Eurorack modular in 1980 by Synton

Synton 3000. This system is owned by Marc Paping. It can be used as a four-voice synth. 
It includes:
Eight 3021 VCO’s, four 3005 EG’s, four 3010 EG’s, four 3017 VCF’s, four 3224 Dual VCF’s, six 3209 dual VCA’s and a total of fourteen 3015 and 3016 mixer modules. There is also a variety of LFO’s, NRG’s, I/O amps, sample & holds and gate processors.Our experience with this system has helped us design the Fenix as a compact, flexible synth that has attenuators and mixers integrated into many of its modules. The Interface module contains a powersupply,  3 jack sockets  wich can be used for input and outputs and a keyboard interface.
