I don't quite understand why the puc only provides a DIN connector for MIDI, rather than also USB MIDI
but I guess it's because it has no bwains in it
but it seems to me a modern Raspberry Pi with a USB-MIDI DIN dongle would be a lot more useful for modern controllers if there's anything to the "everything should be wireless" rhetoric
