Wired midi is a balanced current loop running at
19.2kbps.
Not 19.2. It's high but not insanely high, somewhere in the low tens
of kbps I think. However, I'm quite sure it's not one of the usual
serial-port speeds, which rules out 19.2 kbaud.
It's also *opto-isolated* current loop.
For obvious reasons, low latency is extremely
important and noise is
intolerable.
(In typical - and even moderately atypical - applications, of course.)
I've never liked MIDI, because it has no way to send a bunch of
messages to set a bunch of notes up and then trigger them all at once.
You have to simply depend on its being fast enough that the ear can't
hear the delay....
