[sdiy] Additive Synthesis - phase shifts important??

Your ear cannot tell what the phase relationships between various 
harmonics...however, your ear is very sensitive to a "change" in the 
phase relationship.  Being able to dynamically change the phases as a 
function of time would rate very important to me...(not sure if I am 
going to add that capability to my additive synthesis project or not...).
