Free Synth Emulates The Oberheim OB-X


discoDSP has released OB-Xd – a free emulation of the Oberheim OB-X, OB-Xa and OB-8 synthesizers, for Linux, Mac & Windows. 

Here’s what they have to say about it:

While not copying originals, some of the features were taken to a better point. Continuous blendable multimode filter (HP-Notch(BP)-HP in 12 dB mode and 4-1 pole in 24 dB mode). 32 and 64 bit versions included.

Thanks to 2Dat for the original Ob-Xd and Soshi Studio for giving the rights to continue this wonderful product.

OB-Xd is a free download from the discoDSP site.

    1. Which is actually SEM based, not CEM so there might be the reason. Also, I have an OB-6 and tried this plugin today. The plugin sounds great… for a plugin. Go to the lower and higher octaves and there is a huge tone difference. Also, the SEM modules in the OB-6 drift really nicely by themselves. Not to mention the X-Mod section and audio-rate LFO that the plugin doesn’t even attempt (very few plugins can do this with moderate success).

        1. Actually those 8 pots in the Voice Variation section only adjust the panning of each voice, not drift. If you look at it using the classic skin versus the striped one it is labeled more accurately.

          1. oh, according to the manual the Spread knob “detunes every single oscillator by a random amount, simulating the sound of slightly detuned VCOs”. Kinda similar. Also the Sonic Projects OP-X does have a detune per voice function which works great if that’s what anyones looking for. That one also has variations per voice for envelope lengths, pans, and filter cutoffs. Sorry to blow up the comments.

      1. The OB-Xd does have an X-mod function and the LFO gets right up near audio rate though i’d guess they don’t sound anywhere close to what the OB-6 does. Still, the X-mod does add dome nice coloration to the sound and the LFO does seem to offer high amounts of modulation to get it into some weird territories.

      2. Even if this tonal difference in the higher and lower octaves is true, it is still an outstanding and great sounding softsynth. Oh, and it is free.

    1. Uh, because some of us don’t feel the need to spend thousands of dollars to achieve a sound that is good enough for us. I’m glad you’re not fooled, you are welcome to spend your cash as you see fit. I’ll be busy making music with this awesome synth.

  1. This thing sounds great, +1 to the positive – somebody did a solid job making it, it covers the ground of my recently departed OB-8 nicely (I get that this is supposed to be an OB-X, thanks) and sounds distinctly different than Arturia’s SEM and Matrix-12 offerings, just as you would expect in the hardware world. And you obviously can’t beat the price…big thanks to discoDSP for this!
