You're absolutely right that a 'normal' implementation of swing would allow  
for triplets to be evenly spaced. I always forget about that sublety when I  
talk of cams and stretchy rubber bands !

So to clarify - the factor between 0 and 1 is not a global effect - it is  
decided on a per-note basis. This function could be known as a 'strategy' -  
uniform displacement is one strategy, only swinging notes beginning and  
ending on swing boundaries like eigth notes is another strategy.

To have a global factor would be redundant, (though I wouldn't object to  
it) as that basically amounts to a modification of the map to be less  
warp-y.

I just looked at some of the C++ that performers are implemented in -  
hanwenn's right that it'll be relatively tricky. Hanwenn - or anyone else -  
how should i learn how to write a C++ performer ?? As nice as our spec'd  
out solution is - I'm afraid it will just die unless some C++ work gets  
done on 'em...
