If this has already been address, ignore.

If there were a stray ground pathway being generated, then simply 
picking up the hihat pedal and touching the metal frame of the KP65 
could trigger the KP65. Also, can you try to simply put a piece of 
rubber on the bottom and top of the HH65 to "electrically" isolate it 
from everything, including you, to see if that eliminates the 
problem. If it does then you may have a loose wire and surgery maybe 
required.

As far as sensitivity, if you take you finger and tap the flat part 
of the KP65 frame that sits on the floor with the two spurs in it, 
does the Piezo trigger. If it does, reduce the sensitivity down until 
it no longer triggers. 

Also, another thought:

Check to see if the voice for the Footclose has only one voice 
assigned and not two. If a cross-velocity setting between voice 1 and 
voice 2 for the footclose were setup so that "light" pressure on the 
HH65 would trigger voice 1 (hi-hat close sound) and a "heavy" 
pressure would trigger voice 2, then this would make sense, that 
sometimes it triggers/sometimes it does not.

If you goto the voice edit mode (and learn mode is on), press down on 
the hihat pedal to select:

KIT IN= footCl V=1
=H/015 K13 Clse     [This line will vary based on what you have setup]

Tab up to select V=1 using the <-Sel-> button and then change to V=2 
using the <Val +> button. The default is:

=K/000 NoAssign

If you accidentally changed this to K/001 or any other voice number, 
then the bass drum sound could be triggered when pressing down on the 
Hihat pedal.

Hang in there, we get through this.
