Nice breakdown video on the audio from the PS1 game SpongeBob SquarePants: SuperSponge. I did the audio code on this, and we used tracker modules all the way down. The whole audio was a module, with the main song taking up 10 channels. The sfx were small, multi-channel patterns that were prioritised and dynamically allocated the amongst the remaining 14 channels. Fun stuff.

And for all that effort? The game sold over a million copies :)

(ok.. I think SpongeBob may have helped with the sales a little bit..)
