I fixed, or at least altered the symtoms of, a
bug with tied notes across stafflines in abc2midi.
See the "patches" area (not a proper patch, just
a copy of my modified store.c).

Also: I have fixed two bugs with the display of
ties in abcm2ps.  Does anyone know how I can make
these fixes public?  It seems abcm2ps is not a
part of this sourceforge group (or any other).
The author has not (yet) responded to my emails.
Has anyone pursued, or is there any interest in,
bringing abcm2ps under the sourceforge umbrella?
It seems it would be of general interest.
Anyway -- for now, feel free to contact me for
the modified code, if you want better tie results
from abcm2ps.
