Some of the questions on the B4 software might be cleared by first downloading a free demo version from the Native Instruments site. I am still not clear on what are the features removed on the free version. I am glad that the software has been found acceptable and may get it later. I personally favor a trend towards software arrangers and computer sound cards, using keyboard controllers that do not obsolete so often. That way we could have more real-time levers, sticks, pedals, eliminating many buttons that are not for realtime use, from the keyboards.
