I guess I've encountered some of those particular time representation  
articles, which is why I worry about it ;  )

I agree there is a wider debate that could take place, and it would  
be nice if we trying to implement a variety of rhythmic models using  
various SC mechanisms to see how easily supported/natural within a  
given representation they are. You may well be able to persuade me  
that I'm worrying unnecessarily.

Just sorry I haven't got time to look more closely right now.

Anyway, some fun literature below if anyone is curious about how  
tempo in beats and time in seconds might interact... bbcut2 partly  
implements the 'novel representation' mentioned below that arises  
from Jeff Bilmes' work.
