Is the M3, OASYS, or Karma an arranger keyboard, or can it replace an arranger keyboard?
While some users report that they are quite happily using it in this manner, these Korg Workstations are not really designed to be an auto-accompaniment or arranger style keyboard. For example, there are no intro or fill buttons, and you will not find grooves in every style of music, such as cha-chas and rumbas. While it is true that some of the presets respond to LH chords and produce grooves that you can play on top of, there are also many other sorts of presets that do nothing of the sort, or do completely different things. One user has said “Conventional arrangers are good at replicating how others sound, while KARMA excels in allowing you to create your own sound. KARMA provides a lot more real-time control than a conventional arranger, and thus provides a lot more flexibility for a musician’s self-expression.
