ZPSDX! Finished, love it! but one last thing grrrrrr

[ggarms]

Honestly, i'm loving this thing. I am having one problem. When i'm past 9 or so on the delay pot (quick repeats), the entire pedal goes wacky- almost like mod is turned on and cranked and slam is being pressed on and off. As soon as I back it down to a bit slower repeats it is fine, but not having 25% of the delay range doesn't sit right with me. any suggestions? Thanks!
