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.

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.

What’s New

Version 1.16

Resolved an issue where the Bend Octave button MIDI CC was being overlapped by another parameter. This has been rectified by reassigning the MIDI CC to number 32.

Mostly perfect

Ever since I was a kid, I was obsessed with the sound of the Oberheim Ob X series , so I had to get this as soon as I noticed it in the App Store. It is exactly as awesome as I hoped for…mostly. I know the GUI has been optimized for the iPhone now and is much improved from earlier versions. There is one issue though… when using it as an AU in GarageBand, I can not access the last two banks as if I try to scroll down , the bottom two banks are cut off, and one of those banks is the empty one for user presets. Now the work around for the other is to enter standalone mode, choose the preset and hit “copy” load up a “default” preset in one of the few accessible banks that have one, and then hit paste in the menu. The tricky part is, if you forget to load up a default preset first, you’ll accidentally overwrite the loaded preset. That is the legit only issue I have but it’s kind of a big one

Sound is a 5 , interface .....

Would be fantastic to use skins similar to the VSTi version...layout needs fixing to be nice , also fitting in au3 windowed space better would be great. Needs midi keyboard would be best added to the pics too btw . That said I love the sound engine , the vsti is one of my all time favorites coming from a person who’s used them since model e .

Thanks for the most recent update!

The new scrollable UI is far superior to what we had before.

I haven’t had the chance to fully get dirty with this synth but it looks promising, is not too expensive and is AUV3, that’s mostly enough for me to spend a few bucks on an iOS synth.

The little I’ve used it, I’ve enjoyed the sound too! Now that the controls are far better I will use it a lot more (I’m an iPhone user and the previous UI was a little too tiny to be conveniently set). It would be a blessing if we could also zoom in a little bit, enabling us to use the AUV3 in portrait mode on iPhone on apps such as AUM. This would be massive!

A little heads up about a bug: turning a knob Downwards doesn’t seem to affect the UI Window however turning it upwards does and acts as a drag on the interface. Workaround: touch screen with another finger to keep screen position locked while changing knobs.

Hopefully this little detail can be fixed?

I can’t see a keyboard on the regular app, but I only use AUV3 so to me this is irrelevant (although it did use to have before if I recall correctly, dev it might be a good idea to not remove it from the standalone app (in case you did, I’m not sure)).
