### 3/5 — Help

*2025-04-04*

I love this app, but it has only worked 1x for me on AUM-which I use because I am not recording, just creating pre-sets within all of my apps(almost every one in the app store-over 500 so I have experience with these, the problem I dont think lies with me, yet I hope it does?). I can't get it to work anymore. Only the delay works at this point and 1 oscillator obviously. Contact me please. I dont know if I can put my info. on thi site and I can't see a way to access you on your web site. Just a video, which is unnnecessary for me.                                                  For you who want to check the app out I will give it 51/2 Stars. The envelope generator alone would be worth it to me, I have never heard an Eg so clearly s this one and a guitar pedal I had called The MUTRON 3(back in the day). The Lfo is Big and Unison turns everything into a Giant Roaring at you when the Ring Modulator is doing its job. Then you have a limiter to do whatever you want with and finally a great delay. I quickly got some Bombastic pre-sets out of it. I would like it back and then I will set out to buying more of these apps

### 5/5 — Phenomenal

This is the eighth Jax AUv3 I’ve purchased and as with all the others it is a phenomenal and invaluable tool for manipulating sound. 

One minor criticism is the lack of presets. I typically draw inspiration from factory presets by starting with sounds I like and thoroughly destroying them, nevertheless, the demo YouTube video does an excellent job at showcasing the apps potential and offers a starting point. 

I really don’t understand why Jax isn’t mentioned more often in the iOS community. They’re on par with Audio Thing, MOOG, Unfiltered Audio, and Sugar Bytes imo.
