And to be pedantic, USB is not officially part of the MIDI spec, so that problem introduced by USB adapters isn't really a problem with MIDI per se. If you really want to interface MIDI with a computer in a fashion consistent with the original MIDI specs, then you can use an actual Serial port at MIDI's 31,250 baud rate, which is possible to do on a Raspberry Pi for instance (or on a computer which you could set your baud rate to that). Then you can get interrupts precisely when the MIDI notes arrive.
