### 5/5 — My arp

*2026-08-07*

I bought this when I was on the hunt for floaty pads and didn’t really find what I was looking for… but I fiddled about and made my favourite arp ever! I use it far too much. Then I made a nice clean sub-bass on anout 2 minutes. Intuitive app with great potential.

### 3/5 — Still no KT

*2025-07-22, version 1.17*

It still doesn’t have an essential feature like Filter Keytrack.
Several people have complained about this, disappointing that in all these years it was not addressed.

### 5/5 — Smooth layout

*2025-06-30*

I really like this very stable, well designed soft synth. I'm taking off one star because I feel like both main oscillator should have an independent amp envelope, for pads or whatever.. The low pass/High pass/ Band Pass filter etc section is very flexible, the best I've ever used in fact. I wish every synth had this type of manipulation. I've already created some very lush deep analog type pads. I don't really like the stock effects except the reverb and delay which are usable, and that's the main thing. I absolutely love omega too, I've made amazing rich sounds on it. I also own bleass reverb, filter and delay so I'm familiar with their workflow. Without sounding greedy, I believe that people who own the iPad versions should have a small discount on the Mac os versions and vice versa. I hope to see an update with the independent Amp Env especially...Thank you bleass

**Developer response:** Thank you for your nice, frank feedback, it's been heard.

### 5/5 — Un classique à avoir

*2025-02-28*

Très bon synth soustractif. Pas le plus complet mais l’un des plus agréable à utiliser et un des plus léger tout en permettant de faire pas mal de sons très différents 
<3

**Developer response:** Merci Julien, c'est effectivement la polyvalence qui fait son tout, entre (beaucoup) d'autres.

### 5/5 — Yep! STILL GREAT!

*2024-02-11*

Started out great. Recent update made it even better. I like the interface and the sounds I get out of it. Well done!

**Developer response:** Thank you for your support anickt!
We are already working on v 1.2 bringing even more new features and presets!

### 3/5 — One thing puts me off

*2023-07-20*

Love the sound and design of this synth but one thing puts me off using it. And that’s.. I can’t save MIDI mapping templates.

### 4/5 — 今となっては

*2023-06-13*

ごく普通のVAシンセ。
プリセットは課金して買うまでもないと思われる

**Developer response:** ご意見ありがとうございます。

BLEASS Alphaをご利用いただき、率直なフィードバックをお寄せいただき感謝いたします。プリセットや追加コンテンツの価値については、今後の改善に向けた重要な参考として開発チームで共有させていただきます。

シンセ自体の魅力や可能性についてより感じていただけるよう、今後もサウンド面・プリセット面の両方で改善と拡張を続けてまいります。

貴重なご意見ありがとうございました。

### 5/5 — Another winner from BLEASS

*2023-04-06*

First the negative…I’m not really a fan of the presets.
The positive: everything else. It’s easy to make your own patches that sound great thanks to the typically awesome BLEASS UI . Everything they’ve made before and after Alpha has held true to that. Everything is simple to use, but the level of depth is amazing. 

You need this synth….

**Developer response:** We appreciate your strong support and hope you're still having fun with us.

### 4/5 — Sounds great, simple…too simple

*2022-10-14*

Genuinely I love this synth, it’s easy to work with and I think it also sounds pretty solid for an iOS Synth, Actually close to my favourite in sound quality and vibe. It’s really well thought out and easy to use, quite intuitive really. I find myself making sounds I want to use quite quickly and easily. I love that it has two filters!  Being able to choose what goes to what filter and in what order would be useful though. There’s nothing overly negative to say about the synth except for it is a bit basic in features compared to some other current offerings…especially in this day and age of virtual synths. There’s just a few things I really hope might get added in the future. Examples would be a lot more Modulation destinations, it would be great to be able to Modulate the effects in particular but quite often I want to modulate something I’m thinking I want to hear in the sound and I can’t. It’s often quite frustrating in that regard. Envelope ADSR delay would be useful, also a loop option. I’d love another Modulation ADSR envelope as well. Envelope curve options would be super useful too for sound design. Visual representation of the Modulation on the parameters would be cool too. A pink noise option perhaps. Or being the fact it’s iOS maybe drawable LFOs or envelopes would be a Modern touch. The more I use this synth the more I Love it, however the more I find little things I wish were there. If you want a versatile, excellent sounding synth that’s quick to learn easy to program and good value for money this is it! Such a Good Synth by all standards.
Thanks A lot BLEASS for this Beast! Highly recommend

**Developer response:** Thank you for your valuable words, Daegelmusic.

### 5/5 — I don’t even have the right words

*2022-01-06*

At 47 years old I finally decided to seriously start making my own music. I took classes, been spending time learning and practicing. Watching a lot of videos on YouTube by pros and one of them mentioned this synth. Did some research and took the plunge and I’m blown away. It’s so easy yet so complex. I crafted my own sound and already used it in a project hours after buying it. Playing directly into Garageband is so seamless and perfect I can’t possibly give this enough stars. Keep doing what you’re doing devs - this is nothing short of spectacular and has inspired me to keep experimenting with new sounds. I’m in awe of what you’ve created!

**Developer response:** Thank you Jeff, we hope yopu're still having fun with us!
