Scott, unless I misunderstand your post, I disagree.

If you plug a stereo pad into input 1 (kick) using a stereo cable, input 1 is
capable of triggering 2 seperate sounds - one for PAD 1 and the other set to
RIM 1. I currently use this for an extra cymbal on the pad and a cowbell on the
rim of a TP80S.

So if you plug 2 mono cables from 2 kick pedals into a "splitter" with a stereo
output, this stereo output will then be plugged into input 1 (which is stereo)
and would be considered the same as a stereo pad, such as a TP80S. You then set
up RIM 1 and PAD 1 to the same kick voice and you have a double kick.
