Beautifully simple.

Love the sound. Love the simplicity of programming this that can yield amazingly complex sounding results. Well done UA. I bought this and the Opal and they are both stunning.

good analog sounding Synth

Like and use this one a lot. Yes, to be online its a little bit anoying, but for me at least its ok. I only work in my Studio.

inutilisable avec Cubase Pro 13

j'ai installé le synthé Polymax après avoir up^gradé de cubase pro11 à 13. Bien que le plugin soit enregistré dans mon ilock physique, dès que j'ouvre une piste instru avec Polymax, cubase plante instantanément. je me passerai de ce synthé. Dommage .

Great Synth, but...

Not usable for live performance, because you need an active Wifi-connection. Ridiculous!

Only works well when you're DAW is online

I use Cubase 13 Pro, I recently installed a full version of PolyMAX Synth and I've had issues with my iLok account ever since. I don't like having my DAW constantly connected to the internet, it seems the only way to get PolyMAX to load and run ok is if I keep my DAW online. Not having the option to work offline really sucks.

Great Synth, but terrible License scheme

When you like to use this synth offline (with a live performance or in an offline studio) this expensive synth is not a choice to make. The synth makes terrible noises when it is not connected to the internet. Although the synth is great, it will because of this never be extensively used like all other software that depends on an internet connection. No good for musicians on the road!

You've just entered the world of synthesis music ... this one is a must

What you need when you start in synthesis music ? A reliable, straightforward, easy to use synth with accurate modelled oscillators, creamy filters & snappy envelopes all implemented in a user friendly interface & PolyMax is genius for this. You have everything needed to understand the fundamental of synthesis. Both LED amp & filter envelope help you understand the goal of an envelope. You don't need to dive & get lost in sub menus. All is there ready to use. Last but not least, the sound of the analog-modeled oscillators are a faithful recreation of an era that you should all start with when you want to start in sound synthesis.

EASY to program

The presets that come with it are good starting points. Spending a few minutes to to make them your own really transforms it into something special. By dialing back the effects and tweaking the envelopes slightly I now have a great collection of playable patches. If you want long-evolving, one-note weirdo sounds that require 90 modulation sources, this one is not the best option.

I've downloaded quite a few of these kinds of synths. This one really is exceptional. Some really nice ARPS, very clean, smooth and tastefully done. Just started delving into it without even using any modifications on sounds. This has creative potential as the sounds will mix in very well with various projects. Hardly ever leave a review but this deserves one. Nice work!

Superbe mais inutilisable sur scène !

De superbe sonorité et une interface facile à explorer. Malheureusement, du fait de la licence ilok cloud PolyMax ne fonctionne pas sur mon mac quand je suis sur scène loin d'une connexion internet. Le transfert de licence ( du cloud Ilok vers l'ordi ) est peut-être possible mais particulièrement mal documenté. Par conséquent je ne l'utilise plus et j'ai donné ma préférence au GX-80 de Cherry audio dont les modalités de licences sont nettement moins alambiquées. C'est dommage de devoir renoncer à de belles réalisations du fait d'une stratégie de licence tiers qui manque de souplesse.

WOW!! just wow!!!!

I'm not a guy that writes reviews, and don't get me wrong I love my other UAD plug-ins... Wasnt really expecting much from this plugin which came bundled with others I wanted. But to my surprise it is amazing, the clear vintage sound, the simplicity and great presets, make this a must! Thanks, UAD!!!!

Fantastic & FAT.

Being a long-time Roland fan (I used to own a Juno 60) I had considered getting the Roland subscription so I could access any of the Roland Synths. But when I listened to this synth, I realized this synth was all I needed. I was rewarded even more once I started using it and going through the presets. I've already added it to my primary template for Cubase. As a a writer and producer I feel I found the pot of gold at the end of the rainbow.
