midi-kbd.el only translates Midi input into Emacs events.  Without any
keybindings on those events, it is useless.

Uh.  Maybe it uses a different mirror for Emacs packages or something?
midi-kbd is brand-new in ELPA.

Try typing r into the package manager for "refreshing".

Pity: Id have been interested in that.

The current version of lily-midi.el which I still need to fold into the
LilyPond repository does not do so either.

lily-midi.el converts the Midi events according to a "current key".  If
that key is C major, notes are

C C# D Eb E F F# G G# A Bb B

which tries to cover at least melodic A minor.  The scales it stops
working with are melodic E minor (Eb instead of D#) and Eb major (G#
instead of Ab).  If you set your current key differently, this scale is
transposed correspondingly.

The current functionality allows splitting according to Midi channels
(well, I have a Midi accordion) and works reasonably well for entering
whole chords.  It does not try guessing note durations.

And it's nederlands-only right now with regard to note input language.
