I am building a MIDI Marimba using the inwards of a midi keyboard. The keyboard is touch sensitive by using 2 switches per note. I already have a basic/starting circuit that will mimic the 2 switches behavior. It detects how hard or soft the piezo sensor was hit. I attach the piezo sensor to a wooden bar. (Eventually I will have at least 3 octaves of these bars). Question: Based on your experience with eDrums - and because I don’t have too many piezos yet to experiment - where are the piezos more sensitive on the flat metal side or the crystal side? Do I mount them with double tape? Does the double tape must cover all the piezo area or should it be small just to make the piezo vibrate?
Thanks,
Thanks,
