Strange one. On opening this plug in you will get a warning saying that there is a missing wav file that should be in a particular location. Looking into it, the developer says in his notes that the sample folder is set to a certain folder on a certain drive - D drive to be exact. So unless you make a folder on your D drive(if you have one) the plugin will always be looking for it when it opens or changes presets. Abit of an over sight really. I sorted that problem, and it sounded okay, but when it stopped working and crashed my DAW, that's when I deleted it.
