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 have a 6 voice one of these, its had its 12db filter replaced with a 24db self resonating filter which expands the sonics a little more, certainly these are the fatest warmest beasts ive ever heard, capable of earthreal pads,soup thick pads and general wobbly organic goodness and some very unusal x mod metallic osc sync mayhem.
Needs to be mended though as poorly at the moment, o yes and unison with slow filter open is huge beyond beleif.

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!
