OK, so I have keywiz and I have it triggering VSA, but I want it to trigger with a pressure mat. Its not working ! It will trigger VSA when I put a wire across the 'enter' input to ground, but when I attach the pressure mat.... nothing happens. The mat worked until I cut the wires... The pressure mat was one that played music when stepped on.... I can't imagine that cutting the wires would make any difference..... but something happened....
