I have an older MacBook Air (2010) and have updated to Mac OS Sierra, and I can't get Logic to recognize my Roland RD-700SX anymore (at least with the USB cable, anyway). (I plugged in my Nord Electro 5HP, and Logic recognized that immediately. But my Nord is only 76-key, not 88, so I really want to use the Roland.) I hadn't tried midi on Logic for a long time, so I'd forgotten if there was something else I had to do, but based on this response, I guess my Roland won't work anymore, if Roland won't update their drivers? Is there anything I can do to use the Roland as a midi device anymore, if not with just a USB cable?
