The generated would then run from the low octaves to high octaves
monotically, then start over again and again.

Maybe a more interesting approach might be to pick the note in the same
octave, the octave below or above, where the new note is closest to the
preceding one.

Using the closest note would have similarity with a random walk, given
π digits are seemingly random.  On a random walk, one gets away from
the departure point on average, the distance being proportional to
sqrt(N) where N is the number of steps.  So, when using the closest
note, one would need a corrective device nevertheless so notes are kept
near the middle of the range of comfortable audible frequencies.

There are surely many.  I use my own (Python) interfaces on Linux, and
even there, by combining a few tools, it is rather easy to get .WAV
files out of MIDI.  In any case, googling around might help.
