Bla bla bla world best synth a joke

Nothing spectacular normal synth with some modulation options, and how sad to use established music producers to tell it is a wonder synth!
UA specific strategy for stingy plug-in policy, a tip, UA makes not the best plugins, other like softube Izotope brainworks make better job and pricely fair!
Be careful with the plug-in policy
UA is to stingy to give me plugins that I should get with buying a Apollo x6!
They write me that I could choose for 2000dollars and now I can choose some for 150dollar, that’s cheating!

My go to plug in!!

I just recently bought this plug-in and I open it up first before any other plug ins I have. Other synth Plug ins have not given me this much ease with making my own loops and samples!

Sounds absolutely stunning but the routing limitations are severe

I understand why UA is keeping its instruments on the simple side, but I wish there were features for advanced users in terms of modulation routing. If you're gonna charge $200 for a soft synth today (as amazing as this one sounds), give me a reason to buy it over Cherry or Arturia who offer substantial enhancements to classic designs. I haven't bought a plugin from UA for a couple years now (though I own a majority of them). I just need a reason to.

I don't often write reviews...

....but this is one of the best soft synths I have tried in a very long time. Absolutely love it!
