Yamaha DTXpress/DTXplorer/DTXtreme

I had posted a while ago about getting my non-yamaha HH pedal to work 
with my new DTX, but had no luck. Well, I finally got an HH-60 off 
ebay and it arrived last night. Very cool to have the open, closed and 
splash sounds. After a little fooling aound with layers and such, it 
sounds pretty good.

However, I do have one question though: On the Yamaha web site it says 
that the HH-60 has Fully open, closed, half-open, and foot splash. 
What I can't figure out is how to get the half-open sound. I get the 
open, closed, and splash, but don't seem to get an "in-between" half 
open sound, nor do I see a voice setting for this. It's not a big 
deal, but it would be cool to have that too. Any suggestions would be 
appreciated.
Thanks
