But… I’ve connected my Yamaha P-515 electric piano to my iPad, and it doesn’t show in the app’s “MIDI keyboard” dropdown.
Lots of Googling comes up with nothing helpful - or understandable, at least, to me, a novice when it comes to MIDI.
I’m writing this feedback, not because I want tech support, but because maybe it is helpful that a keen would-be user simply can’t get started.
