This is a really good direction to be going in.

As well as pseudo-melodies it will be possible to extract short
sequences of notes from a library of .denemo, .midi, ... files. This
would give musical dictations that had a better relationship with actual
music (more natural sequences).

We have quite nice scheme procedures for moving the cursor to the start
and doing NextChord and GetNoteName for comparison with the next note in
the melody. Mismatches can then be marked with an X, and so on. (Those
command names are off the top of my head, so probably wrong - but real
examples abound in the d-CreateChordsOverBass script, where the cursor
is moved along the bass line and the MIDI-in is monitored for notes
which are compared with the bass note. Nils may have even more
sophisticated routines available).
