[sdiy] Interesting article on top octave generators.

...would be quite prone to suffering entrainment of at least some of the 
oscillators if they are high-frequency and free-running, unless they are 
properly isolated from each other and the supply is decoupled thoroughly.

Why would you make such a comically overcomplicated device with so many 
fiddly adjustments, when you can just spend a couple of quid on an 
inexpensive multi-channel programmable divider?

It makes no sense, and having twelve oscillators that all drift randomly in 
and out of tune would drastically affect the character of the instrument. 
Also, a board with twelve oscillators is far more of a redesign than a 
simple single-chip divider replacement.
