Cool!

So much cool stuff to mess with. Click things and find out what they do. Nice raunchy texture.
It’ll sound great as you get where you’re heading.
Great presets and cool preset generator stuff, but also lots of ability to intentionally craft the sound you’re looking for. So much ability for motion and musically beautiful “stank”.
I love it as a mono synth, a sick four oscillator beast of a mono synth.
Very enjoyable.
I hope this developer has a poly synth coming.
I’ve paid much more for iOS synths I enjoy less, for sure.
Very cool and absolutely worth it for the price, imo.
