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."

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.

An important information which is desperately lacking in this page:

OBXD works also perfectly well on OS X

HEy all, is there a patch or anything that would allow automation on ableton for this? cant find anything.

I'm setting up a new DAW computer (Win10) and i can't remember *where* to install the OBXD preset banks. Also can't remeber how to access the presets from the OBXD UI.

Sorry for silly noob questions, but haven't been able to find where i learned this info in the first place.

There is no 'set' place to install the presets.... just install them in a folder of your choice (I put them in a folder called 'OBXD Patches' that gets backed up nightly so they don't get lost), then after loading an instance of OBXD in your DAW, go to the VST2 drop-down menu and choose "Load Bank..." or "Load Patch...". Navigate to the folder where you installed the patch banks or patches, choose the bank you want, and it will load. The next time you go to the "Load Bank..." menu, it will default to the last folder you opened. Remember to Unzip/extract all your banks.

This software to be perfect just need an interface to access the FXB and FXP.

What's the use of the AU presets? How can be loaded?

Are there any Styx fooling yourself or Sail away patches?

I was only able to download the windows version via the linux download button. ...And so my battle with OBXd begins again! This time I've returned stronger, smarter, faster.

Is it only Mac version? Click on "Win" icon and downloading installer for Mac.

Links should be fixed now.

Is there a 32-bit version for Mac?

Thank you.

I copied VST to my PLUGIN folder of Ableton. It works but the window of the plugin isn't the full view and there is no option to scroll to some features. Anyone can help with that?

Where is the source for the current release? Last update on github repo is from 2014, while the 1.4 binary release is from 2017.

Yes I'd love to get the latest sources as well.
