"Elegant, easy to navigate and sounds brilliant."

"I can't enough express how amazed and happy I am playing this app. Before writing this review I read the manual (you must) and tested every parameter until I understood perfectly how each one responded to the final output sound. I have to tell you the presets do not show how powerful this synth can be, you have to tweak by yourself every filter, modifier and fx's. For me the filter is the secret in this app to get a differentiated sound compared to your other synth app's. Filter adds a deep texture and resolution to the sound that I forgot lfo's and adsr's.”

"One of the best iPad synthesizers!"

"This sounds better than 99% of iOS synths. Filters are awesome. Modulation options are numerous. Effects are great. Sounds like a Mac plugin, not an iOS synth. Very little out there like this. I have paid hundreds on the Mac for this kind of sound."

"A wonderful synth with its own unique character to it."

"This app is excellent! Just enough of a twist on the standard synth app to make it worth the investment. Patch creation seems to be the focus, and UI is perfect for flipping back and forth while working out new presets."

"Huge tone that will cut through any mix Fantastic control options for the musician Rich sounds and a beautiful visual design A developer who cares greatly about his customers and creation (frequent updates) It's alive! Recommended!"

"Easy to lose yourself in sound design. The sound sources, fx, filters and modulations are all laid out to be very easily accessible. The mixer is great for tweaking the balance between the sound sources to fine tune your sound. Can tell some love went in to making this"

"Great, rich, full-sounding sounds! Great job!!!"

"Awesome updates from a developer who truly cares about both their customers and their work. Nice job!"

"It is FAT. The interface is intuitive. It is universal."

"This is really a fine example of a synthesizer whose developers love synthesizers. It is rather difficult to explain, but there is something within not only the interface, but in the nature of the sounds that this thing produces that shows their passion. This synthesizer is a patch designer's tool, not a preset player. Yes, it does come with some nice patches which show off some of its abilities, but when you start to dig in yourself, you can create some really unusual sounds."

"Excellent job guys. The GUI looks great and everything is extremely easy to access and in a logical way."

"Nice effects section great delay nice chord section IAA instrument support complete with transport bar and Midi learn. Good stuff."

### 5/5 — Simply genius

*2026-07-16*

I have this app on my iPad as well as the android version on my phone. I like the theme design and the sounds it makes.

### 5/5 — You will be amazed…

*2026-06-06, version 2.13.4*

if you’ve never tried DRC before. Superb alive and thick-sounding synth. Loads of YouTube tutorials. Buy it!

### 5/5 — Wahrscheinlich mein ein letzter Synthesizer…

*2026-02-27*

In den letzten Jahren gab es ja schon sehr interessante Apps (MS 20, Mono/Poly etc) aber der DCR schlägt sie meines Erachtens nach Alle! Die Filter sind wirklich großartig, die puristische Benutzeroberfläche ein Traum. Schon lange hatte ich bei meiner Klangforschung nicht mehr so viel Spaß. Der Preis ist nicht der Rede wert :-)

### 5/5 — Sounds incredible

*2025-11-14, version 2.13.4*

This is one of the best-sounding soft synths I’ve ever heard. For me, it’s up there with DIVA. It sounds so warm and alive. 

Despite a seemingly simple interface, the range of tones you can coax from this synth is expansive and wildly varied (as evidenced by the fantastic preset packs). 

I think some of the UI choices are questionable (like those buttons for choosing semitone tuning) but that’s a very minor gripe and one that doesn’t detract much from the sheer awesomeness of this synth. 

The fact that it’s available on iOS as well as Mac is just 👌🏻

Don’t sleep on it!

### 5/5 — A good app

*2025-09-25, version 2.13.1*

I like this app. I redownloaded it after I bought it years ago and it’s better than it was before. I like some of the sounds. They’re good.

### 5/5 — 高機能、高品質なアナログシンセアプリ

*2025-08-08*

インターフェースのデザインが地味だけど、理論的な配置で非常に使いやすく、出てくるサウンドはアナログらしい厚みがある。細かい音作りもでき、縦方向のスライダーに統一されているのでタッチスクリーン上での操作感も良い。単体でもAUv3のプラグインでも動作するので、AUM、LoopyPro、Logic ProなどのDAWでの使用も容易に行える。

**Developer response:** レビューありがとうございます！🙏 使いやすさやサウンドを気に入っていただけて嬉しいです。今後もより良い体験をお届けできるよう頑張ります！

### 5/5 — One of the best

*2025-08-07, version 2.13.1*

I have quite a few iOS synths, but this is one of the last ones I’d delete if I had to. The sound, design, experience, and developer support is among the best there is for iOS.

### 5/5 — Awesome

*2025-08-06, version 2.13.1*

One of the best music developers on the App Store. If this synth was a piece of sleek hardware it would cost $600 or more. Thankful to have high quality synths made with care in software format! Just buy.

### 5/5 — Please more  Cinematic presets 🌊✨🌞📸

*2025-06-07*

При покупке наборов звуков Pop Essentials, Timeless and Untamed их нет в папках и общих списках :///// Купил 2 новых наборов звуков а их нет :// Пожалуйста исправьте покупки : при покупке идёт загрузка и Установка Но самих наборов нет в списке ://
И жаль что ушли с 14 iOS :///(((

**Developer response:** Thank you very much for your support!

### 4/5 — Does what is claimed and balanced between too much endurable parameters and not enough

*2025-03-23*

Descent

**Developer response:** Thank you for your feedback and review! If you have any suggestions, feel free to reach out to us through our website.
