Anonymous1 year ago000I can't connect my smartphone or tablet via Bluetooth via MIDI, only via AUDIO. This means that I can play songs from my smartphone via the keyboard speakers, but I can't "learn" with them in the Simply Piano app because the keys are not recognised... Does anyone have any tips? (Android, Simply Piano app & Casiotone CT S1 keyboard) Many thanks in advanceShow in original language (German)2 answersParsivalCyril1 year ago+110 Helpful answerSimply Piano does not support Bluetooth on Android so you have to use the USB connection so that the app can recognize the notes.
