It was created by Psi (Sami Tammilehto), one of the founders of the Finnish demogroup Future Crew.
The first version (1.0) had monophonic 4-bit output via the PC speaker, as well as 8-bit output via Covox's Speech Thing (a digital-to-analog converter using the parallel port) or a Sound Blaster 1.x card.
As of version 3.0, Scream Tracker supports up to 99 8-bit samples, 32 channels, 100 patterns, and 256 order positions.
It can also handle up to 9 FM-synthesis channels on sound cards using the popular OPL2/3/4 chipsets, and, unusually, can play PCM samples and FM instruments at the same time.
The last version of Scream Tracker was 3.21, released in 1994, placing it in competition with FastTracker 2.
