Hi Lars,
thanks for your reply,
I have carried out thse steps a number of times, with no success.
The StudioLogic Numa Compact 2 (NC2) is listed as a supported hardware device, and Cubasis LE3 is connected to the keyboard via the apple camera adapter USB to an iPad Pro with ios 13.4.1 and Cubasis can see the keyboard notes as they are pressed, but Cubasis LE3 stays in demo mode.
Any other suggestions?
