Music in the Creatures series of games started out in Creatures as a variety of synthesized chimes, chords, bloops and other non-specific sounds, simply combined together into audio files (MU01.WAV to MU28.WAV in the Sounds folder on Windows) and played at certain points in the game or as certain applets were opened. This music was created by Andrew Barnabas.
For Creatures 2, a far more capable dynamic music system was created—MNG—and this system was also used in Creatures 3 and Docking Station. You can read about MNG files, which changed depending on factors such as location and the mood of creatures.
Editing and Playing Creatures Music
For games which use the MNG format, two tools are designed to edit the music, MNGPlayer and MNGPad - MNGPlayer lets you play music in the background (or foreground), while MNGPad allows you to edit existing MNG files and create your own. You will probably want to read the first part of MNG file format to see how the scripts work, although a tutorial is included with the programs.
The music of other games can be manipulated using normal audio or music editors.
Hidden within the audio directory of Creatures 2, an amusing musical track entitled 'DJ_G' is to be found, consisting of a Grendel repeatedly hitting a Norn to the sound of a techno remix of some of the sounds from the game. Upon the release of Creatures 3 a similar track was found in there. These may have been made by Mark Ashton. See also Defiant Doosers.
