I think that an optimal arranger would be one with styles as we know it and with Karma that would provide some variation and "improvisation" of some of the style tracks in real time. That way, we do not lose the huge and often very worthwhile efforts that companies have invested in the styles that are musically interesting. But we also gain a way to provide variation of some of the tracks in the style so they do not repeat. In short: the style provides the basis that is varied by Karma. Can this be done?
