Miles Sound System SDK 7.2a

FAQs and How Tos

Discussion

The Miles Sound System is a big API - pretty much anything related to audio is in there. MSS is logical, though, so once you "get it", most things will be second nature. Coming up to speed, however, can be a little daunting.

This is probably most important section in that regard - it will get you up and running quickly - pore over it carefully!
