Hi,

Here's a review (I'm not a DD so can't sponsor you however).

General
* There is a new upstream version (16th October 2014).
* #764998 abcmidi: binary-without-manpage usr/bin/abcmatch
  Obviously you know this, but it would be good if a manpage was added.
* The file "/usr/share/doc/abcmidi/VERSION" seems redundant and can
  probably be removed.

debian/copyright
* You don't need to list abc.h, sizes.h, structs.h manually in the first
  section since they're already included when you say "Files: *".
* There seems to be some confusion about whether the code is GPL-2 or
  GPL-2+. Are you sure what you've put is correct? I see files with no
  copyright headers but nothing with "GPL 2 only" in them.
* You don't need to repeat the GPL header lots of times. I'd also be
  tempted to merge all the GPL sections together and just have a large
  "Copyright:" block.

debian/rules
* I don't think you need to use autotools-dev in this package (I don't
  know a huge amount about this though).
* The clean target doesn't work because you disabled it. This is a
  violation of debian policy (4.9) "clean (required): This must undo any
  effects that the build and binary targets may have had"

debian/patches:
* Make sure you send these patches upstream (sorry if you've already 
  done this - they're not in the new version though).
* hardening.patch: Only LDFLAGS should be passed during the link stage. 
  Remove your CFLAGS and CPPFLAGS additions.

Build
There are lots of bad warnings printed when building this
Examples:
* parseabc.c:1701:3: warning: format ‘%s’ expects argument of type ‘char *’, 
but argument 3 has type ‘char **’ [-Wformat=]
   success = sscanf (s, "%%abc-version %s", &abcversion); /* [SS] 2014-08-11 */
 
  Isn't this a buffer overflow?!

* toabc.c:1490:8: warning: iteration 7u invokes undefined behavior 
[-Waggressive-loop-optimizations]
   semi = convertnote[i];

It's not too difficult to use these to make abc2midi segfault - please
try and fix them if you have time.

James
