HI all I've got a midi keyboard that has onlya usb port to be connected to a personal computer. I'd like to connect this port to an arduino board and to manage midi signals coming from midi keyboard as if my arduino were a pc. That to say, arduino would receive midi signals and would transmit that signal thru a real midi port. Further arduino could do some processing beforetrasmit midi signals, for example holdin a chord or gatin a chord.
So I would could use my keyboard as master keyboard to drive other sound generators, keyboards with real midi port
Could you give me some hints? I read a lot about arduino or leonardo used as hid but never about host usb.
thanks in advance alex
