### 3/5 — Free but

*2023-03-01, version 1.1*

User interface so small !!
Unpleasant to play with

### 2/5 — Microscopic UI while a Plugin in GarageBand

*2021-12-02*

As other people have noted in their reviews, the UI of this plugin is extremely tiny when used as a plugin in GarageBand. That really reduces its usability a LOT. I’m already on as large a screen as one can get on iOS: iPad Pro 12.9”.

Also, the inactive controls look disabled. Try a different look, because it’s not fun to assume a control is unavailable when it’s merely unselected. UI conventions exist for a reason.

It is a free app, so, thanks I guess? I’m not sure I will be able to make use of it because of the UI, though.

UPDATE: The developer suggested resizing the plugin in GarageBand there is NO SUCH such facility to do so. If there is, they seriously need to document it on their app page!

**Developer response:** Hello and thanks for the feedback, have you tried to expand the UI in GarageBand? It is fully resizable.

### 5/5 — Very interesting…

*2021-09-23*

To tweak and tune it’s briljant…..thanxxxx

**Developer response:** Thanks!

### 2/5 — Microscopic UI

*2020-09-20*

Nearly unusable as a plugin in AUM.

**Developer response:** Hello, the UI is fully scalable. What is your device model/make?

### 5/5 — オートメーションの代用としても

*2020-09-10, version 1.0*

GarageBandは音量以外のオートメーションを書けないが、これは代用になるので便利

もちろん普通にLFO付きフィルターとしても使える

ただボタンのUIが小さすぎて押しづらい、また文字が読めない
(iPadAir、GarageBand内でAudioUnitとして使用)

### 5/5 — Smashing

*2020-08-09*

Great little app that’s a regular in my creations. I suppose if your having trouble reading it you could always put your glasses on.

### 4/5 — 触ったばっかりだけど

*2020-07-15, version 1.0*

ボタンをスマホでも押しやすくしてくれたらなお良い

### 5/5 — It's free,

*2020-06-26*

It's free, it does what it says,
Great addition to the AUv3 library.

Thank you 🙏⭐️⭐️⭐️⭐️⭐️

### 5/5 — Habe nichts erwartet....

*2020-06-11*

Und habe sie sofort gemocht. Richtig gut. Danke

👍🏻

### 4/5 — Great tool, needs full screen view for GarageBand

*2020-05-04*

It’s a wonderful tool for creating really unique sequences and sounds - I can even use it for custom sidechain but with my fingers on more buttons, which is great - but it lacks full screen view for GarageBand. Thus, the UI is tiny... usable, but very tiny.
