I tried to clean it up as much as I could, but the code is about is bad as you'd expect for being written in 1 weekend and then sloppily added to for 2 years. It's also now set up to automatically pull the latest updates from Github so tracking changes should be a lot easier.
You've probably noticed the recent increase in forum spam and people drawing inappropriate body parts on the sequencer. If anyone would like to volunteer to help clean up, reply here! It's not a commitment or anything, just gives you the ability to delete anything bad you come across.
