Yeah, I've tried doing the pressure/tube route ( motorola pressure sensors
from Jameco ).  It does work but its too thick for what I'm playing with.

Whats gotten me started on this is playing with an Oberheim XK keyboard,
which like all 80's stuff has extremely heavy aftertouch.   While I was figuring
out why it wasnt working I looked over the aftertouch system and its
extremely easy and I wanted to play with it.  I also wanted to see if I
could find a new sensor that'd replace the XK's and that perhaps was more
modern and had a higher range of sensitivity.
