I'd have to know the SoundFont spec, and that's something I don't even know where to start with, so yeah, it ain't gonna happen by my hands, unless we get a lucky break. Maybe something can be gained from the zip file. My hopes aren't high, but you never know lol

Another thought. I could make a SoundFont by sampling all notes of all instruments. Then I could figure out what's used where and reconstruct the parameters of the sound such as volume envelopes, LFO, sample mapping and other such things. But sampling the entire synth would take hours. I once did it for the Braille Note MPower GM synth and ended up with over 21 hours of data. I basically gave it an m3u list of midi files I prepared, plugged it into AC power so it wouldn't dye, and just recorded it while it did its thing. That probably won't be possible for you though because of the inaccessibility of Vocal Writer and the fact that nothing else seems to be able to access the sound set, but maybe this will give us ideas?

Sorry if it sounds like I'm obsessing, I just love this sort of stuff

First, here is the zip-file.

Secondly
@musicalman: I don't know exactly what you mean by those Things, but if you can make a midi-file with those Things you want, I can convert it to an aif-file with VocalWriter, using sited help.

Well, isn't it worth a shot?

But I don't want to go through so many midi-files, so it would be good with just one file with it all.

But do the 16 hours reffers to the time it takes to make the midifile with all instruments, or the editing after I've made the audiofile?

If it doesn't take much time to make the midi-file with it all, then I'll think it's worth a shot, but I understand if you think something else.

If the audio file would be so large afterwards, I could always convert it to FLAC, which is a lossless audioformat with lower size than wav and aif, and then pack in a 7z-file.

What about Skype or e-mail, you deside.

Ok.

Hmm, Triton was a Korg synth released around that time, but triton is the name of the synth, not the company, unless there's another company Triton that I don't know about. Besides, some of those sounds have a very Roland flavor, particularly some drums and a few other sounds. But I do think the snare drum is from Korg.

You can get the samples by importing ._GMBank as raw data, albeit not in the most optimal form. Not sure what the specifications for the samples are exactly, but I think they're big endian 16 bit PCM.

Cool, Dekyo-NEC2608! How did you scroll through the file and look for text? Do you have some filter for non-text characters or something?
@Slender Yep I knew about importing the file as raw, I did that yesterday. Akse0435 and I are trying to record samples so we can figure out how everything is mapped, but are currently running into hurdles. I'm not surprised but yeah, this is going to get interesting.
