### 2/5 — UI greatly outdated…

*2024-08-26*

…and difficult to use causing one to focus on mechanics instead of music. Too bad as it is versatile.

### 1/5 — Not playable on iPhone 12

*2023-02-09, version 2.91*

Apple’s swipe up interferes. Only supports right handed Landscape mode. Opening Samples window, it overlays the screen preventing a double-tap to close! It wastes screen on the right side. The audio engine still crashes requiring stop/start of app. I did makes some wild sounds but it’s not actually usable on the iPhone 12. Good news that you can record and export aif files. Too bad it’s bad. Deleted. Wasted money.

### 1/5 — Audio engine failure

*2019-06-11*

I have the updated version and still experiencing the audio engine failure just seconds after using the app... please provide a well tested update

### 4/5 — Hidden hyperspace gem

*2019-03-21*

This thing is lethal and besides the clearly labeled limitations, it is a fabulous sounding wavetable sculpting synth. The given samples are enough to mangle with and if you just work with it a bit you get some sweet glitched out pads and washes of sound.
