DO NOT BUY THIS. ### 2/5 — Having difficulty getting it to work on latest iOS *2024-09-27* Hopefully developer will address the issues. ### 5/5 — So good! *2021-08-08* I love my tetra and It works really well with the digitone but it’s a lot of menu diving! Whatever complaints people had with this app 7 years ago, it seems they worked them all out. Just plug in and play. Practically no setup required! I haven’t had a single issue and I’ve been using it a fair amount :) ### 1/5 — GUI broken *2021-01-02, version 3.0.0* I haven’t even started programming with the app. But right off the bat, the GUI is broken on my iPad Pro. Completely unacceptable for a paid app at this price. ### 2/5 — Ok *2014-10-01* Works ok, kinda buggy and way overpriced. Just get lemur and make your own editor. ### 1/5 — Unfinished *2014-07-09, version 1.0.1* So far, this piece of software has been no more reliable than this company's desktop software. Right away, there were communication issues between the Tetra and the app. If this app is made to work properly in the future, it will be a great way to program the Tetra. ### 1/5 — Glitchy to the point of frustration *2014-05-14* Considering the hefty price tag of this, I was expecting more. It suffers from serious delayed reactions - press something, think it didn't work and as you go to do it again the previous thing happens. Scrolling the presets with the scroll bar is infuriating. As you see the preset you want and let go, it continues to randomly scroll until the patch you wanted is out of view. Please can we get an update to fix these issues, as for this price I really was expecting a more polished app. ### 3/5 — It needs more work!!! *2013-12-18* This is the best iPad editor for the Tetra so far, but it's not entirely working yet. Three problems: (1) It doesn't remember the program banks that were uploaded in the previous session--if one shuts down the app and opens it again at a later date, one has to reload all four program banks. It would be far better if the Tetra editor could remember the last state it was in. (2) There's a big problem with Combo bank functionality--it simply doesn't work. When I tried to upload Tetra's Combo bank to the editor, the Combo patch names never populated the bank list. If one changes the Combo on the Tetra itself, the Tetra editor reflects the change, including the correct Combo name, but the selected Combo names never appear in the Tetra editor's Combo Bank. (3) The row of tiny little buttons at the top of the editor are too small and finicky to function consistently. Sometimes they work and sometimes they don't. Bottom line: Once Soundtower has ironed out these problems, this will be a must buy for all Tetra owners. ### 5/5 — It works! *2013-12-08* For those of you nervous about spending cash on another potentially buggy Tetra editor, I made the leap and am happy to report that all seems to be going smoothly. Using an Apple camera-connection-kit, the iPad connects to the Tetra's USB port allowing a midi keyboard to simultaneously connect via the traditional midi ports. This editor is very thoughtfully laid out. The individual modules enlarge when touched, making editing the Tetra's complex modulation sources/destinations easier. I'm glad there is finally an intuitive and elegant window into the brain of the Tetra. ## Frequently asked questions about Tetra Sound Editor ### What is Tetra Sound Editor?
