The code I wrote a year or so ago covered a large portion of the reverse 
engineering process.

The things it did 99% right were:
- loading the adlib "samples"
- loading the adlib tracks
- organizing the tracks into patterns 

The thing it did about 50% right were:
- playing the right notes
- playing the right samples

The things it did about 15% right were:
- playing notes the right length

The things it did about 0% right were:
- all the effects that I suspect the LDS format has.

A lot of it was worked out, but .. a lot was left to figure out.   The main 
problem with the code was that lengths were not played correctly, I was never 
able to figure out how those were stored within the data.  I was never quite 
sure if each "note" packet had the same length or if they varied under 
certain circumstances.

If anyone is interested in working on the code, I would be glad to help 
explain what the code there does a bit more.
