music_formula_collection.txt
Collection of oneliner music formulas. Version 2011-10-18
I've tried to collect all the formulas in the related threads etc.
(excluding those that clearly sound like random first experiments or total
crap; when several variants are available, i've chosen the shortest one)
If you think I've missed something that should be here, please let me know.
