Thanks all of you, I'll go for the A130 (after trying the A134, cos
this is a double VCA as I understand).
For the others modules of my first modular I have choosen :
1 VCO RS95 (A Sys)
1 VCO-SUB (A Sol)
1 VCF RS110 (ASys)
1 VCF A124 or A102 (I cannot decide !)
1 ENV A140
1 Slew + AR A170
1 LFO-NZ (A Sol)
and the VCA, of course... some opinions
