Oberheim OB-X
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.
This synth is definitely worth checking out. It has been used by Herbie Hancock, Chick Corea, Cirrus, Depeche Mode, Queen, Supertramp, Kenny Kirkland, Jean-Michel Jarre, Japan, Tangerine Dream, Rush, Simple Minds, Chicago, Styx, Ultravox and dozens more!

Needs to be mended though as poorly at the moment, o yes and unison with slow filter open is huge beyond beleif.

enjoy ;)
Sonic Projects has done an outstanding job in simulating the nuances of the OBX complete with drifting tune oscillators plus tons of stuff that the OBX couldn't do...check it out. If you love the original, I think you will appreciate the VST...I sure do!
You'll need an actual OB-X, as the instability of the discrete components are part of what makes the Love Like Blood sound - and the OP-X software emulator doesn't come close. As for how to get that sound on the Obie, you'll need plenty of pitch modulation on oscillator two, saw waves, frequency cutting fairly low and quite high resonance.
