This popped up yesterday : https://ultra.audio/

Anyone know who is behind this soft synth or anything about it? going to try demo in a bit, seems pretty polished?

 

Thanks for the link, @Bert Midler Biddy Fiddler. I registered, downloaded the demo, and installed it. The controls work, and the user interface is convincing. I'm not entirely sure about the sound; I'll test it a bit more to see if I like it.

I don't know anything about the manufacturer. It's rather strange that you can't find anything anywhere else...?!

Wouldn't be surprised if they just used Surge XT's code lol

yeah, that lack of background info is puzzling, hence i asked here? A heavyweight pretty spec'd out synth just appears from no where....

 

Hoping to see it in the museum soon, it does seem reminiscent of surge but the interface catches my eye… don’t know if there’s maybe a way to give surge a skin like this since it’s open source…

poking around it now, clearly commercially oriented, its got a meaty supersaw section for those big trance pads...

 

Not officially launched yet.

 

Actually the wavetable creating part is very interesting but interface is really awfull, lost of lost empty space, not presize, looks like an Ipad or Web App nonsence

 

Developers put out the same type of synths that exist, imo, it is pointless and the market for such wavetable synths is oversaturated. But there are still gaps that noone want to fill. For example I would buy a good modern additive vst with lots of control (think Harmor, but with per partial parameters), modern CPUs are powerful enough to handle such thing.

 

Look here...!

Vertigo is a professional additive synthesizer with 512 Euler-generated oscillators and a -120dB signal-to-noise ratio.

"we have a couple of new oscillator types that we haven't released, we're going to add these as updates over the course of 2026".

It's not even released yet but the "magic update" is already planned...

 

Im just testing right now... I'm impressed how reverbs fx are good... The weakest point is wavetable... sounds not good quality as should be... Promising synth...

 

I get the demo and tested. Very different in term of sound to Serum or Vital or Pigments, to my taste has a powerful sound, the oscillator are live and punch and the effects sounds good. I don't use presets, I make my own synths sounds inspired in the golden Synth Pop and Eurodance era, and this Ultra really convince me a lot. Thanks.

 

What's the limitations?
