Elektor Formant Modular

Hello!

I'm new to the group so I start with introducing myself.
I'm JohnnyBusca (real name: Jeroen) and I live in the Netherlands. I 
love modulars and own several including two formants.
A very beautiful (and heavy) yellow formant 'Asian' (look in the 
photo album), with original elektor modules. The other one has some 
original elektor modules plus some custems including a CEM3340 VCO, 
CEM33x0 voice board and a CEM3320 VCF. Furthermore some comperators 
and ARP stylish type of envelopes.
The CEM based modules do sound very good, but are not typical. They 
sound very much the same like the Doepfer VMS or Bohm Soundlab 
(http://www.tonyblack.org/bohm) which are also based on these chips. 
Therefore I'm using the original elektor VCOs much more.

Best regards,
JohnnyBusca
