Ged the mod player source and you should find the 'documentation'. If I recall correctly there is a check on the expected file length (number of patterns, number of samples, length of samples) and the actual file length - if the actual file length indicated that it was using 'half' samples then it was treated as such...
The reason for chopping down to 4 bits was indeed 'compression' for the unused bits - note that the SAA(I can't even remember its number) actually only produced 3 bit samples... the lowest bit did nothing, so they could have been compressed even more...

I had already done that - one of them wasn't quite so easy to find. I'm more interested in converting in the other direction. From the sound of it, writing a converter would be a trivial enough task. I'd also like to check all of the modules to see which of them have any 4-bit samples. AFAICS, all I'd really need to know is where each sample is marked as being a 4-bit sample, and which nibble comes first in the sample data. Cheers, -- Stuart Brady
