Opus Composer was a music composition program for Windows 1.0. Only shareware version 1.04 is currently available online, which only supports PC speaker playback, while the full version also supported various MIDI devices. It was later renamed to WinSong Composer in version 2.0, which is also available online.

Despite a similar name, it is not related to the Opus One program from Roykore (though this could have been a reason for the name change).
