Isn't this very similar to drawing the midi-pitchbend? EditTrack did
that in the 80's. You could also draw values for volume and controllers
if you wanted sophisticated envelopes.

IIRC mouse-dragging in the piano-roll would "spray paint" notes all over
the place ... Combine that with a synth patch with very closely spaced
notes and we are getting pretty close to what you are talking about.
Perhaps with a bit of portamento to smooth out the rough edges
