The original version, the Buchla 148, was a triangle vco that was fed into a
bunch of waveshapers that gave 10 different partials. Apparently there was
a later version that included voltage control over each output.
Don't know much more than that.

i`ve guzzled my share of coffee and spent my share of time in trance-land
but
no readily "do-able" solution has popped up. years back, buchla offered a
harmonic bank vco ( but with only 6 partials, if i remember correctly ).
i`ve
never seen a picture of one though so i`m not sure what his solutions to the
problem of control were ( even on this much smaller scale). also, seawright
designed one, but as a complete instrument, at either columbia-princeton or
univ. of illinois. was used on a piece of e.m. called "lemon drops" (again,
if i remember correctly) way, way back in the late 60`s.
