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.

the anti troll

Funny I was talking to people om gearslutz how there's always trolls on vintagesynth who always post and I mean always post in each response group that they got the synth for next to nothing. Seems to make these trolls feel good and they wait for the responses toward them. With a name like Donkey, that says it all. What a coward.

VintageSynth.com has got to get there [beep] together... lol, saying the the OB-X has "Polymod" functionality is a downright falsehood. The closest it has is cross-modulation..... which sounds very different.

You can add OMD to the list of famous OBX users. It's featured on the gear list of their "Dazzle Ships" album.
