Hola compañero alvaro revueltas exelente aportacion, tengo una duda, yo construi un controlador midi con pads usando un codigo que encontre en el foro, mi pregunta es como le integraria la utlidad que tu mencionas al codigo, soy muy novato en esto del arduino y me gustaria mejorar mi controlador y dejar de depender de la interfase midi usb que tengo y aparte darle alimentacion por el puerto usd del arduino, te dejo el codigo espero puedas ayudarme.

) y los músicos. He visto el controlador que enlazas y está muy bien, pero ya veo que no está protegido por debajo. En estudio puede hacer su papel pero en directo puedes perderlo fácilmente por algún golpe e incluso por humedad o cosas peores.
