All this shows to me is how completely unique and flexible and easy to use the modern arranger is compared to the best workstation . Was not impressed with any of the arrangerish functions of karma . Could not see a real world scenario where I could use its functions in an arranger way . The beauty of arrangers is that although they are predictable in terms of looping patterns , they can be programmed to sound human . I have yet to hear a karma demonstration that sounded remotely like s human was playing .
