Digital piano can't be selected as input by Logic Pro X
My Casio CDP-130 digital piano has a USB out through which I have connected it to my iMac. The Audio MIDI Setup utility recognizes it, and the input and output tests are successful. Logic Pro X does not see it in Preferences>Audio>Input Device:. Logic does see it when I create a new External MIDI track, but that is for output.
When I turn the piano on, Logic notifies me: "Changed number of MIDI inputs/outputs. Now I input and I output are available." Then why cant I select the MIDI input?
Thank you for any advice.
