ym3812 is a fm synth chip, used in many systems during the end of 1980's and early 1990's.
Also known as OPL2 and "ADLIB" for PC, it was used as a poor midi player.
Fortunatelly, many people created some adlib trackers to use the true power of this chip.

These tunes used to be at: www.chiptune.de, the page no longer exists, look for "adlib music archive" or similar

The creator of Loudness tracker is called "Andras Molnar" (not Molmar).
