I was thinking of relationships like these: 1) Decay time of nth partial falls as a certain formula of n. 2) Frequency of nth partial is slightly different from n * fundamental, by a factor which is a formula of n. 3) Spectrum of nth partial isn't a delta function, but a hump whose width is a formula of n. All these ideas come from physical effects, but you can use them to generate sounds directly, without any physical modeling or AI. My hunch is that could be more such ideas and they could play together nicely.
