I agree! That's what I meant before. 

Anyone has an idea how to 'phaselock' seperate VCOs? I can't imagine since
normal sync-options just reset the wave and produce all these wellknown
artifacts creating all the famous 'sync-sounds'.

Since Fourier expects strict integer multiples of the 1st harmonics frequency 
as it's overtone frequencys I can't imagine that any system with independent 
oscillators could do this in this sense. This is strictly something for the 
digital domain where it's often named diadvantages are a must to achive usable
results IMHO.

On the other hand it can be pretty interesting using lot's of VCOs and VCAs 
to create additive sounds. But they hardly would be reproduceable (depending on
the system). I tried this with my Yamaha TX816 (which is a digital system as you 
know) but even the offset caused by MIDI-delays are enough to distort the sound.
But it was an interesting trial :-) (I was using 8 x 6 operators in parallel. 
Then I was trying to use even single notes which would allow me to use 16 x 8 x 6
operators using MIDI-notes but this was too complicated and produced one static
sound which couldn't be transposed.)
