### 4/5 — hope for actual multi window

*2026-06-08*

Pretty great synth dded ro my library. I wonder if the app can be pushed further and have actual multiple windows from Flynth app: iPadOS 26 features.

### 5/5 — Worth it

*2025-11-03*

one time purchase. easy to use. presets are good. well designed. cant complain.

### 5/5 — Wow

*2024-12-02, version 2.2.1*

Wow such a good app! So clean so cool. And I only have the free version, crazy how underrated this is, please get it and support this dev!

### 3/5 — 这点功能不太值

*2024-02-23*

就一个vco 一个滤波器加一些基础的fx

### 5/5 — Awesome

*2023-12-10*

Well worth it

### 2/5 — Ganz nette App, aber für wen?

*2023-07-05*

Für Synthesizer-Einsteiger ganz okay, wobei auch hier erst die kostenpflichtige Vollversion zu empfehlen ist – und da gibt es schon jede Menge gute Freeware, die diesen Segment besetzen. Für jemanden, der mit Synths schon etwas anfangen kann, selbes Thema: ich wüsste spontan nicht, was diesen Synth von allen anderen unterscheiden soll. Vielleicht eine gewisse Unvollkommenheit – so klingen bei mir alle Bass-Presets nahezu identisch, Orgel wie aus der Spielzeugabteilung usw. Da hält sich die Lust, mit den wenigen vorhandenen Parametern zu experimentieren, doch sehr in Grenzen. Außer „lustigen“ App-Icons zu wenig zu bieten.

### 3/5 — Audiobus/iaa

*2023-02-16*

Just bought the full version and having trouble getting output. while it does connect via iaa on FL studio Mobile it will not play sound directly from there. I’ve tried matching MIDI channels or just leaving them Omni but still no luck. However, I do see the output signal while it’s routed when I open the Inter app so it there is a connection but I cannot get sound when playing in FLSM piano roll. Perhaps it’s so for an update or am I missing something?

### 2/5 — Boring, uninspiring experience

*2023-02-07*

I don’t like leaving negative reviews, but if you pay to unlock the full version, it doesn’t become eligible for refund in the App Store, so I think it’s important to call a few things out to avoid buyer’s remorse.  Many of the unlocked preset voices sound extremely similar.  Good luck differentiating between a lead and what this app generously calls an “organ.”  I like to support developers and thought maybe I’d find what was missing in making my own patches sound original, but it turns out you just can’t do very much with this synth.  Even the basic waveforms all sound the same.  I got this because I liked the simple design and thought it looked like it would be an easier place to teach my kid about synthesis than some of the more complex synth apps out there, but I can’t even use this to show him the difference between a sign and square wave sound.  When I opened the arpeggiator I could believe how basic it was.  No control of the sequence it plays notes in, how many steps it has, etc.  In fact, I thought it was non functional at first, because if you play a note with the arpeggiator turned on, it sounds exactly like it does with it turned off.  You have to play all the notes you want it to “arpeggiate” manually, and it steps through them in an order that you can’t configure or modify.  As I am more than capable of playing 4 or 5 notes in sequence far more expressively, the arpeggiator here is useless.  The effects are extremely basic. No panning or triplet settings on the delay, the distortion is hard to find anything pleasant in between too subtle and too mangled, there’s no chorus or flanger, it’s just… really disappointing for an app I paid for and can’t change my mind about.

### 3/5 — So-so

*2023-01-01*

Sticky keys, underwhelming sounds with little variation unless you go extreme and the FX are barely worth turning on. Just dull really.
