Hi.
I think (its been some years) you need a cc4 of 120 or more (test w 127), and than a note on (being the 3rd note nr from the base note, as bow is base note, edge 2nd, pedal 3rd) which than both initiates the foot chick or splash, and quickly decays the open sound.
Very maybe, the cc is not needed because of pedal having its own note, not sure though...
