It’s very simple really, it’s indeed 6x DVCOs
I love multi timbrality, it's a shame it's such a neglected feature.
Why not Multi-timbral? - #13 by PeterHanes
For me, AR is a gas killer against this list
Multi-Timbral synths in production and which one is most versatile?
Because manufacturers don’t make multiple outputs anymore 
(main reason I don’t get digi elektrons)
So…
6x DVCOs
Played on keyboard
(Through something to allocate midi notes to multiple channels/voices)
+cheap FX pedal
Then I tried adding a few things on this last tracks, like sequencer, expression pedal and layering samples to the voice.
Thanks so much for all the nice comments, it really motivates me
