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. 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.

MIDI keyboard required for standalone app. GarageBand is recommended to setup MIDI Bluetooth keyboard via Advanced Settings.

I heard about this app coming out for iOS a few weeks ago, and have been looking forward to its release. It is definitely not fully functioning yet, but the basic “Oberheim” sound is there, and when it’s complete, I’m gonna use this one a lot. I’ve been longing for something in the Oberheim/Prophet vein with AUv3, and this one will fill that void. I am not sure why the developer put it out in this unfinished state, but the description says updates are coming, so I am choosing to support it. I have the OB-Xd on my Mac and it is fantastic; hopefully the iOS version will live up to that potential.

Thanks for the detailed review. The app needs fine tuning indeed, but it's also being sold for a special intro price as well. Thanks again for your support purchasing our products.

Interface is jacked on iPad Pro

The knobs don’t line up at all with the display yet. Hope my money was a decent investment in the future. Really not sure why this is in the store right now.

Developer Response ,

App is working with 2048-by-1536 screen resolution devices only for now: iPad 9,7 and all mini modes. Next release 1.0.2 (coming very soon) will display controls correctly on every model.
