Thanks Tom, very interesting. Had not seen a standard, but did not know whether
some recent MIDI spec may have defined a standard behavior.
I've only had to deliberate on the issue when displaying overlapped MIDI data in
a Piano-roll editor. One must decide how to display the piano-roll bars.
Whatever one decides, might not agree with how the synth actually responds to
overlapped MIDI events.

Impossible to guess, but an obvious suspect might be inadequate keyboard switch
de-bouncing.
