I'm reading through the documentation, it is not clear to me if when testing the transmission of MIDI data between App and Piano, an external android device is needed. To be more precise, Do I need to develop first, port the app into the smartphone, and then testing? or, can I simply plug the piano to the computer and the emulator will recognize it?
This will help me decide if I should manage a cable Smartphone-piano or Piano-computer.
Thank you for your help !!!
