### 5/5 — 郷愁

*2024-06-09*

ベル系、ノスタルジックなニュアンスを出したい時に重宝。各サウンドデザイナー達のパッチも素敵。このシンセのベル系プリセットで夕焼け小焼け弾くと一瞬で子供時代にタイムスリップできる。プリセットトゥイーカーの自分にはランダマイザーがあると嬉しいです

### 5/5 — Beautiful… Clean and Flawless

*2024-02-11*

Probably one of my favorites. Such a clean and defined sound that sends me instant sensations of frisson within seconds of playing with it…

### 5/5 — One of my favourite synths

*2023-11-03*

This developer always goes their own way, and this, like all the other icegear synths is very interesting and unique.

### 5/5 — Simply one of the the bests

*2023-06-01*

Many people be out here “taking iPad music seriously” since Logic came out but this baby has been around for a while and half the synths on PC and Mac couldn’t hold a 1 minute staring contest against Mersenne. 

This guy is “Magnifico” 🙏🏼.

Iceworks forever!

### 5/5 — great synth for mac and ios

*2023-05-19*

i have mersenne for the ipad, but on my mac i have to pay again for it.. laplace and lorenz no problem, i have installed them without paying again

edit: 
thank you for your hint @support, 
it worked and i could install it on my mac without paying again!

**Developer response:** I apologize for any confusion or frustration this issue may have caused you.

Firstly, if you have already purchased the app on your iOS device, you should not have to purchase it again on your Mac. The app should be available for free download on your Mac as well.

Secondly, the issue you have experienced is due to a bug in the App Store's display, and if you proceed with the download process, you should ultimately be able to download the app for free.

Lastly, I want to clarify that the issue lies with the App Store, and as a developer, I am unable to solve any issues related to the App Store. If you have any further questions or concerns, I recommend contacting Apple support for assistance.

Thank you for your understanding and support.

### 1/5 — Horrible sounds. A complete waste of money

*2020-09-18*

Looked good. Sounds awful and dated. My fault for not doing the research

### 5/5 — Outstanding synth app

*2019-12-17*

This synth app crushes everything it does! Sounds like heaven, has an ergonomic lay out on ipad and is still outstandingly comfortable on a tiny iphone 5c, uses so little hardware, needs only 7mo space, and it has all compatibilities with other apps you could wish for...
A real bargain for the price!
Grateful to obviously passionate and smart devs for this piece!

### 5/5 — Suuuperbe

*2019-12-05*

Mais j’ai toujours pas compris comment fonctionne le séquenceur

### 5/5 — Love it

*2019-11-11*

Lots of good percussive sounds coming out of this one and a lot more! Get it now!

### 5/5 — Great sister synth to Laplace

*2018-12-17*

I return to this synthesizer app, regularly, because it does what music apps are supposed to do, a unique sound with a simple interface.  Laplace is my favorite of the ice works apps, but this is a great companion/expansion to Laplace, especially for the billed use, tuned percussion. I do like Laplace better for strings and plucks and keys. This one is really fun to play with a drum pad midi controller (tuned to a scale, if you like) for marimba, and bell like sounds.
