### 5/5 — The dev is really great !

*2026-05-27*

Such a great app if you’re into frequency stuff and/or ambient soundtracks - infinitely tweakable!

### 1/5 — Too many restrictions on the free version

*2026-04-23*

If you are going to a make a demo version of the app it should be fully featured save for preventing preset saving and even AUV3 use which are acceptable trial restrictions. But this game of siphoning off features here and there makes it unattractive and prevents the user from knowing the plugin’s usefullness. I was going to try it out to see if I might want to buy it, but when I discovered I could not even connect my midi controller without the pro version I gave up. You would do well to offer this as a paid app from the start or make a more limited fully functional free version (say with 8 lanes instead of 16) rather than playing this feature withholding game.

**Developer response:** Thanks for taking the time to leave detailed feedback — I completely understand your perspective.

In version 2.0, MIDI input is now enabled, so users can try the app with external MIDI controllers before deciding whether the Pro features fit their workflow.

The Pro features help support the continued development of the app and future updates. Apps like this are often created by independent developers rather than large companies, so finding the right balance between a useful free version and sustainable development can sometimes be challenging.

I truly appreciate the feedback, and comments like yours help improve future versions of the app.
