I wish I understood more... its the numbers, being dyslexic means I get a bit fuzzy in the head...
All I know is that drum loops where you retrigger them at beat 9 are my favorites, and that if I run one loop at 9 cycles against another thats running 5..that sounds great too!
And if you add all those numbers together you get 23, that strange re-occurring number that pops up too much! (See William Burroughs and Jim Carey)
