### 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.

### 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

### 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?

### 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.

### 3/5 — Great way to learn, limitations for recording

*2021-11-06*

The animations for the LFOs are really helpful in understanding what is happening. Everything is intuitive and easy to read. AuV3 works well. I only wish there was a mono/poly/legato button, which would make monophonic basses more clear and powerful

### 4/5 — Easy and fun to use - some issues

*2021-05-26*

EDIT: The devs listened and added a SAVE-AS function! GarageBand menu still needs work.

Love Flynth! It’s much less daunting to use in comparison to something like audiokit synth one. The little animations are very helpful in understanding what LFOs are doing. I recommend it!

Although isn’t a problem when working in Garageband, however it makes no sense that being able to save a patch you made from tinkering isn’t possible in the native app.

You also cannot access user patches you’ve created from GarageBand.

=====Fixed======

However, there is a flaw that has not been addressed which seems like it should be a standard.

It’s missing the ability to save a synth patch you’ve created while tinkering on a preset. Currently the only way to create a user patch from a preset is to first copy the preset, THEN tinker. If you’ve already been casually tinkering with a preset and HAVEN'T copied it yet, you pretty much have to delete everything and start over on the same preset if you want to save it as a user patch.

### 3/5 — Save altered presets??

*2021-04-11*

Why is this not available on many of your apps? Huge limitation.

**Developer response:** You are totally right, we have added a "save as" feature to fix that in the last update 2.1, please install it to resolve this issue.

### 4/5 — Adorable

*2021-01-27*

Love the simplicity of the look, interface and sound! Would like to be able to modulate multiple destinations from one each LFO and would REALLY appreciate an amount control over the filter envelope going +/- but very happy with the purchase. Surprisingly difficult to find a sine wave Osc synth. Also I don’t appreciate the log curve on the cutoff, I fond it very difficult to hone in on bass tones (quickly). 

Also is it possible to save a version of any preset to a new user preset? 

Thanks!

### 4/5 — Great, back to basics synth

*2020-11-22*

Fun and easy UI. Fantastic tool to learn basic subtractive synthesis. Easy to make great sounds.

Would be nice for more detailed controls. LFO’s don’t go slow enough. Envelopes are rather touchy. 

Still a good overall simple synth.

### 3/5 — need help

*2020-10-26, version 2.0*

what cord do i need to use the midi function with my ipad?

### 3/5 — Buggy

*2020-10-22*

Great sounds, just purchased, but buggy as heck! Sticky keys, midi not working, running via AUM in iPadOS 14, please fix!

### 4/5 — Everything is nice, but...

*2020-09-21*

Nice sounds, nice controls, everything is fine, but! Please add preset library in auv3 mode, I just can’t fully use that synth because of that, it’s really hard to make sound from scratch every time, and IAA mode not suitable for big projects in DAW.

### 4/5 — Ganz nett...

*2020-09-18*

Aber insgesamt auch nix besonderes im Markt der ipad Synthesizer. Dafür läuft alles einwandfrei und lässt sich gut bedienen. Empfehlenswert für nicht-jeden.

### 3/5 — Great but still buggy seems expensive in current state

*2020-08-10*

Nice and easy interface, a bit too basic for some, but I guess that misses the point.
It’s super fast to make a nice sounding patch and the fx sound ok.

It is still buggy though and one of the features I love, you have animations for the destination lfo parameters, doesn’t always update. Sometime it just crashes not showing the pointer of the parameter which just disappears from the virtual pot.

After it’s finished it will be good, but SynthMaster 1 is only twice the price but about 10 times the synth.

Because of that it feels overpriced.

### 1/5 — Les effets ne fonctionnent pas ☹️☹️☹️

*2020-11-12*

Effets ne marchent pas

### 1/5 — Samples not what I needed; denied return

*2020-11-04*

I requested a refund after listening to the samples just a few days after but was denied a refund.

### 1/5 — Knobs do not turn

*2020-09-01*

Spent 10 minutes trying to grab a knob and turn....or, "tweak." But the best you can achieve is the knobs partially rotate, random direction, cursor does not attach to it. Click. Click and drag. Double click. Nothing.

### 1/5 — Used for about one minute

*2020-08-15*

Unable to use my computer keyboard to play the keys. No settings in the app. If you don't have a MIDI keyboard to attach, I doubt you will find this app useful.

### 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.

### 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.

### 2/5 — MacOS audiounit not available for full paid version

*2021-09-30*

Hello,

I’m trying to use full version on Mac and AudioUnit is not available in Logic Pro even after purchase. Please help. On website, there is no email Id in contact us.

### 2/5 — Using it with Beatmaker 3

*2021-01-22*

I purchased the app and i’m using it in Beatmaker 3. I cannot access the top of the app where you can cycle through the sounds. Please tell me im doing something wrong and how i can fix it. thanks

**Developer response:** Yes the presets browser was missing but we fixed that in the last update v2.1, please install it to get presets browser in AudioUnit.

### 2/5 — Forgot the KLEVGR logo?

*2020-10-04*

Because I swear I own this synth already.  But instead of Flynth, it’s called Hillman.

### 2/5 — The presets are really bad.

*2020-07-27*

Not much to talk about here. Most of the presets sound the same. The bass do not deserve to be called bass sounds.

### 5/5 — Simple but very nice synth

*2020-08-12*

This synth sounds good and is pretty fun to play around with making your own LFO modulated synth sounds. Thanks to the developer for the latest update, making the AUv3 a lot more complete! Awesome sauce 😎🤩🌟

**Developer response:** An update is now available with AUv3 new features: all factory presets, FX & Arpeggio, please update!

### 5/5 — Cool

*2020-08-07*

Классный простой синтезатор с кучей присетов. Порадоавло, что при покупке полной версии на телефоне она тоже разблокировалась. 

Спасибо разработчикам, отличный продукт помузицировать не сильно заморачиваясь.

### 5/5 — Beautifuly simple with amazing sounds out of the box.

*2020-07-31*

I used this for all of about 3 minutes and because it was a universal purchase, I just paid for the $4.99 for the full version. 

Over the last 20 minutes I have played with each of the presets and I love nearly all of them.   The standard Arppegiator and the FX are a nice add on and make this a true stand alone instrument.   

I am looking forward to playing with this on the ipad and midi setup later this evening... so far on the mac it is a breeze to setup midi and the sound is amazing through my studio setup. 

Like DM1, Just buy this..  you will play with it often.

### 5/5 — Awesome 🕺🏿

*2020-07-31*

Very happy with the sounds,really love this synth.
