### 4/5 — Simple and fun, but emphasis on simple

*2013-07-27*

This is a fun little step sequencer that has you creating music in seconds flat. My only complaint is it might be a little too simple. There are very few presets, a rather small grid and no option to import your own sounds. Without those features this is little more than a toy. That said, I assume it was the intent of the appmaker to create something basic and fun. If that is the case, this is a success.

### 4/5 — センスの良さはさすが™...ARTです

### 4/5 — ピコピコサウンド

### 5/5 — Real fun

Played random compositions with friends. Like digital new instrument.

### 5/5 — いいね。

*2011-06-15*

癒される。使い道ある。

### 4/5 — Pretty fun

*2011-05-21*

Simple, fun

### 4/5 — 素晴らしい

*2011-05-08*

あきないですね
ただ、再生中にサイドボタンで音量変えるとうまく音が出なくなります

### 4/5 — Strange but Good

*2011-05-08*

I like this app in this way!

### 5/5 — いい

*2011-05-02*

シンプルですがハマります

なぜかどんな曲でもうまく感じます

### 5/5 — Simple and Gratifying

*2011-04-25*

Playing around with this straight-forward mini-composer is a joy.  Compose your sequence over any of four repeating drum beats -- either add a considered composition or just add notes at random, it all works, and pretty soon you have a nice little soundtrack for your next minute or two.  The beats and the tones are all enjoyable, and the minimalist animation adds a surprising amount of happiness.  Bravo!

### 1/5 — iPhone X issue

*2019-12-26*

Seems to shut down on some more complicated stuff.

### 1/5 — Nur Spielerei

*2015-12-25*

Leider kann man nichts speichern oder bearbeiten. Nur rumspielen ist zu wenig.

### 1/5 — ???

*2012-04-10*

Das App funktioniert bei mir nicht. Es ist nichts zu hören und ich hab keine Anleitung, sinnlos, werde es löschen. 
Würde KEINEN Stern geben.

### 1/5 — 音でない(♯｀∧´)

*2011-08-30*

つけたらすぐ、音でない
がっかり(´･_･`)

### 1/5 — Incomplete

*2011-07-23*

It's not a composer, it's just a toy for making sounds.

### 1/5 — Too simple

*2011-04-12*

It's like Melodica, only not as good. And they should have put some info about the japanese relief effort in there somewhere, because as it is, this app doesn't inspire you to donate.

### 2/5 — Not working anymore

*2021-01-22*

A great, adorable app. 
Sadly not working anymore.
January 2021.

### 2/5 — Limited

*2012-08-14*

Very limited app - I guess it's ok for free, and there are no banner ads, which is nice, but it does not sound good. There are better free apps out here, so keep looking.

### 3/5 — sehr minimalistisch

*2014-11-17*

...für Ideen im Stil von Kraftwerk reicht's, mehr ist aber nicht drin.

### 3/5 — (^-^)

*2011-12-22*

Codeじゃなく音階が選べるのが良い。半音階が欲しいのと、深いディレイをカットしたい。

### 5/5 — It’s fun and it’s free...

*2026-07-17*

It’s fun and it’s free. Apart from a function to record/save your compositions [which is not included] what else do you need ? 
I like to ‘compose’: airport/airline IATA/ICAO codes*, abbreviations, short words, numbers, symbols, etc., and listen to them.

* I work at London Heathrow Airport [LHR/EGLL] so that is an advantage!

### 5/5 — Awesome Game

*2019-01-03*

Free, simple, easy to use and fun. It’s awesome!

### 5/5 — Thanks again...

*2014-01-22*

...to Masayuki Akamatsu too, of course!

### 5/5 — works...

*2012-10-20*

nice one...

### 5/5 — I'm the operator with my mini composer

*2012-05-14*

If you can't afford that expensive Kling Klang machine, start with this. Kraftwerk are gods!

### 5/5 — Pretty cool

*2012-04-16*

Simple but very fun! It's easy to work with, not complicated. If you're a Kraftwerk fan, you'll certain dig this app!

### 5/5 — Bon apli

*2012-03-20*

Assez bien pour une appli gratuite

### 5/5 — Best fun ever

*2012-01-14*

It's almost therapeutic.

### 5/5 — Love it!

*2011-12-23*

This app is simple and great. The sounds are sexy and smooth.

### 5/5 — We are the robots

*2011-12-12*

Great sounds. Saving them as iPhone ringtone will be nice. The app for every Karl Bartos & Kraftwerk fan.
