- `EXPAND_AUDIO_HEAP` or equivalent (prevent game from dying when adding new stuff) - Configurable max note count (emu check debatably out of scope) - Remove hardcoded sfx table limits + make sfx IDs unsigned - Implement fix for the™ audio crash - Remove useless sequence volume table - Reduce the funny spin lock (out of scope? Would increase load times substantially though) - Fix that one audio popping issue in synthesis US/JP (maybe exists in other versions too idk) - 0 tempo and 0 envelope support - Any applicable (non-intrusive) optimizations - Other misc. audio memes I can't think of right now
