I am not a big fan of compromises and shortcomings. All Roland has to do is combine stuff they aleady have in really obvious ways to provide a far more useful keyboard with little additional cost. If I were upgrading to a new arranger now based on available, announced and rumoured products, I would go with Yamaha (PSR9000Pro) or Solton (X1/X4). If Roland would follow a few of the suggestions in this thread, I would go with Roland.
