FunktrackerGOLD is a port of the DOS32 Funktracker 1.08d editor (See MSDOS days page). It was ported late 1995.
Written in C, FunktrackerGOLD is used to compose digital audio music through /dev/dsp (OSS) DAC output device (the sound card interface on early Linux kernel versions). As far as I know, this program was the first music module tracker written for the Linux/Unix environment.
