Thanks.  That is an interesting example.  I have mixed meters, and not
all beats are quarter notes, so I'd have to experiment...  I like VERY
much that the beat lines cannot be accidentally selected while
selecting notes.
Still, I have tempo markers at irregular intervals in the score, and
isolating them involves more skipping (of notes) than isolating the
notes does.  Neither notes nor tempo markers could be put in an array,
because both can be added at any time and have to be sorted according
to X before being played back.

Actually, playback works fine; it is when the patch steps through the
score all at once, to transpose all notes, that I run into overflow
errors.  I'll try deleting all the beat lines and see if it works that
way, and if so then your solution might work.
