A massive thank you to the developers, worthy of ⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️ I really can’t believe the lack of reviews for this absolutely underrated powerful iOS synth. This and the awesome Discovery AUv3 are so powerful and immensely satisfying to play, they both sound so crystal clear. Two of my best purchases for sure. 27-August Just when I thought I had enough analogue synth apps in my collection, OB-Xd appears, but this one is superb and extremely usable. ### 5/5 — Great App! *2026-04-07* Hello, I love this plugin and I constantly use it on my singles and albums. I’m reaching out in hopes that you guys will create another Oberheim AUV3 plugin? One that is of the older version of the Oberheim? thank you for this app, it has been such a tool in my music. ### 5/5 — Update *2026-02-16* Runs now both on iPad and iPhone. My favourite synth for most sounds, apart from bass. I would add a sub oscillator in the empty mixer area then it’d be perfect. ### 4/5 — Need to be able to save presets *2025-08-02* I like the sound of the synth and the controls. Always wanted an Oberheim synth back in the day. It would be really great to be able to save your presets within the app. Please add this feature. ### 3/5 — Top - except! *2025-03-13* Been working with synths over 45 years. My Oberheim Xpander from 1982 has far better midi implementation than this - which makes a FANTASTIC synth almost unusable. Running as an AU it's midi mapping is completely unstable. Program changes seem to be Omni. I mean for decades Volume has been CC7 on this it's 71. Why? ### 2/5 — A problem *2024-12-01* I picked this up this morning on a Black Friday sale. I’ve been anticipating this update, really looked forward to getting it, and now it’s turned out to have a serious flaw. I’m using it on a second generation 12.9” iPad Pro, iOS 17.7.2. which is the highest OS version that I can use on this iPad. When using the app in stand alone mode, I’m experiencing severe latency on lots of the patches, yet when I use it in AUM, there’s no latency. I can’t find any adjustments for buffer size or anything. This really needs to be addressed. ### 5/5 — Updates to 5 stars *2024-09-09* With the latest MIDI settings update I give it 5 stars ### 5/5 — Excellent *2024-08-30* Pas forcément le synth que je rêvais d’avoir, et pourtant car avec une belle sonorité riche et "vivante", une interface ultra claire et une banque de presets ultra complète, le résultat est vraiment très convaincant 👍 Le tout pour un prix raisonnable, bref je ne suis vraiment pas déçu ! ## Frequently asked questions about OB ### What is OB-Xd 3 AUv3 Synth?
