I already knew the effect because I have the H9 as hardware and the plug-in version on my iPad.
But since I now work live with Ableton, I also treated myself to the VST plug-in version.
I already knew the GUI, which is identical to the iPadOS version and the GUI of the H9 app.
I love this effect, which I mainly use for guitar, sometimes for Vocal or Synth.
Sometimes very subtle for thickening sounds or sometimes for crazy "wobble sounds".
The sound quality is very good, as you would expect from Eventide.
There are a few YouTube videos about it...
