Z3TA+

*Very High Sound Quality

*Lots of presets & expansions

*Nice GUI

OVERALL - 8/10.....

they need to fix the modulation for the wave shaper.

I tried to get the demo. The site is still there and says to download Command Center to get it. But you can't sign up a new account.

Revisited this oldie today. 5 instances, ~45 polyphony, all 2x oversampled = 30% CPU usage, which includes all insert effects. They don't make synths like this anymore. One instance of Diva alone reaches 50% at high polyphony.

It's not really fair to compare this to Diva. They use different ways to make sound. Z3ta is a wave table synth and Diva is a virtual analog synth that what I think recreates the circuits of an old analog synthesizer. That takes a lot more processing power. Also you can change the quality in Diva. But I agree with you. Z3ta is an awesome synth.

Mac update here showing 03 march 2023, but latest available for download is Released: 3/6/2017

Too bad they just abandon it, not giving to free community like Surge synth. I would be happy for new free users even I paid full price long time ago.
