A more appropriate term might be "modulated MIDI", because these formats generally involve MIDI data bytes modulated into a digital stream that can be carried by an audio channel using frequency-shift keying or phase-shift keying, similar to how raster data are sent over a telephone link via FAX.

I don't know about the internal workings of the PD system and whether the data ever really exists in analog form. Since the PD is made to be compatible with a variety of audio recording and playback devices such as MP3 players, my guess is that it might actually be converted to analog audio and then decoded into MIDI.
