A public domain Python script that generates WOPL instrument banks from AdLib instruments in ScreamTracker 3 modules.

S3M files containing any sample instruments are not currently supported.

usage: s3m2wopl.py [-h] [-m] src [dst]

Convert a S3M to a WOPL instrument set.

positional arguments:
  src            source .s3m file
  dst            destination .wopl file

optional arguments:
  -h, --help     show this help message and exit
  -m, --monitor  monitor filesystem for changes (requires watchdog)

By default, all instruments are placed in the melodic bank in the same order as they appear in the S3M. Including a number in square brackets in the instrument name (ex. flute [74]) maps the instrument to the corresponding one-indexed melodic program number, and including a number in angle brackets (ex. kick <36>) maps the instrument to the corresponding zero-indexed percussion key.

Percussion instruments are played at C-2.
