linux USB->MIDI with UART/serial comunication?

Sorry, if this is a lame question but I couldn't find a clue to that:

I know that linux has a module to recognize MIDI protocol through game port. I remember this module is called "mpu401-UART" or something like this...

could anyone have an idea on how we could do ftdi serial/UART communication beeing recognized as MIDI comunication? Maybe with a trick related to those "serial midi" modules?

(I know softwares like PureData could do that, but could be great if Arduino hardware could interface directly with jackd for example)

Please, links about that would help a lot.

thanks
