Aren't the sensors just conductive rubber?
Or, are they piezo?
What does your tech say they are.
Rubber 'does" deterioate.(maybe just needs cleaning)
Piezo does not.(can crack, though)
PAIA made a "VelociTouch" kit way back.
it used one piezo to allow pitch bend and vibrato using keyboard
pressure. The piezo mounted under the frame of the keyboard.
it generated a voltage from piezo pressure,to modulate a vco/vcf whatever.
it was not a synth module, but rather a stand-alone, wood sided
ac, self-powered stand alone unit---whew!! long description!!
put the piezo on a chair; when you rock your butt, U can modulate
a vco or vcf. Would this be "playing by the seat of your pants"?
heh heh
i have data if anyone's interested.
