These current pulses activate an octo-coupling device in the receiver such as a phototransistor. There is no galvanic connection between the devices; they don't share any ground or anything.
I don’t understand why this matters at all. The engineers who made 1.0 had different sets of constraints that we no longer have.
Now days we shove gigabits a second over cheap twisted pair wire. MIDI could do a lot more on modern or even decade old hardware...

- shawnz 7y agoCan't confirm, my newest motherboard's "line out" has actually been one of the best audio devices I've used in a while. And it's just a budget board.
