Sound comparison

Metal, melody and sampled drums.

Earthsiege combines FM synthesis with digital percussion. Listen to the same 24-second excerpt through its OPL2 and OPL3 driver paths, then compare patrol and encounter music.

Each 24-second excerpt starts eight seconds into the piece. All excerpts retain the levels of the full renders.

The simulator chooses one of three paired scores. Threat checks can request the encounter version; the current track fades out, then the other starts.

The game’s HMI drivers decide which notes go to the FM synthesiser and which trigger sampled drums. We used those drivers and their 120 Hz scheduler to recover the arrangement and timing.
