Hey it’s Free! *2025-09-25* Just got this on my iPhone 12 Pro Max and it sounds really amazing! Best part it doesn’t coat you anything! Great job! ### 4/5 — Very Klevgrand *2025-04-22* What I like about Klevgrand synthesizers are the simplicity of the graphic user interface, and the quality of sounds. Syndsphere is a good example. Sounds are manipulated by operating a spherical control to find a timber that one finds interesting. It sounds good as you would expect from Klevgrand. It is an easy to use synthesizer and as a result, the sound palette is useful, but not exactly huge. Well worth investigating. ### 5/5 — Smooth Live *2025-04-21* useful for Live , changing the sounds smoothly. Thank you. And I hope , update , other synth like this interface…. ### 2/5 — A little disappointed *2025-02-21* Usually a fan of klevgrand plugins (but this is my first iPad app by them. )This synth sounds nice when it works. Doesn’t seem very stable as the majority of time now, I can’t even get it to produce any sound at all. Cool idea but no reason for it to take up space. uninstalling now ### 1/5 — Nice idea, but ... *2025-02-06* A lot of the sounds have VERY strong oscillation profiles! (is this intended or is it a bug?) In other words, a very intense pitch warble and (imho) are out of control on some of the sounds and make them totally unusable. Any of the oscillations that control either the amplitude or tone are not as bad, but I would still like to be able to control them. And for me personally, a lot of them are not useful because of that. I see the potential and I like the core sounds and I like the idea of blending between them, but, I need to be able to control the intensity of these oscillations, even if it's a global setting. Two dollars won't break the bank, however I'd hate to see this app go to waste because it ended up in my "great in theory but not in practice" app heap. After all this time … they finally made an update. hoping that they took care of the problems I said above. The only problem is … I only get a keyboard and I see nor hear anything else. (no interface) … Zero! ### 1/5 — Not Useable *2023-01-17* The interface is mostly a gimmick that doesn’t let you save sounds for later or repeat a sound quickly. The sounds themselves are unremarkable and often just bad or cheesy. ### 1/5 — 100% crashing on startup. *2022-10-09* Junk. ### 3/5 — Don't expect this to make "any" sound *2020-08-05* You cannot load your own custom sound or sample, to give it a different base sound. And it can't be used as an AU effect, to modify sounds coming from other apps. So you're stuck with just its one base sound, which I assume is a basic sine wave. It would have been totally dope if it could be used as an AU effect, to modify any sound. That said, it's an inexpensive app. So if all you ever wanted was a buzz or a hoot, with various amounts of wah wah, this is the ultimate app for exactly that. Go for it. ### 5/5 — So simple and lovely sounds *2020-04-20* I love it, lovely sounds and just a delight to play. Thank you 👏🏾 ### 2/5 — Nice idea *2019-07-25* But u need patience. It's like bringing the balls in the eyes of the clown. ## Frequently asked questions about SyndtSphere ### What is SyndtSphere?
