[PD] buzz opcode

[Frank Barknecht]

Hi,

does anyone know of an external or abstraction that behaves like the
buzz and gbuzz opcodes in Csound?

If you don't know [g]buzz, they output a set of harmonically related
[co]sine partials. I tried simulating this with sinesum arrays and
tabosc, but the interesting part in buzz is, that one can change the
amplitudes of the partials at control rate. But changing the array while
running the wavetable oscillator in PD is not an option, as it gives nasty
glitches.

Thanks for any pointers,
