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.

I had and played this synth live and in the studio for years...one of my absolute favorites to date. Nothing could match it's fatness and warmth. I no longer have it, but have found a great VST of it here: http://www.sonicprojects.ch/obx/welcome.html

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.

Lots of people are speaking about Killing Joke - Love like blood, I love the intro synth in this song !

Can someone explain how to get such a sound ??

I'm totally unable to get such a sound! Which oscillators waveforms, filter, etc. ? Thanks for all relevant info.

Thanks a lot.
