As I have approached this over the past years, there are three types
of options:
(in order of complexity)

1) simple and relatively inexpensive:
Get e.g. a Novation A-station, KS-rack or any other VA module and
feed its raw unfiltered VCO signal into a single Doepfer VCF + VCA
module;
I have found the A-101-1 and A-121 to be working quite good for this.
Connect the midi-in of an A-190 to the midi-thru of the module to
trigger an A-140 EG that feeds into the CV in of the VCF and VCA
module(s).
This will give you digital/VA polyphonic VCO's into a single analog
VCF/VCA in with properly synced EG triggering.

Switch off the internal effects of the VA module, and use a chorus
(or one or more of the new A-188-1 BBD's) after the VCA for
modulation effects to sweeten your sound.

2) more "analog like"
Get a Vermona PerFourmer analog 4 voice mono/poly synth module.
It combines great with all Doepfer A-100 stuff.
CV/Gate can be added to this as an option.

3) For real polyphonic analog (like the OB 4 voice):
Doepfer MCV-24 set up in 4-voice polyphonic mode.
four A-110 and/or A-111 VCO's
one A-135 VC mixer (to be used as a quad VCA)
four (identical) A-100 VCF's of your choice.
As many A-143-3 LFO's as you like

The MCV-24 can be programmed to output ADSR signals from its
software which can be used to drive the A-135 and the VCF's

This option is by far the most elaborate and true "poly analog" but
requires a lot of modules and time to "program" sounds.
