monitoring via OT DIN Midi>USB cable plugged into Mac
i tested with a similar product i have too
i wouldn’t recommend the ESI one though fwiw - it is too clever for its own good as it tries to auto detect - i get an issue or two with one of its ports, but the other is solid, the other mid-price one i have is not so savvy with sysex - so i’m looking to get a proper quality one to avoid all headaches - probably an m-audio one, all the m-audio (midiman) midi stuff i have has been perfect, always !!
