MusiCAD

MusiCAD is a scorewriter program originally designed for folk music[2] featuring irregular meter (like 78 or 1316) and automatically generated accompaniment voices (bass[3]/chords[4]) from chord symbols and specified time signature.

The name MusiCAD is a portmanteau of music and computer-aided design.

[1] Version 2.0 added support for multi-voice score editing.

Later versions do not focus that much on folk music anymore and will allow up to 32 voices as well as percussion notation.

The 3.0 version is available for Microsoft Windows and in Dutch, English and German.
