The UI in SampleWiz may seem a little goofy and cluttered, but it allows for a great level of control and provides a number of different possible uses. You can play it as a straight-up sampler or you can take it to new levels of crazy resampling, and everything in between. I was initially put off by the clutter, but I respect it for all that it allows you to do, and that is quite a lot! Fortunately its complexity is easy to get into with a handy "Help Mode" to describe any of the many controls. Some of the key features are the ability to play with the waveform or play it along a keyboard in different scales. I wish the keyboard was similar to MorphWiz, which allows for assignable morphs along the vertical axis of keys.
