That would be more like flashing line by line rather than a continuous
horizontal scroll, right?

I'd likely be able to write (in a nontrivial amount of time) the
required code for matching Midi time to sound file time.  That's
reasonably manageable signal processing.

Correlating grobs to miditime would be another task.  And then, of
course, generating the equivalent of one long strip, and making that run
through, likely in a nice smoothed motion with some cursor following the
notes more accurately.
