I do not remember which models I read about that did that and never owned a gameport joystick/gamepad with extra buttons. MIDI was (de-facto) standard gameport pins and using the UART wired to the MIDI input pin was probably more convenient than to read serial signals from the buttons but I do not know how common it was to use that pin instead of the button pins. https://retrocomputing.stackexchange.com/questions/24946/how-did-joysticks-with-more-than-4-buttons-and-all-those-extra-features-work-on https://retrocomputing.stackexchange.com/questions/24946/how...

In that thread ssokolow links reverse engineering for gravis https://github.com/prosper00/GRiP-duino https://github.com/prosper00/GRiP-duino and sidewinder https://github.com/MaZderMind/SidewinderInterface https://github.com/MaZderMind/SidewinderInterface, both are bitbanging joystick button pins. You couldnt ship joystick relying on MIDI as people still had plain gmeport cards, not to mention some sound cards didnt support MIDI.

  The sidewinder used MIDI for force feedback though, for models that had that: https://web.archive.org/web/20151220120836mp_/https://code.google.com/p/adapt-ffb-joy/wiki/SidewinderFFBMIDI https://web.archive.org/web/20151220120836mp_/https://code.g... Found this page that has a list of some 10 different protocols for sending digital signals from joysticks to a gameport: https://dosdays.co.uk/topics/joysticks.php https://dosdays.co.uk/topics/joysticks.php Other than the sidewinder and GriP protocols I have not managed to find any specs for the other protocols. I clearly think I remember from back in the day that using MIDI for extra buttons was a thing so it may be one of those other protocols did, or it could be that I am just wrong.

    Even FF is crazy, would that force a choice between FF and GM wavetable for example?
