Re: [Bug 18992] Running status should be prohibited

Oh, I KNOW about it.  :)  It made a lot of sense, I think, back when MIDI
was typically running on a 31.25kb serial connection, and it took the time
to send a message from 3/4 of a millisecond to 1/2 a millisecond.  Over USB
2.0 (35 MB/s), I think it's not really necessary - or at least, not
necessary enough to force state maintenance between MIDI messages.  It
would be interesting to know how many MIDI software packages still support
it.
