what "scale" for adding sines for basic waveforms(saw,square

[petterdass]

HI

When listening to additive synths i hear they add sinewaves according to a specific scale, starting with octaves, then 5th and 4ths and then closer and closer as partials getting brighter. Which "scale" is this?
I know that for making saws etc there is also some rules about some amplitube getting inverse propotional to harmonic something... how can i best mimic this with adding sinewave subtracors in reason where amplitube is scaled from 1-127?

Thanks!
