And yet, it was successfully used for serious MIDI work. It's simple: Don't use the serial port for MIDI.

Peripherals (via expansion port) can trigger level 2 and level 6 interrupts[0].

Notably, level 6 is the highest priority level in 68000, short of the NMI (level 7).

I have to agree with the parent, adding a MIDI port to the Amiga would have been trivial.
