A stunner at the price, but in the scheme of things... – Kauldron Synthesizer Review

Quality-made, well-functioning app, but lacks the oomph of Model 15 and Zeeon, the analog-modeling standard bearers. Like Kaspar, in my opinion this synth is lacking in personality. Just like the other, it has a hard-to-describe ‘sheen’ to it that keeps the synth from busting out and sounding truly organic. There’s no oomph. Having owned all the other Yonac synths, this is something common between them all, so if you’ve liked that ‘Yonac sound’ in the past, I’m sure you’ll be satisfied. Still, this doesn’t offer anything new other than an excellent random feature. I don’t think you can do better for $4, but at regular price ($10), see Zeeon for your analog-modeling needs.
