Arduino music pad, capacitive sensor altenatives

Hi, I want to realize a music pad like that http://www.google.it/imgres?imgurl=http://www.synthtopia.com/images/mpd16top.jpg&imgrefurl=http://www.synthtopia.com/content/tag/drum-pad/page/3/&h=274&w=347&sz=19&tbnid=Z-KiJxsRn6tAfM:&tbnh=90&tbnw=114&zoom=1&usg=__P3JNgZ-LMVspL8-hFCQbhabYv60=&docid=8jq7vBLiq0vxLM&sa=X&ei=pzlAUpj6DsmjhgeD0oGACA&ved=0CD8Q9QEwBQ&dur=139. This project involves an Arduino DUE and different capacitive sensors... but CapacitiveSensorDue library doesn't work properly (http://forum.arduino.cc/index.php?topic=188109.0), are there any other solutions instead of using capacitive sensors? I would like to use a sensor which can response to human touch.
