Maximum MODS is a compilation CD-ROM that works on MS-DOS and Amiga computers, and also (uniquely) boots up on an Amiga CD32 game console.
The compilation includes 4,233 "MODS" or "Music Modules". The MOD format allowed for full songs in small spaces (and computers) because it used repeatable sound samples containing individual sounds, notes or portions of music. The format allowed for both a MIDI-style sound and SAMPLED sound blended together for unique possibilities. The format originated on the Amiga with software like Soundtracker, Protracker, Noisetracker and was enhanced with other programs like MED and OctaMED.
Maximum MODS contains 14,512 minutes of music (which is 870734 seconds, which is 14512.23 minutes, which is just over 241.87 hours, meaning that it could play continuously for 10 days). At the time of its release, CD-ROM's were still fairly new territory and compilations like this were not common. Additionally, developers Syd Bolton and Adam White employed other techniques to make this disc unique.
Firstly, White developed an algorithm to identify duplicate music. At the time of its creation, Maximum MODS used various sources for its files including bulletin boards (BBS's) where users often changed files slightly and uploaded them in exchange for download credits. White's algorithm would identify similar tracks by creating a fingerprint of each song and then confirming the duplicates manually from a smaller list created by the computer. The technology, in essence, was similar to what software like SoundHound does today to identify music playing into a mobile device.
Secondly, White developed a front-end (in DOS) that displayed all of the songs and then launched an existing mod player to play the music. Bolton developed the Amiga version, and both programs shared the same music database file (although, for simplicity sake, the file is duplicated on the disc in its respective folder). This Amiga software was also used for the Amiga CD32.
The development of the product leveraged both the Amiga and the PC. The Amiga was used to develop the Amiga front-end of course and the cover art was created using LightWave 3D. The PC was used for the PC front end, the layout of the CD and instructions were done using Adobe PageMaker, and the software to determine duplicates ran on a PC using a database engine called The Manager.
The disc is unique in that it could boot up and work natively on the CD32 and also function on a PC and the Amiga. The special disc mastering that was required for this to work was done by Paul Reeves, founder of Asimware Innovations (who went on to sell his company to ioMega in 2001).
