For me, as someone that loves Roland keybed PH04 and 05 feel but uses iPad instead of a Macbook with Mainstage for sounds in live performance, this adds class compliant usb. That is what really sets it appart from both the RD2000 and RD88 (which are not class compliant) for me. Main reason I didn’t pickup an RD2000 although I would die for its interface. I have an RD800 and RD64 both of which I love but RD800 is getting heavy and I really miss 88 keys on the RD64. All work with Apple Mainstage but not with iPad. Something like the RD08 will. I imagine at some point Roland may go class compliant usb with their flagship (have no idea why they haven’t accept maybe to lock you into only using their Cloud or Mainstage etc) but for now, if you use an iPad for things like Pianoteq, VB3, Audio Modeling horns and all the plethora of synth apps on iPad, this new board may be worth considering. I certainly has got my attention.
