This granular synth is designed with a great UI, putting all of your sound design on one screen. This is also a limiting factor, not quite offering the same degree of control found in SampleWiz. Before the release of SampleWiz this was the defacto Granular, but I think SampleWiz edges it out in several important areas like resampling. It is still a lot of fun though, and very well thought out, to bring a great degree of play-ability to the messy business of Granular. The developer has a long history with iOS products and inventing new sound toys, as well as updating their existing catalog to meet user requests.
