i'm just trying to understand what jeff is describing. if i understand him 
correctly, the effect is equivalent to turning up the effect of accent on 
filter, plus turning up the env, because as jure just pointed out, the 
filter doesn't track note pitch. i did increase the env and the total accent 
depth on mine, but i think i'll do what you did, and just increase filter 
accent, because the volume accent is already plenty loud for my tastes.
