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 very early oberheims (4vs obx) have a richness in the oscillators and filters that's uncommon. discreet components do make a difference. This board actually delivers the promise that was echoed by the synthmakers of the time, that its like having 8 monosynths at your fingertips. this one actually does sound like that.

I've always wanted an Oberheim OB-X ever since hearing one on Killing Joke's albums "Night Time" and "Brighter Than A Thousand Suns". The sounds are so different to those you can get from a Jupiter or any other well regarded analogue polysynth, thanks to the unusual modulation controls. I finally found one in need of restoration, and sold all but one each of my synths, drum machines and guitars. I don't regret it at all - even though the OB-X must be one of the most unreliable and unstable synths of all time, it sounds fantastic. And while you can get samples and software emulations of the OB-X, they can't capture the immediacy of having all those controls to hand on the real thing.

OBX can do FM , VCO-Sync ,Crossmodulation and PWM for pulse and Saw ! . The filter isn't a chip. compared to OB 8 of a friend my OBX blows it away ! and you can control OBX via CV / Gate with many sequencers. OBXa and OB8 doesn't have CV / Gate , FM and Crossmodulation.
