Realtime Filter change w/slider ?????

Q1 and Q2 sliders can control realtime tuning and level parameters but when I try to control filters with either the sliders or Q3 or Q4 knobs. I hear no changes to the sample. Any help would be graetly appreciated. By the way just in case any smart a$$ wants to respond with "RTFM" ... I DID !!!!!
pages 49-51 and pages 82-84 to be exact
Thanks again

Figured it out.
Had to turn filter on mode + pad 7 then f2. Just in case any one else ran into the same problem.
