### 5/5 — Incredibly good

*2026-07-18*

The sound of it is insane. Simplicity really drives your creativity forward. I’m creating patches every single day. I only wish there was a vst version of it, so I could fire it up in Bitwig.

### 5/5 — It is amazing that is free

*2026-07-02, version 0.99.5*

### 5/5 — Awesome! What an App!

*2026-07-01, version 0.99.5*

Wow this thing is great! So much fun!

### 5/5 — Unfair

*2026-06-21*

It’s always the great ones that know how to function in society properly. 
What am I speaking about? Principles, character, good folk. The fact this is free is criminal. Do what they ask and leave a honest review. It’s crazy, cause I know that’s what they want. They don’t want you to say you like it if you don’t. What they do want is a balanced critique. So if you do not like it say why. Anyway the sound quality is bonkers. And not just like for an app. No the sound quality is ridiculous. Hook up a decent midi to this and it’s your fault if you can’t get something properly done.  Ok that’s it. I only poke my head out of my cave to leave these kind of things when I’m emotionally moved. I didn’t even mention the free stuff in addition to. Seriously you (synth one) should ask for something. Seriously.
