[pluggo] tapped delay problems in pro tools

hi all -
I'm trying to use the tapped delay plugin in PT for a very simple thing, but I can't get it to work.
Essentially, the piece begins with a very quick delay at the beginning that continues throughout, while other things build up around it.
When I use the "host sync," the sync time is an integer, when in fact it needs to be a float (technically, it needs to be 113.43 ms).  The effect using the host sync though, is that by the end up the piece, the delay is out of sync with everything else (that .43ms adds up).
I've tried it using the free delay function, but whenever I do this, it always snaps back to the default 1000ms spot.  I've tried it in Live as well, and it still doesn't work.  It seems like there's something about having a tempo-based program that locks at the capability of using the free delay?
I could use the standard PT delay, but then I can't dynamically shape the sound the way I want as with tapped delay.
Any ideas?
