If you email support@eventide.com with the following info we could help you resolve the issue: - What version of iOS are you using? - Are you using the app as a standalone or as an AUv3? If AUv3, what host app are you running it inside of? ### 4/5 — Keeps crashing in AUM *2020-06-16* Love the app, sounds amazing, but having consistent issues with it crashing in AUM and having to be closed and reopened, sometimes multiple times a session. **Developer response:** Hi, please contact us at support@eventide.com and we can look into the issue for you. Please let us know the version of iOS, AUM, and if you are using IAA or AUv3. Steps to reproduce the crash would also be helpful. Thanks! ### 5/5 — refund for CH? got single plugin then saw bundle *2024-06-18* hello Eventide, how are y’all? I bought the crystal harmonizer then clicked on other apps y’all sell & saw the bundle & bought that to get your other amazing plugins for just $5 more - would it be possible to get a refund for the single crystal harmonizer purchase? would be much appreciated. Thanks, B. **Developer response:** Hi, Apple credits customers for apps they've already purchased within a bundle. So, the cost of Crystals should have been credited in the price you paid for the bundle. ### 5/5 — Trippy and Cool *2023-12-08* Very nice when you want some crazy sparkle or something that sounds nothing like the instrument you’re filtering. For appreciators of the non-essential freak out plug in. It’s not a must have but once you got it, you’ll want to use it a lot. ### 5/5 — Insane *2021-05-06, version 1.0.9* Great. Just listen to some demos and you’ll be downloading before you know what’s happening ### 5/5 — Eventide Quality *2020-11-23* I have used eventide hardware in my live set up for years, never thought that I would be getting it on an iPad. This sounds absolutely amazing, lush and warm.Remember, you can do three things, and you don’t necessarily have to do them all at the same time. Yes, it makes a great shimmering special effect, but you can also use it for more simple tasks like just pitch shifting a voice, or putting a bit of that reverse reverb/delay tail on a melodic instrument. Versatile and useful in many way, I use it in Audiobus, standalone, and Auria, functionality is fine. ### 5/5 — Dear Eventide *2020-10-17* The app is fantastic as USUAL with you guys. Thank you so much for the super quality! One thing though: The ribbon controller on this one isn’t working, the ranges can not be set. You can try it out and you’ll see that attempting to modify the ranges in the same way it is done in pretty much all of your apps simply doesn’t affect Crystals’s ranges, those are simply un-settable right now. Hopefully you can fix this soon! Cheers ! Eventide is fantastic 💜 **Developer response:** Hey, thanks for the report. We have a fix for this and it will be released shortly. ### 5/5 — UPDATED - 5 stars, it works - deleted n re-downloaded. *2020-09-08* So I previously found this problematic, could only get toots and beeps, it seems Sky wifi hub was permitting apps to download but they were corrupted - hub now died, me on iphone tether, deleted Harmoniser and re-downloaded, and AU works in GarageBand, and standalone good too. I will contact the developer direct to ‘un-complain’. Now it is working in a sensible way, some of the possibilities are already apparent, it obviously has some great augmentation for whatever input you send it. My faulty wifi hub editing chunks out of an app that is being downloaded, I have never known such a thing! Patently nothing to do with Eventide, this was an obscure technical fault intermittent in nature, to do with broadband comms. ### 5/5 — Astral toad *2020-06-10* Simply WOW. ## Most praised reviews (3 highest-rated) ### 5/5 — Effin Bananas! *2020-06-09* This ish is the bomb! Love eventide you guys are animals! ### 5/5 — iOS game changer *2020-06-09* Turn one synth track into an orchestra/We are Eno now/Just do it. ### 5/5 — Awesome *2020-06-09* If you have to think about buying this,you better skip.It is just another awesome app in the Eventide IOS series.Thank You devops team!!!!!!! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
