Arduino by default enumerates its USB port as a virtual serial line (that's why
your device is named /dev/tty*). In order to automatically enumerate its USB
port as MIDI, you need a board with a processor that features an on-chip USB
controller so it can be reprogrammed to also enumerate as USB MIDI [1].

Alternatively, for Arduinos without on-chip USB, you can simply send your MIDI
via the virtual serial line and run a ttyMIDI daemon on your receiving host
which will mediate between serial line and ALSA MIDI [2].
