Pretty Good Experience

This plugIn synth has great presets and tweaking them is intuitively, straightforward and lots of fun with cool results and very good sound.

When fader settings hit threshold, a small yellow light turns on - makes it very simple to find sweet spots!

Amazing Modern/Retro Synth

It has everything from big fat 80s sounds to new modern pop synth sounds. Lots of great presets for an almost endless stream of inspiration. Golden Warm Analog Goodness!

Awesome analog-style synth that's not a model of something that already exists.

I love the fact that UA is creating synths from scratch. PolyMAX is a great addition to the toolkit with a warm, vintage vibe reminiscent of classic analog synths from the 80's. The UI is great and is easy to navigate. Looking forward to more new creations from UA. Keep an eye out for a new preset pack for this one and also be sure to check out "SYMBOLS - The Lost Preset Pack for OPAL" on killerpresets.com .

The new modern-retro feel

Superbly hit character collection like jupiter, juno, oberheim....etc. Reworked modernized retro soundscape with uniquely effective "osc mod"feature and "modern-vintage" sound image emulation. Awesome !

PloyMax Synth

An interesting feature for me is the voice panning to generate wide stereo sounds and the entire handling of the plugin is very structured and correspondingly clear even for someone like me who is not a synth nyrth ... THANKS UAD

Polymax is a must!

I have owned a lot of synth software. I own komplete and I have several hardware units from Roland and yamaha. Polymax has become the most used synth in my arsenal.

First, it’s incredible! It sounds like exactly what I’m looking for, hi quality lo-fi and saturation. It does chill wave sounds and has a very simple and clean look. The presets are phenomenal! I will say this every time- I like Polymax more than using native instruments komplete. Not to mention the fact that other companies don’t answer emails. UA has had amazing customer service on every product I’ve ever bought. 5 stars! check it out in a demo and see for yourself!

Sounds vintage and warm!

Really really good for a software synth. As easy to tweak as a physical synth. Great presets.

I like it so much I wish it will become available in a tiny tiny roadworthy standalone DSP box for Fly-rig touring. For example I would love to see Polymax live in a UAFX casing with two midi IN for keyboard and a midi controller.

Sounds fantastic

It's sounds slick, and slots in nicely with modular set up and blends in well , the kind of poly synth I require in my mono synth world

Superb!

Wonderful simple, straight forward synth. The sound is amazing.
The new preset browser design for all the new tools are also wonderful easy to use. This and the Moog synth will be my new go to Instruments.

Outstanding

I am blown away by the richness in tone of this synth - sounds really beautiful and feels so warm and full. Gorgeous analogue tone. Well done, UA!

Excellent

This synth is just excellent. Simple, practical, and just fun to tweak. If you challenge the features vs. other available VA synths, you should consider that this one has many decent presets. You can hear that some valuable time has been spent creating them. I like.
