Here's some printable manuals and cheatsheets for various music trackers that I've put together over the years:
- AHX - Abyss' Highest Experience - last updated: 27/7/2010
- Protracker Command Reference - last updated: 21/2/2012
- The source Word document has been lost. 😥
I'll probably re-write these in a modern, portable format like Markdown so that they can be read online or converted to LaTeX or PDF nicely.
Pull requests and documentation contributions welcome!
