However, if you wish to invert the phase for a given partial, simply prefix it with a '-':
sinesum 256 1 -0.5 0.333 -0.25
for instance - each negative partial is flipped 180º.
(Too bad there's no way to make intermediate phases with such a simple statement - you'd have to do that by hand with a counter & a formula.)

does sinesum automatically offset the phase of each partial by 180º?
No, every partial starts with phase=0. You can see for yourself with:
sinesum 256 1 sinesum 256 0 1 sinesum 256 0 0 1 sinesum 256 0 0 0 1 sinesum 256 0 0 0 0 1 etc.
sinesum is just a sum of sines. ;)
