repair synthexMAINTENANCE Synthex suffers from common issues:
- voice boards lifespan that is quite unpredictable, fortunately there are not so many custom IC onboard, Synthex is mainly build with TTL and common electrical parts on the shelf.
- maintenance requires patience and experience since there are a lot of circuits inside

lfo RELATED FAMILY

elka synthex reissue

The 2015 Synthex reissue failure.
In 2015 General Music that actually owns Elka brand announced that some famous synthesizers COULD have a reissue! like the Korg Mini-Ms20 or the Korg Odyssey?

Aafter a failed crowd-funding campaign named "Bringelkaback" the Finnish company just gave up on this project- even J.M jarre made a VIDEO to support this funding. Reality is: elka synthex will NOT be coming back... at least not for now.

elka ysnthex 2

SYNTHEX 2- "the evolution of a legend"
The original italian engineer Mario Maggi is working a new digital project called "Synthex 2".
The 2015 Finnish project probably project maybe moved something in Italy since a Synthex 2 website appeared. There are some preorder for now, the machine is probably a full digital VA.

READ THE SPECS from Synthex 2 website.
