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.

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

I have an Oberheim SEM Pro, this is a polyphonic SEM/OB-1 (with some xtras) wich I find simply monstruous, poly based on discreete components. That's what many people think the Memory Moog is (wrong), only the OB-X, the ARP Chroma and some upper CS line Yamahas are, AFAIK.
If each voice of the OB-X sounds like a SEM I can't think of any instrument meatier, livelier, warmer, fuller, nicer and bigger sounding. A chord of this must be heaven of organic sounding synths , some quality reverb and I'm sure I could listen to a single chord for hours...
I hope Analogue Solutions release a version.

Nope, that's an OB-Xa in the video. Eddie used it on the album too, he then went out to buy
a couple of OB-8's for the tour.
