Just bought it and while it's easily useful for making cool sounds, especially when used with samples with lots of sustain (or using reverb before the plugin), the UI needs some work.
Specifically the dials turn way way way too slowly when you click and drag them when you use this on Ableton (this might be the case for other DAWs, but I only have Ableton, so I can't check the others). They turn so slowly as to barely move at all, forcing the user to type in the numbers manually to have any semblance of control.
That being said, the audio side of this plugin is very nice.
