Then why do we? Does all their music fit essentially one time signature, albeit not a signature in the sense of what we call a signature?

You could write it as two measures of 6/8 (and its often done), but then the cells fall on alternating measures. It seems better to some to "translate" the structure so that the 4 main beats and the two cells fall into 1 western measure. > > You also have to consider that the 4 main beats can be subdivided into triple pulse (3 per main beat) or duple pulse (4 per main beat). 12/8 works well for the triple pulse at least. I think that's what you are pointing to with your comments about GCDs.
Actually, I was talking about true 3 against 4 (western) rhythms, or whatever it is called. I thought you meant that people use 12/8 for that now. But you are saying they use 12/8 for this type of music in particular. Not perfect, but the best that can be done under the circumstances, and a musician would still have to be familiar with the music to actually get it. If I saw examples (which may have been in one of your links) I could follow the details better.
