I should have stated that I made the pressure sensors myself.
I used a multimeter to measure the range of the sensor and it's roughly 0.25 kOhm to 4.20 kOhm so I'm thinking a resistance of about +- 2.1 kOhm should be used according to the people that told me you base the resistance on the average resistance the sensor gives ((max+min)/2).

Yes that sounds right.
Have you seen my midi footsteps project.
Oh wow it made my reply into a new topic..
The forum seems buggy to me, it has the tendency to log me out when I navigate through topics/forum sections.
