OB-Xd - Virtual Analog Synthesizer

OB-Xd is based on the Oberheim OB-X. It attempts to recreate its sound and behavior, but as the original was very limited in some important ways a number of things were added or altered to the original design.

The OB-Xd was designed to sound as good and as rich as the original. It implements micro random detuning which is a big part of that sound. However, it was not designed as a self-contained completely independent soft-synth. It needs to be contained within a VST framework where things like transposition, automation, layering, arpeggiation, etc., are available. Also, like many synths of the OB-X's generation, the OB-Xd has no internal effects so its sounds and textures can be greatly enhanced by the use of additional processing like chorus, reverb, delay, etc.

From the manual:

"Thanks to 2DaT who created this little marvel. But we would be remiss not to thank all the members of KVR who participated in the Obxd forum thread. While the heart and soul of its design and development is all 2DaT, much discussion and debate went into it's graphic layout and the implementation of some of its features."

"So thanks to all who participated in its creation and also to the various people who stepped up to create excellent free patches for the Obxd."

A severely under-rated freebie.

I'm not going to say it sounds exactly like the Oberheims it is emulating, but the spacey, metallic shimmer is there. It's rare for a basic subtractive synth to be able to set itself apart and sound different from others while still being useful.

My go-to for retrofuturistic spacey pads, it has a classic sci-fi sound. It doesn't require much post-processing - just a touch of the clearest reverb you have and scoop out a bit of low-mids and you're there.

The only drawback that it has is the unison-detune being limited to monophony, which is a shame because the unison sounds remarkable in pads.

Obxd sounds great, there are a ton of good patches and banks on KRV and the GUI is large enough to see and use. It's a very usable synth. I love the S&H. Thanks to the developer and all those that contributed patches.

I'm running Windows-7, 64-bit with REAPER 64-bit. I'll try it on the Mac soon.

This synthesizer is amazing; it's a very good, useful emulation of the OB8, from what I can tell, and it has the features I want an emulation of the Oberheim synths to have: clear, lush sounds, easy interface, unison, sample and hold.

The sound is incredible. It doesn't have a sub oscillator, but I haven't been able to tell if it really needs one; you can get the synth to grind low without much of a problem, especially with the unison mode.

There's not much that can be said about the user interface and features; it has a set of filters, the SEM's resonance and cutoff features that seem to be clear enough. (I don't have an actual SEM to compare against, nor am I really concerned about an exact match, personally; I just want the thing to sound good.)

All in all, a very worthwhile synthesizer; I use it with Cubase 7.6, 64-bit windows version, and it works very well for me.
