[sdiy] Stretched harmonic synthesis

[cheater cheater]

I was wondering if anyone knows any ODEs which generate a signal with
harmonics which are progressively stretched? Meaning higher partials
are further apart.

Or alternatively progressively contracted - higher partials are closer together.

Are ODEs the only kind of differential equation that can be solved
without a delay line?

Thanks
