FM synthesis

This is a music tracker 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.

You can see a brief demo video here: http://youtu.be/xQQvtjI7THg

The heart of any FM sound synthesis technique are the ratios used between the carriers and the modulators. Presented in this project repo are the decodings of the integer ratios in the Yamaha DX7 et al.
