What is dumb about this policy is it will impact sales of new and second hand IK multimedia hardware, word travels fast and I won’t consider buying any IK multimedia products until this policy changes. ### 4/5 — Garage band *2021-09-08* Hey I’m a big fan of this synthesizer and I was actually really excited when I saw haw good it was and how much it had. I tried to bring it into GarageBand and it didn’t show up. Is this app not compatible with GarageBand? The app feels a bit out of use if I can’t use it in my music production. Also is there an alternative to unison in this application? ### 1/5 — Doesn't work on iOS 9.3 *2021-08-16* I have an old iPad 2 running 9.3.5. When I saw that the editor was compatible with my elderly iPad I was delighted. However, it is either not compatible or there is a bug. As reported by another reviewer the app crashes on startup. Very disappointing. ### 3/5 — No Midi out? *2020-02-15* Maybe a bug? It doesn’t send from the editor to my Uno synth (also true for the drum app). It will transfer presets (yay!), but when I manipulate knobs and sliders there is no response from the synth. Everything is up to date including iPadOS, firmware, and I am using the apple USB3-lightning connector (powered). I’ve tried using midi I/o with my interface (Zoom U-44), also using a USB hub (powered), I tried attaching a hub via the USB3-lightning (unpowered apple brand), different iPad (2017 10.5” pro), etc. Maybe iOS bug? **Developer response:** It sounds like you may need to adjust some settings. Please reach out to our support team. They will help you get the UNO Synth and UNO Drum to communicate properly. https://www.ikmultimedia.com/contact-support/ ### 1/5 — Don’t waste your time *2019-08-22* Broke right out of the box! **Developer response:** We are sorry to hear of your experience with the UNO Synth Editor.

Not either of my iPads though; presumably because being older than 12 months old their OS is out of date. Disappointed that is the case. On my phone it works very well considering the small screen.. And at least allows access to those hidden parameters. ### 4/5 — Love my Uno *2019-05-09* Got the Uno back when it came out. The editor makes creating Patches simple as well as Loading and Saving them. I keep my patch library in the cloud and it functions well with that as well. Hoping for Mass load and save of Patches as well as a Song mode to let you chain patterns. Even if it requires use of the Editor to do the chaining. ### 1/5 — Ipad2 crash!?! *2018-12-22, version 1.0* Ik staff please upgrade to work on ipad2 ## Frequently asked questions about UNO Synth Editor ### What is the UNO Synth Editor app?
