nanopad

hello guys, firstly let me say i wasnt sure if i should have put this post here or in mappings, so mods, feel free to move if you like.

ok, my little bro has just bought me a korg nanopad, im trying to use ean's mapping from the we will rock you video. however using tsp2. the problem im having is the fx parameters are changing as they should but the dry wet is not working.

any ideas?

cheers for any advice.
