Opus Composer was a music composition and playback package for Windows 1.0. It consisted of two programs, one for composing tracks (Composer) and one for playing them (Tapedeck). Only the shareware release of version 1.04 is currently available online. It 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 in shareware form.

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