more analogue additive (fwd)

[List, Christopher]

Maybe I'm missing something simple here, but how does one easily
generate a triangle with a period _other_ than F^n Hz, where F is the
fundamental? I mean, I've forgotten a lot of my theory on audio waves
and stuff, but don't you want to add up waveforms with a period of F*2,
F*3, F*4, F*n... ? Simply doing FWR on the triangle wave won't get you
those waves...
