This is a tracker (http://tinyurl.com/ye3ypcy) for MS-DOS that uses the OPL-2 chips present in AdLib compatible cards to generate sound using FM synthesis.
It was mainly developed using Borland Pascal (with some assembler bits by Keywiz) in a 386dx with a Sound Blaster Pro card, and even though it wasn't 100% finished, it was functional enough to create 3 demo songs which are included in the package.
I originally made this back in 1994 when I was 17 and active in the argentine demoscene...
