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.
A MIDI keyboard is required for standalone app.
- Updated framework for enhanced stability.
- Bigger switch buttons.
- Replaced LCD font.
- Relocated voice variation knobs.
- Consistent section font size and placement.
- MIDI learn disabled.
Ratings and Reviews
Sounds thick and analogy.
As many have listed, this app does need some updates to really shine, but overall it’s a great early version and the developer seems very attentive to user needs.
GUI scaling or layout redesign for better size of editing parameters, especially on iPhone. Way too small to use (check Moog model 15 for how they do GUI scaling or IceGear’s Lagrange’s GUI side scrolling layout method.
GUI color scheme change options ( want black with blue lines)
GUI button fixes, ( sometimes unresponsive to touch changes)
Perhaps a stronger open style font choice for logo and a more distinct app icon
Settings panel with manual, audio buffer size, and or other useful things
Built in presets and a way to import them
Built in hideable midi keyboard in stand alone mode with midi learn
Blast from the past
I gigged in the 80’s with an OBXa .. I ended burning out its power supply .. won’t have to worry about it with this one. It really sounds great if you have the programming chops. The real OBXa had the ability to layer two sounds which I definitely used .. with this one since its AUV3 you can layer as may sounds as you want by just opening up more instances .. couldn’t do that back then either :) Hope the developer hangs with this one and gives it presets (which the real ones have) and some white pinstripes over the blue background like the real ones :) Me likey this synth. Five stars for sure.
OB xa memories
I’ve never written a review and had to here because this app instantly took me back to my own OB-xa I used in countless sessions here in Detroit in the ‘80’s. I never used presets then and would program from scratch. MUCH easier time pre-DX 7 and digital age. Fun too. Thanks for designing this. I think it’s fantastic.
With Family Sharing set up, up to six family members can use this app.
