Oberheim OB-X

Oberheim OB-X Image

The first of the OB series Oberheim synths, this is a classic analog synthesizer available in 4, 6 or 8 voice configurations. It featured a 2 pole VCF lowpass filter with its own ADSR, a VCA with ADSR, a flexible LFO section, polyphonic sample and hold, polyphonic portamento and 32 patches of memory. Although it has been over-shadowed by the bigger and more popular OB-Xa and OB-8 synths which offer more flexible programming, the OB-X still holds its own. Capable of lush analog synth sounds comparable to the Sequential Prophet 5 but at a reasonable price. The OB-X also gives you Polymod functionality, something that the OB-Xa and OB-8 do not have.

Actually, the OB-X features not "Polymod" but "X-Mod," short for Cross-modulation.

Hey RetroSound, thought that you are here with this wonderful synth.
Love your vids on Tube and of course the sound of SEM and the Oberheim OB-X.

thx for the links to Nena, Killing Joke and so on.
Nowadays it seems unbelievable that this Synth was used on stage in that days.

Great Demo Retro Synth...it's clear that the OB-X has the fattest and the more organic sounds of the vintage synths...it's huge and heavy, but as a proud owner, I'm so satisfied with it...thanks for your wonderful demo.

As a matter of fact "Jump" studio version was an OB-Xa, not OB-X. Eddie confirms this in an old keyboard magazine.
