John, I think you mean abc2midi. If so, it is part of AbcMIDI.

  abc2midi  - converts abc file to MIDI file(s).
  Usage : abc2midi  [reference number] [-c] [-v] [-o filename]
          [-t] [-n ]
          [reference number] selects a tune
          -c  selects checking only
          -v  selects verbose option
          -o   selects output filename
          -t selects filenames derived from tune titles
          -n  set limit for length of filename stem
   The default action is to write a MIDI file for each abc tune
   with the filename <stem>N.mid, where <stem> is the filestem
   of the abc file and N is the tune reference number. If the -o
   option is used, only one file is written. This is the tune
   specified by the reference number or, if no reference number
   is given, the first tune in the file.
