Found it at <URL:http://utopia.knoware.nl/~hlub/uck/rlwrap/#midi_input>
but I had seen it before.  The separate C utility makes it a harder sell
in my opinion.  It could likely be rewritten to use midi-kbd.el.

What it does do is trying to track the current "tonality".  That's an
interesting idea but requires an editing mode that will _propagate_
corrections in order to work nicely.  Of course, the same will be needed
in order to have automatic note length recognition cooperate nicely with
manual corrections, fixing later durations based on corrections on
earlier ones.

You probably mean not as much playing while entering (your MIDI keyboard
should do that) as you mean playing while editing.  midi-kbd.el retains
the full timing information.  So it is prepared for more complex editing
modes that make use of them, the simplest of course being just replay of
the current region exactly as entered (what to do with manual
insertions/corrections?  No idea).  Again, this is not yet done.  And
I'm not quite sure how to best do it: one would likely need to open a
(raw?) MIDI output device for it as well.
